Product Details
  • Class I NTEP Approved Legal For Trade

    The National Conference on Weights and Measures certifies the EX224N/AD Legal for Trade with Certificate of Conformance Number 12-012. So, you can count on getting accurate readings time after time.

  • Automatic Draftshield Doors

    The Ohaus Explorer 224/AD has motorized draftshield doors you can program to open and close with the wave of a hand. This handy feature helps prevent contamination and residue buildup

  • Modular Design

    The Ohaus Explorer has a unique modular design that allows ya to separate the display from the base of the scale. The touchscreen display allows for angular adjustment and can also mount on the wall or optional tower. The display "terminal" is attached to the scale base with a long cable that allows the terminal and base to communicate.

  • Full Color Touch Screen Display

    Ohaus went all out designing this analytical balance. The Explorer has a full color, 5.7 inch, touch screen display.

  • Four Programmable Touchless Sensors

    The Explorer EX-224AD is designed with four hands-free sensors, two on the base and two on the display, that make operation clean and easy, even with full hands. The touch-free sensors control the zero, print, tare and calibration operations and helps ya avoid transferring sample residue to the keypad. The two sensors can even be set up independently to control up to 36 combinations of operations.

  • SmarText 2.0 Software

    Thanks to this special software, ya don't have to be a rocket scientist to get this scale working the way ya want it to. The SmarText software will guide ya through the whole setup process with text prompts. After ya have your scale all set up, the software will even guide you through different weighing applications.

  • Advanced AutoCal™ Automatic Internal Calibration

    You won't have to worry about buying calibration weights to keep this analytical balance nice and accurate. This Explorer balance has automatic internal calibration that uses internal weights to calibrate the scale. The Explorer will automatically calibrate with a significant change in temperature, or every 11 hours. This is gonna come in really handy, especially if ya don't like maintaining calibration weights or going through the whole calibration process. If ya prefer to calibrate the scale manually, you can still do that too.

  • Ingenious Draftshield

    When you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. That's why this Ohaus scale comes with a durable, glass windscreen to keep out those pesky drafts. Oh, and don't worry, this scale makes it easy to put your items on, or take them off, the platform. The top flips up and the sides slide all the way back. That's not all! Ohaus designed this draftshield with antistatic coated glass, to help dissipate static charges in the weighing chamber that could affect the weighing results, and a chamber light.

  • Fast & Accurate With Magnetic Force Restoration

    This lab balance is equipped with magnetic force restoration, or electro-magnetic force, to provide super fast, accurate and repeatable measurements.

  • Does This Thing Count?

    You bet it does! All ya need to do is weigh a sample amount of pieces, so the Explorer can know how much each piece weighs, then start counting. You'll be finished in no time.

  • Average Piece Weight

    Before ya start counting your pieces, ya need to let the EX224 AD know how much each piece weighs. Ohaus made this simple by averaging the weight of the pieces ya put on the scale. Just type in how many pieces ya put on the scale, and the scale will average the weights. The bigger your sample is, the more accurate the scale will be when counting your pieces.

  • Programmable Auto Printing Feature

    This lab balance will automatically print your data for ya! Just tell the EX224/AD to continuously send data to the printer, to send it at user selectable intervals, when the balance is stable, or to only send it when ya press the print key. That's pretty handy if ya ask me.

  • Filling

    This feature can be used to accurately fill samples in comparison with a target weight. Just set your target weight by either weighing a filled sample or keying in your desired weight. Once your target weight is set, you may begin filling. The scale will display the target weight, difference weight, and difference percentage. There's even a progress bar on the display.

  • Dynamic Weighing

    This precision balance has a really cool dynamic weighing feature. This feature allows ya to accurately weigh unstable items by calculating the average weight of what's on the platform. Great for animal weighing.

  • Checkweighing

    Make sure ya get your weights just right with this scientific scale's check weighing feature. When ya weigh in this mode, you can set weight limits for the stuff you're weighing. So, if your sample weight is too low or too high...the EX-224 will sure let ya know.

  • Percent Weighing

    This feature will let ya compare the weights of your samples against a predetermined reference weight. This can be helpful in weight checking, compounding, formulating and more.

  • Totalization

    You can use this accumulation feature to weigh a sequence of items together. This is a great feature if ya need a scale with cumulative weighing for compounding ingredients. It's even okay if your accumulated totals exceed the scale's capacity.

  • Differential Weighing

    This process will store tare and weight values for comparison with samples to be dried or processed. You may store up to 99 different samples by name for future use.

  • Formulation

    Use this feature to accurately measure and compound your formulas. Formulations can be named and stored with two to 99 specified components. Each element in your formulation, as well as, the total weight of all elements are displayed at the bottom of the display. After you've added all of your elements, your formulation is complete.

  • Density Determination

    This analytical balance has four different ways to determine density. You can determine density for solids more dense than water, solids less dense than water, liquid density, and density for porous materials. All ya have to do is enter a couple of parameters into the balance, the built in density table and mass measurement provides rapid and accurate results. No manual calculations needed.

  • Statistical Quality Control (SQC)

    This feature is useful for monitoring filling operations to help avoid under filling and over filling. Up to ten batches with up to 80 samples per batch are visible for quality control purposes.

  • Ingredient Costing

    If ya use this scale for lots of formulations, this ingredient costing is going to come in handy. This feature will tell ya how much your formulas and recipes cost based on known costs of components and ingredients.

  • Pipette Adjustment

    With the Explorer ya can even check the accuracy and precision of your pipettes by weight analysis. Just select what liquid ya want to test your pipettes with, set up a few parameters and stand back; the balance will do the rest.

  • Peak Hold

    This feature allows ya to capture the highest weight in a series. Both stable and unstable weights are captured.

  • RS-232 & USB Ports

    The Explorer EX224/AD has both RS232 and USB communication ports built in for easy communication with printers, computers, monitors and more.

  • Stainless Steel Platform

    This analytical balance has a durable stainless steel weighing platform that doesn't scratch easily and will keep its shine without rusting or tarnishing.

  • Weighing Hook

    Sometimes the thing ya need to weigh just won't fit on the scale's platform. Now that's a problem for most scales, but not the Explorer EX224. This scale has a weighing hook built right into the bottom. This hook works by pulling on the weighing platform when an item is hanging from it, just like if ya were to put an item on top of the platform. This will come in handy for density determination, gravity calculation, and a lot more.

  • Tare Feature

    The tare button on the front of this digital lab scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when ya want to use a container to weigh your things.

  • Illuminated Liquid Level Indicator & QuadraStance™ Thumbwheels

    To get the most accurate weight readings from this scale, Ohaus designed the Explorer with an illuminated liquid level indicator and super easy to use QuadraStance™ thumbwheels for adjusting the balance. The Explorer even has a level assist screen to help ya figure out which foot needs adjusting.


    When ya get the Explorer EX224 analytical balance, ya need to go over to the Ohaus website and register it to receive your two year warranty.
