Product Details

Class I NTEP Approved Legal For Trade The National Conference on Weights and Measures certifies the Ohaus EX423N Explorer Legal for Trade with Certificate of Conformance number 12-012. So, you can count on getting accurate readings time after time.

Modular Design The Ohaus EX423N Explorer has a unique modular design that allows you 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 precision balance. It features a full color, 5.7 inch, touch screen display.

Four Programmable Touchless Sensors The EX-423N Explorer 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 you 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, you don't have to be a rocket scientist to get this scale working the way you want it to. The SmarText software will guide you through the whole setup process with text prompts. After you 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 balance nice and accurate. It has automatic internal calibration that will automatically calibrate with a significant change in temperature, or every 11 hours.

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 precision 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 you need to do is weigh a sample amount of pieces, so the scalecan know how much each piece weighs, then start counting. You'll be finished in no time. Counting feature is NOT legal for trade.

Average Piece Weight Before you start counting your pieces, you need to let the EX423N know how much each piece weighs. Ohaus made this simple by averaging the weight of the pieces you put on the scale. Just type in how many pieces you 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 you! Just tell the Adventurer to send your data at user selectable intervals, when the balance is stable, or to only send it when you press the print key.

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 you to accurately weigh unstable items by calculating the average weight of what's on the platform. Great for animal weighing.

Checkweighing Make sure you get your weights just right with this scientific scale's check weighing feature. When you 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-423N will surely let you know.

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

Pipette Adjustment With the Explorer you can even check the accuracy and precision of your pipettes by weight analysis. Just select what liquid you 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 you to capture the highest weight in a series. Both stable and unstable weights are captured.

RS-232 & USB Ports The EX-423N has both RS232 and USB communication ports built in for easy communication with printers, computers, monitors and more.

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

Below Balance Weighing This balance is equipped to facilitate below balance weighing for weighing magnetic materials and performing density measurement.

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 you 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. It even has a level assist screen to help you figure out which foot needs adjusting.

2 YEAR MANUFACTURER'S WARRANTY! When you get the EX423N Explorer precision balance, you need to go over to the Ohaus website and register it to receive your two year warranty.
