Product Details
  • -OPTIONAL- Rechargeable Battery Pack

    If ya choose to buy a model with the factory installed rechargeable battery pack, you won't have to worry about searching high and low for a wall outlet to plug your bench scale into. The Ranger scales with internal rechargeable batteries offer up to 30 hours of battery life on a single charge!

  • -OPTIONAL- Analog Interface

    The Ohaus Ranger Plus uses this optional analog feature to give you Two Scale Counting! This very useful feature will let ya hook up your Ranger counting scale to another scale or platform to give you a larger weighing space. You can also switch between scales if ya want to count big items on one and small ones on the other.

  • Six Models To Choose From

    The Ranger comes in six different models, the RP3RM, RP3RM/1, RP3RM/2, RP3RM/3, RP3RM/4 & RP3RM/5, each include all of the great features listed below plus a little something unique to each model. If ya want to see which scales have which features, check out the table above.

  • 100 Memory Locations

    The Ranger Count Plus has a 100 location memory for saving tare values, average piece weights, target weights and target quantities. This will save ya from having to punch in all that info every time ya want to count your items.

  • Auto Printing

    If ya hook the Ranger up to a printer, you can tell it to automatically print out your stable readings. This can come in real handy for recording and comparing your piece and weight data.

  • Average Piece Weight

    Before ya start counting your pieces, ya need to let the scale 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 Ranger will average the weights. The bigger your sample is, the more accurate the scale will be when counting your pieces. The sample amount can even be stored on the scale for future use.

  • Checkweighing Feature

    Make sure ya get your weights just right with this counting 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 Ranger will sure let ya know.

  • Class II NTEP Mode

    If ya plan on using the Ranger bench scales commercially, you'll be glad to know there's an NTEP certified Legal for Trade weighing mode on each of these bench scales with Certificate of Conformance Number 07-026. This sure is gonna come in handy for weighing and packaging your items to sell commercially. The NTEP resolutions are listed in the table above.

  • Dynamic Weighing

    These high precision scales have a really cool dynamic weighing feature. This feature allows you to accurately weigh unstable items, or weigh stable items in an unstable environment.

  • Programmable Sleep Mode

    The Ohaus Rangers have a bright, backlit weight display so ya can see your weights even in dim lighting. If ya use this precision scale on battery power, you can even set the scale to not use the backlight feature. This is gonna save you a lot in battery power.

  • RS232 Port

    Each bench scale in this series has an RS232 port built right in. This is important if you're wanting to send your data to a printer for recording weight readings and other data.

  • Tare Feature

    The tare button on this digital bench scale can be pressed to "zero out" the weight that is on the scale. You can then add more weight and the scale will only display the weights of the items you're adding...this sure is useful.

  • Liquid Level Indicator

    This very handy feature helps you quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings. All ya have to do is twist the feet on the bottom of the scale until the spirit bubble is centered within the level.

  • Stainless Steel Platform

    This compact digital scale has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing. Since the platform is removable, this food scale is perfect for weighing food portions for packaging and food preparation.


    When ya buy the RP3RM, RP3RM/1, RP3RM/2, RP3RM/3, RP3RM/4 or RP3RM/5 you'll need to head on over to the Ohaus website and register it to receive your one year warranty.
