Product Details

Programmable Touchless Sensors The NV4101 AM Navigator is designed with two hands-free sensors that make operation easy, even with full hands. The touch-free sensors control the zero, print, function, tare, and backlight 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.

One Second Stabilization Time This portable scale is designed to give you accurate weight readings, fast. The Navigator stabilizes in less than a second to improve operator efficiency and productivity.

Overload Protection The NV4101 AM has overload protection that can withstand up to 400% of its capacity. This protection system will help prevent damage to your scale from accidental overload.

Programmable Auto-Off Feature If you've ever had your scale turn off on ya in the middle of important measurements, you'll realize what a blessing this feature is. You can program the Navigator to turn off automatically, or to stay on until you turn it off yourself.

Tare Feature The tare button on the front of this industrial 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 item you're adding. This sure is useful when ya want to use a separate weighing container or get the weights of separate items.

Hold Feature This feature lets ya remove weight from the scale and keep the weight reading on the display. This sure comes in handy if you're weighing big box, or if you're having trouble seeing the weight display.

Stainless Steel Platform This portable digital scale has a durable stainless steel weighing platform to make cleanup a breeze. Unlike plastic, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing. This is a great feature if ya want to use the scale in an industrial setting.

Easy Calibration The NV4101 AM Navigator is factory calibrated and ready to use right out of the box. Once calibrated, this portable scale rarely needs calibrating, but if ya use it ALL the time, or ya just want to be sure you're getting the most accurate results ya might want to calibrate it from time to time. You'll just need to pick up two calibration weights, (1) 2 kilogram and (1) 4 kilogram, to get the job done. This scale has two calibration modes; Span and Linearity. Span calibration requires 2 kilograms of weight. Linearity calibration needs two separate weights, one 2 kilogram weight and one 4 kilogram weight (not included).

Does This Thing Count? You bet it does! All ya need to do is weigh a sample amount of pieces, so the NV4101 AM can know how much each piece weighs, then start counting. You'll be finished in no time.

Easy To Clean, Sealed Keypad You won't have to worry about dust and dirt getting stuck under and around this scale's buttons. The Navigator has an easy to clean membrane keypad with accurately labeled keys for easy weighing.

Illuminated, Liquid Level Indicator This very handy feature will help you quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings.

Integrated Shipping Lock If ya plan to tote this thing around quite a bit, you'll be glad to find an integrated shipping lock right on the bottom of the scale. This lock will help prevent accidental overload and damage to your scale.

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 repeatedly add the amounts on the scale together. This is a great feature if you need a scale with cumulative weighing for compounding ingredients or check weighing.

Checkweighing Make sure ya get your weights just right with this Ohaus scale. When ya weigh in this mode, you can set weight limits for the stuff you're weighing. If your sample weight is too low or too high the scale will surely let ya know.

1 YEAR MANUFACTURER'S WARRANTY! When ya buy this NV4101 AM Navigator you'll need to head on over to the Ohaus website and register it to receive your one year warranty.
