Washdown Go/No-Go Bench-Top Scales

Check for quality and consistency among packages, parts, and other objects in areas that are frequently washed down. These scales are IP and NEMA rated, so they seal out water and dust. Also known as check weighers, they alert you when items are outside of a set weight range. The stack light uses three colored lights: one for too heavy, one for too light, and one for when items are good to go. An audible alarm also signals when items are outside your weight standard. Exact measurements appear on a bright, backlit LCD display. Mount the display to the included column to position it where it’s easiest to see.

Press the tare button to reset these scales to zero when using a container to hold small items. To print or transfer data to a computer, connect an RS-232 computer cord (not included) to the scale's DB9 port.

Washdown Legal-for-Trade Bench-Top Scales

IP69K and NEMA 4X (Shown with Removable Column)

IP rated for washdowns and use in dusty and wet environments, these scales are NTEP approved to weigh materials that are sold by weight. All have a check weighing mode that alerts you when items fall outside a set weight range, an accumulation weighing mode to keep a running total of all the items you’ve weighed, and a tare function that resets the scale to zero after placing a container on the platform. A large LCD display with a touch keypad makes it easy to read and select measurements, even when wearing goggles and gloves.

Scales with a 10-lb. capacity or lower are better for measuring lighter loads more precisely than our scales with higher capacities.

To handle the most rigorous washdown applications, IP69K-rated scales protect against dust and high-pressure, high-temperature washdowns. They’re also NEMA 4X rated for use outside or in mildly corrosive environments. If you accidentally place a heavy object on the scales, they’re durable enough to handle it; they withstand a load up to 1,000% of their capacity. The display on these scales is detachable, so you can mount it to the column, on the wall, under a counter, or in front of the scale. To print or transfer data to a computer, connect an RS-232 computer cord (not included) to the scale's DB9 port.

Washdown Legal-For-Trade Floor Scales with Remote Display

Scale

Ramp

These scales are NTEP approved as legal for trade and have an IP69K rated load cell for use in washdown environments. They withstand exposure to dust and moisture, including the frequent high-pressure, high-temperature washdowns commonly used in outdoor industrial environments, food processing facilities, and chemical plants. Plus, the scale-to-display junction box meets NEMA 4X standards for protection against washdowns and corrosion.

Also known as platform scales, these have a low profile so you only need to lift heavy objects 3" off the ground. Their stainless steel construction and a ribbed structural underside give them the necessary support to weigh thousands of pounds at a time. To keep items in place, a diamond tread on the platform provides slip resistance. The load cells in these scales are FM approved, so they’ve been tested for quality and safety by Factory Mutual.

Subtract the weight of a container with the tare function to weigh only the material inside. Use the counting mode to keep a running tally of how many items are on the scale.

Mount the remote display at a distance on a workstation, column, or wall—the connecting cable is 22 feet long. The backlit display features 1"-tall digits for easy reading.

Install optional ramps to slide or wheel heavy loads onto scales. If you install two ramps, they must be on opposite ends.

Large-Capacity Digital Tension Force Gauges with Scale

Measure tension force as well as weight. These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All are NEMA 4X rated for protection from dust, water, and mild corrosives. They can be manually reset to zero and have a peak-hold setting that retains the highest reading on the display when activated. Also known as dynamometers.
