These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All have a threaded male shaft for connecting additional attachments. Activate the peak-hold setting to retain the highest reading on the display.

The large dial makes these gauges easy to read. They measure tension force as well as weight. All come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. 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.

Apply your load directly to the top of these gauges to measure compression force. Mount them horizontally or vertically to your equipment for frequent testing. They come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Activate the peak-hold setting to retain the highest reading on the display.

Use the included Windows-compatible software to upload measurement data. These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All have a threaded male shaft for connecting additional attachments. The tare function lets you reset the scale to zero. Activate the peak-hold setting to retain the highest reading on the display.

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.

Measure the torque output of torque wrenches, screwdrivers, and other hand tools to ensure they deliver the right amount of torque—and check your results on a digital screen. Cycle through four units of measure on the screen, then set it to display real-time or maximum torque. These testers have a keyless chuck that's similar to a standard drill chuck: insert the tool you're measuring and tighten the chuck by hand. They can also be used to measure the torque consistency of small rotating parts, such as motors, potentiometers, and encoders.

Testers with calibration certificate with test data traceable to NIST include the test measurements that confirm accuracy.

The tester's memory keeps track of up to 999 different measurements. Use the USB cable and software download link (sold separately) to transmit, store, and analyze test data on a computer. The software stores time, date, and torque measurement values that you can import into Microsoft Excel.

To use the tester on external power, add an AC adapter (sold separately) and attach it with the USB cable (sold separately with the software).

For large and oddly shaped items, use a testing fixture (sold separately). Testing fixtures fit inside the tester's chuck and have four clamping pins that allow you to hold objects as wide as 2 1/4".

For handheld use, the display fits inside the back of the tester. To use the tester on a flat surface, remove the display from the back of the tester. For additional stability, mount the tester onto a testing stand (sold separately). Testing stands have four pins that fit inside the tester to anchor it, a handle for leverage, and mounting holes for permanently securing the stand.

Measure the twisting force needed to tighten tops, loosen lids, and turn potentiometer knobs or valve wheels. These testers are often used to fine-tune automated capping machines, or to help design bottling and packaging processes. An adjustable clamp holds your container in place while you open and close the cap. Four posts on the clamp can be moved to fit objects of any shape.

Store your data on the included Micro SD card, or send it to tablets and computers using Bluetooth or a USB connection. Connect to a controller using the I/O cable to control other devices dependent on torque readings. The RS232 cable lets you send data directly to your printer to create reports or labels.

Choose a torque range that is greater than the force you will be testing. These testers have overload protection, which prevents damage to the measuring system if you accidentally exceed the torque range.

Testers with a calibration certificate with test data traceable to NIST adhere to strict guidelines for accuracy.
