Dillon Dynamometer

When you need to measure the pressure in suspended weight between two objects, a conventional mechanical Dillon dynamometer and other instruments from this brand will suffice. It will show the tension force between two attached shackles in particular. It uses a needle that points to the numerals on the device's surface to provide an accurate reading. For decades, our construction sector customers have relied on Dillon devices to determine what works best for their projects. We guarantee that any development project will be considerably easier to accomplish with the correct tools.

R.D. JACOBS COMPANY is your source for the best Dillon dynamometers.

Wireless Dynamometer

The digital version of the wireless dynamometer is popular for its easy readability. Just because it’s computerized doesn’t mean it’s any less capable than the mechanical version. You’ll be able to switch through all the different functions to get the information you need using very clear digital displays. The wireless feature makes it much easier to get the readings you need from wherever you’re standing.

Investing in a wireless dynamometer will make way for more convenience in your project. It can also make the job more efficient when it’s easier to monitor the weight and tension force at any point and time. Stay safe and go wireless.
