Are you missing out?

ESI have manufactured produced thousands of USB transmitters since we first developed the product over

10 15 years ago.

The Genspec Dynamic USB Transducer, or the GD4200, is a digital pressure measurement system, comprising

of a pressure transducer and software, which can be up and running quickly and easily very quickly without

the need for wiring, separate power supplies or signal conditioning instrumentation. Live pressure

measurement readouts are displayed on the screen of your laptop or PC. Whether you are looking to

perform test and calibration, spot checks or local, direct monitoring the GD4200-USB is the most convenient


The software specifically has grown and evolved tremendously over the years, as we have worked closely

with our customers to incorporate the features they wished for want and need. Four years ago we undertook

a major upgrade, and ESI-USB Version 2 was born. It has continued to develop with more fine tuning and

unique features ever since. We have found customers are still using the original version 1 software, but are

missing out on all the benefits of the latest version 2.

Version 2 has an inbuilt leak testing feature, the ability to rename sensors, show 16 sensors on the monitor

screen at once, set a delayed start/finish time, compare sensors (create a virtual Differential Transmitter!)

and overall refined screens and functions. It also has an auto-update facility, meaning that any future

changes won’t be missed. Version 2 can be downloaded for free from our website.

So, if your software looks like this…

Then you’re missing out on this…

And this…
