The DPG4000 series has been replaced by the DPG210 series . The new DPG210 series has premium features, the same high accuracy, and a lower price point. Many ranges are in stock, available for immediate shipment.

The DPG4000 takes the concept of a test gauge to a new level. It combines the accuracy of digital technology with the simplicity of an analog gauge, delivering performance, ease of use, and a feature set unmatched in the pressure measurement world. Setup of the DPG4000 is fast and straightforward, involving a menu driven display with minimal text and intuitive functions. The gauge is simple enough to be used anywhere in the world, without the need for multilingual displays.

It also incorporates a built in data logging function which when combined with the DPG4000-SW software allows it to function as a high performance pressure data logger. The unit can store up to 8500 data points which can then be downloaded and stored in a variety of formats including ASCII text, comma delimited text, and Micorsoft Excel Spreadsheet using the software. The software can also be used to configure a wide range of settings including logging interval, number of data points per run, capture mode and type of data.

Rated 5 out of 5 by from Superior Quality Great quality gauge with loads of features. The technical support was great and helped me find the perfect gauge for my testing setup. Would highly recommend this product to anyone.

Rated 3 out of 5 by from Weak link - aluminum fitting We have 3-4 of the gauges. They are good gauges, but there is one flaw that cannot be overlooked. There is a weak aluminum fitting that connects that gauge to the process. On a couple of gauges, this fitting has cracked on us while installing, rendering the gauge useless. Recently, we had this fitting break during a 2,000 psi pressure test. We have declared this gauge unfit for use in our organization. Omega should reconsider this design.

Rated 1 out of 5 by from Do not buy this gage Gage is being discontinued. No serial cable available despite description suggesting it is. Software cost more than gage:(

I recently purchased this gauge based on it having an RS232 capability. I see the cable is no longer available for purchase. Is it possible to get the pin out and I can make my own RS232 cable?

Asked by: chris1977
9 pin D connector on one end of cable. 3 segment phone jack on the other. Tip of jack connects to pin 2 on connector (receive). Center of jack connects to pin 3 on connector (transmit). Bottom segment of jack connects to pin 5 of connector (ground)
