Digital pressure chart recorder


Choose accuracy needed for gauge (0.05%, 0.1%, or 0.25% FS) and add TP option for temperature.


All gauges come with NIST data and certificate including temperature measurement with readout to 0.1°F/°C.


Add software to create full blown custom test reports. This includes the ability to combine files! 

Download the software via the Google Drive link or zip file. No restrictions. You may need admin rights depending on security settings. This is the full version, if gauge is activated it will work. If not, you will be limited to 100 samples.

Hydro Data Management Screen Shot_2-4-20

Works with all ETG and HTG pressure products for graphing pressure & temperature. Included standard with the HTG Product Series. Digital pressure chart recorder. 

Do you need an easy and cost effective way to monitor temperature and pressure for testing pipe or pressure vessels? Add ambient temperature monitoring to any ETG gauge and produce professional reports with the Hydro Data Management software. Ideal for most ASME B31.3 Process Pipe Testing that is typically done with analog gauges and hand written reports. Meet the testing and record requirements of CFR 49 Subpart J under 192.513 and 192.517 for Transportation of Natural and Other Gas By Pipeline. Replace several analog gauges and chart recorders with one HTG to save on maintenance and calibration costs. Monitor Min, Max, Alarms, and Live pressure on your phone with the new Hydro App while recording data. Even perform a leak test while recording data to troubleshoot or soap the connections and welds. 

Create secure files with date and time stamp directly into an Adobe .pdf file. Upload the results from the gauge with a standard USB cable. Save time, money, and create professional reports by eliminating the need to work in Word, Excel, or other programs to piece things together. This includes the ability to add files from other sources to create one report. Pick and choose the order in which the pages appear. Print the file and have the test witness sign off on the hard the copy record for paperwork compliance.
