Tetso 312-2 precision pressure gauge

Specs:
When installing or testing a gas heater, pressure measurement is of vital importance. Differential, environmental, gas flow and gas outlet pressures must be checked with extreme care due to the level of danger.
The data offered by this meter is highly accurate. It allows a measurement with the resolution of 0.01 hPa. Its use is very simple, the screen is easy to read, with large and clear numbers. It also indicates the time in the reading. Another advantage is that it can be used with a portable printer from Testo, to be able to leave the data printed at the time of reading. The latter is necessary when reporting data.
An alarm can be set on the same meter (visual and audible) that warns when optimum levels are not reached. In addition, it should be noted that it is authorized according to DVGW.
It works with a 9V square battery, being able to use the rechargeable model of the same brand. For its best conservation, there is the TopSafe case with support that protects it from impacts and dirt.
Probes are necessary to determine the values. The ideal complement to the meter is the Pressure Set with a shooting probe that is accompanied by two silicone tubes of 4 and 6 millimeters in diameter.
