Mini Gas Meter - Tetra
mini gas meter with ATEX approval

The great family of Tetra products was extended by the excellent Mini Gas Meter. The Mini Gas Meter - Tetra has an extremely solid finish, a small format and is very simple to handle. This gas meter is resistant to meteorological inclemencies and the hardest surrounding conditions, plus it can be used in heavy industry (for example in the construction of tunnels). A great advantage is its simple handling with a single button that you are able to press even when wearing gloves. The Mini Gas Meter measures oxygen, toxic gases and inflammable gases and shows the measurement  values on a graphical screen with backlight where the operative mode is also indicated. The rubber surface of the housing of the Mini Gas Meter makes it resistant to shocks and vibrations. IP 65 and 67 protection makes it dust and water resistant. Its solid format is completed with a stainless steel holder. In case of danger, the Mini Gas Meter has a visual alarm in the form of red and blue flashing luminous diodes and acoustic alarm which emits a high-pitched sound. With the rechargeable lithium-ion battery it's possible to operate the device for 18 hours.

Calibration

View of the top of the gas meter TETRA/LCD

The calibration of the apparatus can be made regularly by means of the automatic function of calibration or PC with the Windows compatible software.
You can also send the gas meter to us (according to the internal ISO manual  of the company) for its maintenance and recalibration (i.e. 1 or 2 times a year). The gas meter will be disassembled, cleaned and recalibrated.
We will inform you if the sensor can not be recalibrated or if its operation life has already finished. You will be able to find replacement sensors in our online shop.
