Handy Atmosphere

The Handy Atmosphere is a hand held meter designed to measure oxygen in gas.

It can be used to measure the low oxygen content of packaging gas, the oxygen content of the air and the purity of oxygen gas from oxygen generators and the like.

The Handy Atmosphere is a hand held meter designed to measure oxygen in gas. It can be used to measure the low oxygen content of packaging gas, the oxygen content of the air and the purity of oxygen gas from oxygen generators and the like.

 

Signal processing is performed using a microprocessor, which gives a number of advantages.

 

Just as with other Handy instruments you can simply switch on and measure, but the use of microprocessor technology enables measurements to be supported by a range of advanced functions designed to make things even easier for you:

 

Automatic Calibration
Choice of Language
Oxygen, temperature, barometric pressure.
Automatic self-check
Automatic Probe Check
Barometric Pressure Compensation
Extremely long battery life
