- Choice of oxygen levels as % saturation or concentration (mg/l)
- Measurement, compensation for and display of air pressure in hPa
- Rugged, splash proof, membrane keypad and front facing (IP 54) for use in the field and in wet environments
- Simple, straightforward operation
- Continuous display of minimum and maximum values
The Oxygen Meter OX 22 is a portable, battery-operated meter for combined measurement of oxygen levels as % saturation or concentration (mg/l), air pressure and temperature. It offers a number of useful functions:
After switching on the polarisation period begins automatically: it is shown on the display as seconds elapsed. This process can be halted or shortened by key presses.
The LCD display can be switched between readings for oxygen concentration (mg/l), oxygen saturation (%) and air pressure (hPa). Temperature is a permanent built-in feature on the display. The facility for continuous log-ging of minimun and maximum values which can be viewed at any time without interrupting measurements.
A HOLD function which freezes the display at the current reading.
Automatic switch-off if the instrument has not been used for 30 minutes.
The instrument comes as a complete kit including an oxygen electrode with integrated temperature sensor and accessories in a carriying case.
