Description
Precise oxygen and temperature measurement
The instrument measures the oxygen content in a range from 0 % to 30 % and simultaneously captures the ambient temperature. By using high-quality sensors it provides reliable data for evaluating the oxygen concentration in closed rooms or industrial environments.
Efficient data management
The device has an integrated data hold function, with which current measured values can be frozen on the display. In addition, it automatically saves the maximum and minimum values (MAX/MIN), WAS simplifies the documentation of peak values during a series of measurements.
Clear 7.11 cm (2.8 ") LCD color display
The large LCD display allows easy reading of the measuring data. Thanks to the background lighting it is also possible to use it without any problem in poorly illuminated work areas or in dark shafts.
User-friendly handling
The operation is intuitive via a clear keypad. An automatic switch-off function saves battery capacity, if the device is not used actively for a longer period of time.
