Wall Mounted Easy To Maintain PPM Oxygen Measurement
Features
Measurement ranges 0 to 10ppm up to 0 to 1% O2
Can be calibrated with ambient air.
General purpose or intrinsically safe (ATEX) models
Fast recovery from exposure to air
Can measure in pure CO2 with XLT sensor
Two alarms with GPR-1500 A analyzer model
A wall mounted oxygen analyzer in a NEMA enclosure, suitable for indoor or outdoor. This single channel oxygen monitor is supplied with a stainless steel O2 sensor housing for trace oxygen gas analysis in safe as well as hazardous areas where ATEX approval is needed. The low detection limit of 0.05ppm allows a minimum oxygen measurement range of 0 to 10 ppm O2. Ideal for clean gas applications and when used with the XLT oxygen sensor type it allows measurement in pure carbon dioxide. The Analytical Industries long-life oxygen sensors are maintenance-free sealed electrochemical cells that don’t need top up of electrolyte and can be exchanged in few minutes.
