GPR-1500 PPM User's Manual GPR-1500 N User's Manual Datasheet
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.
