A wall mounted analyzer in a NEMA enclosure, suitable for indoor or outdoor use, offering a basic 4-20 mA output signal optional alarm relays. Ideal for clean gas applications where basic sample handling is all that is required. Available in configurations for safe and for hazardous area installations (intrinsically safe).

  • Multiple user-configurable measurement ranges available
  • 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
