Economical, general purpose gas detector or controller. These detectors provide an early warning
of hazardous concentrations of Ammonia, Propane, Methane, Nitrogen Dioxide, Hydrogen and other gases.

Space ABS enclosure

Wall Mount Explosion Proof
Available for CO, Toxic,
and Combustible Gas Detectors
Electrochemical and Catalytic
sensors only.

To sense and transmit gas concentrations to any compatible electronic analog control, DDC/PLC controller or automation system. Also provides a visible and audible alarm for high concentrations of gas. Some areas in which the unit may be used include: parking and maintenance garages, ventilation systems, hazardous storage areas, factory work areas, repair facilities, mines and tunnels, arenas and swimming pools, chiller rooms.

  • Monitors Toxic and Combustible Gases
  • Field replaceable Sensor Module allows for use of spare modules and/or factory calibration without down time
  • Optional LCD for displaying level
  • Optional Audible Alarm
  • Microprocessor based (12 bit accuracy)
  • System configuration saved in non-volatile memory
  • Optional relays can be configured with normally open and normally closed contacts
  • Please note, calibration will be required annually and may be necessary more frequently depending on the nature of the application.
