2280A Four-channel H2S Gas Monitor

The 2280A is a system for continuously monitoring H2S gas concentrations in four locations. The system consists of up to four remote mounted sensors and a solid state controller. The controller consists of four independent channels, each having its own circuitry. With a digital display, the 2280A shows hydrogen sulfide gas concentrations in ppm (parts per million) in the ranges of 0-20, 0-50, or 0-99 ppm for each channel.

  • 4-20 mA Outputs
  • Digital Displays
  • Common or Discrete Relay Output Options
  • Safe and Easy Calibration

DT210 Eight-Channel Readout/Relay Monitor

The DT210 is an eight-channel Readout / Relay Module designed for use with up to eight of our remotely located H2S Intelligent Sensors. The front panel contains a digital display that indicates 0-20 ppm (parts per million), 0-50 ppm, or 0-99 ppm of the hydrogen sulfide gas monitored by the Intelligent Sensors.

  • Compact Design
  • Large digital display
  • LED Readouts for each channel
  • Common Relay Outputs
  • Safe and easy calibration

2602A Zero Two Series H2S Control Module

The 2602A is a single-channel H2S Control Module that has been designed to monitor H2S in parts per million (ppm) levels and provide status indication and alarm outputs. Microprocessor-based electronics allow all options to be user selectable through front panel interface (mode / select switch and digital display). The digital display on the 2602A indicates hydrogen sulfide gas concentration, fault codes, calibration cues and setup options. Other features include LED indications of status, relay outputs for fault, low alarm and high alarm, and serial communications ports.
