  • GasPost II RS485

    The Acme GasPost II toxic gas sensor/transmitter measures CO and NO2 gas concentrations in enclosed areas and transmits its readings to a CEL-series monitor/controller over an addressable RS-485 “Daisy-Chain” sensor network.

  • RS485 RelayPost

    The Acme WR Series Remote Relay Module operates within a CEL-LS RS-485 gas detection network, acting as an addressable output to the CEL Control Panel. Each WR Relay Module provides 8 relays for the indirect activation of fans, louvers, and other kinds of peripherals, at programmable set points.

  • Explosion Proof Gas Post

    The Acme Combustible gas sensor-transmitter measures the concentration of the target gas in an enclosed area and produces a proportional analog output signal. The Acme 40-ST Combustible Gas sensor is explosion proof. The enclosure of the sensor-transmitter is a explosion proof enclosure.

  • Quadset Refrigerant Gas Monitor

    The Acme Quadset Refrigerant Gas Monitor is designed to detect refrigerant leaks in enclosed areas. The Monitor utilizes a sophisticated NDIR sensor specific to any one of the commercially available refrigerants.
