The self-contained GasPoint transmitter with internal alarm relays provides a 4-20 mA output signal and can be connected to any control system (DCS, PLC or controller). With advanced sensor technology and microprocessor-based operation, GasPoint provides continuous monitoring for H2S, CO or combustibles.
GasPoint's ease of use and cost of ownership advantages make it the ideal fixed system transmitter. No junction box connection is required, and sensors can be changed at will. GasPoint will recognize the type of sensor installed, test it and reset itself to the corresponding sensor type.
GasPoint monitor comes with 3-wire, 4-20mA gas transmitter with advanced microcontroller-based circuitry and plug-in, smart sensors. Instrument warranty is 2 years, non-prorated. Sensor warranty is 2 years, full replacement warranty.

Full Review
- Display advises gas type monitored, continuous (%LEL, %v/v or ppm) readout of gas concentration, alarm level and type encountered, automatic daily self-test sensor failures, sensor replacement and sensor expired indications, and when to apply gas during calibration
- All plug-in sensor assemblies are field-interchangeable
- Full function sensor integrity test (auto) continuously advises gas sensing ability and life ended
- Non-intrusive, one-person calibration with auto zero and auto span
- Equipped with three 5-amp relay contacts—two gas alarm relays (Low/High) and fault alarm
- Field-selectable normally energized/deenergized and latching/non-latching alarm relay functions
- Two backlit alphanumeric LCDs advise all environmental and gas hazard conditions as well as instrument and sensor status
- Remote toxic/oxygen sensors can be installed over 3,900 ft./1,100 m away; combustible sensors over 1,550 ft./475 m
- Alarm setpoints displayed on demand—simply press the external button
- Field programmable alarm levels
- Extensive fault diagnostics
- 2-way digital communication using MODBUS module
- No junction box connection required
- Daily sensor integrity test (auto) monitors sensor operation, length of time sensor has been in service and advises when sensor requires replacement
- GasPoint allows you to set or change calibration time and gas alarm setpoints in the field
- Select or modify the measuring range using a simple dipswitch
- The optional plug-in MODBUS expansion module provides an addressable communications interface (1-247)
