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.
Features - Non-intrusive, one-person automatic calibration via single external pushbutton
- Equipped with three (3) 5-amp relay contacts--two (2) alarms and one (1) fault
- Normally energized/de-energized and latching/non-latching alarm relay functions
- Two (2) backlit alphanumeric LCDs advise all gas
hazards and operational faults, as well as instrument
and sensor statuses - Auto zero and auto span functions
- Backlight in low light (auto) and in alarm (auto)
- Extensive fault diagnostics
Self-Test - Full function sensor integrity test (daily; auto)
