IR SENSOR FIXED GAS DETECTOR

These single-gas, multi-gas, PID monitors, controllers, and wireless alarm bar can be installed to

provide continuous, always-on monitoring for toxic gases and gamma radiation.

no false alarms utilizing stable, field-proven sensor technologies

Highly selective for specified target Gas

No zero drifts with changes in ambient conditions

Self-Calibration adjusts span based on sensor life curve

Non-Intrusive field Calibration using magnet

LCD display: 12 characters x 2 lines. Provides user interface with magnetic switches

Not affected by temperature -40 deg. C to +50 deg. C

Offsite sensor calibration with sensor embedded memory chip

Peak value, 15-min. , Remaining Sensor Life, Replace Sensor indication and number of days since last gas calibration

Optional Relay Module in same enclosure with low, mid, high and fault relays; rated 10 Amps. Gas alarm relays can be programmed latching or non-latching, energized or non-energized, time delays
