BW-M5-PID-RS Honeywell BW NH3 Sensor PID for BW GasAlertMicro 5BW Manufacturer Part Number: SR-Q07At concentrations over 4,000 ppm, the PID sensor will display OL and the LEL sensor takes over, giving you 3-100% LEL readings for the explosive-levels decision making range. Most response trainers recommend leaving the area at 10% LEL. Additionally, the PID sensor has an extremely fast response time and is useful for finding small ammonia leaks. Think of it as an "electronic sulfur stick"?. Refrigeration technicians will find this a useful tool for locating difficult-to-find leaks by "sniffing" around valve packing, sight glasses, shaft seals, etc.
