Duct & Rough Service Carbon Monoxide Sensor

NSB-CO-V-BB (rough service CO sensor)
NSB-CO-D-BB (duct CO sensor)

The Carbon Monoxide (CO) Sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. The duct unit samples duct air using an aspiration tube. This rough service unit features a ventilated enclosure and is ideal for parking ramps, equipment rooms and warehouses.

Rough Service Carbon Monoxide Sensor

NSB-BBV-CO

The Carbon Monoxide Rough Service Sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. It features a ventilated enclosure and is ideal for parking ramps, equipment rooms, and warehouses.

Carbon Dioxide (CO₂) Duct Sensor

NSB-ACD05-D-BB (single beam unit)
NSB-DCD05-D-BB (dual channel 24/7 unit)

The Carbon Dioxide (CO₂) Duct Sensor is an accurate and reliable way of incorporating demand controlled ventilation. It measures CO₂ in ranges of 0 to 2000, 0 to 5000, 0 to 10000, and 0 to 50000 ppm with a field-selectable output of 0 to 5 or 0 to 10 VDC.

Nitrogen Dioxide (NO₂) Duct/Rough Service Sensor

NSB-NO2-V-BB (rough service NO₂ sensor)
NSB-NO2-D-BB (duct NO₂ sensor)

The Nitrogen Dioxide (NO₂) Rough Service Sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. The NO₂ Duct Unit Sensor samples duct air using an aspiration tube. The rough service unit features a ventilated BB box and is ideal for parking ramps, equipment rooms and warehouses.

Refrigerant Leak Detector

NSB-RLD

The Refrigerant Leak Detector Sensor measures the amount of R404a, R410A, R134A, and/or R22 present. This sensor measures leaks and spills; it is not intended for critical ppm measurements. The sensor is temperature compensated for an accurate and reliable measurement.

Water Leak Detector

NSB-LDT4-PS-BB (water leak detector w/internal probe sensor)
NSB-LDT4-RS10-BB (water leak detector w/remote spot sensor)
NSB-LDT4-RR*-BB (water leak detector w/water rope sensor (10', 25', 50' or 100' rope))

The Water Leak Detector is designed to sense the presence of water and alert a central monitoring system of the potentially destructive situation. Upon water detection, an alarm relay changes state, and a local red LED illuminates. The transmitter can be set for latching alarm or non-latching alarm with normally energized or de-energized operation. An optional remote water sensor is available for small inaccessible locations such as AHU pans or under floor water detection.
