NLB-CO2+RH+T-5-MRF |
The NLB-CO2+RH+T-5-MRF is a wireless room
sensor and is intended for continuous
monitoring of indoor air quality and for
effective control of ventilation (HVAC)
systems according to the current air quality.
The sensor monitors the concentration of
carbon dioxide (CO ), relative humidity (RH)
2
and air temperature (T). It is used in
households, offices, schoolrooms, shopping
centers, restaurants, fitness centers,
commercial buildings, etc. for efficient control
of ventilation systems.

Description
The measuring of CO is based on an optical principle
2
(NDIR) using advanced optical chamber. Built-in auto-
calibration function ensures excellent long term
stability and accuracy.
Measurement of the relative humidity is based on the
principle of capacitive polymer sensor.
Individual quantities (CO

receiver either via RS485 serial interface with Modbus
communication or via two analog outputs (CO
RH).
The sensor efficiently controls ventilation systems,
based on current room air quality.
Low battery power is indicated by a built in LED
indicator.
