GENERAL
TR-EC-CO is a sensor designed to measure the concentration
of carbon monoxide (CO) and TR-EC-NO
concentration of nitrogen dioxide (NO
etc. The sensors are of electrochemical type with good
selectivity and high accuracy even at low concentrations.
The detectors provide a linear output signal (4..20mA or 0..10V
DC) proportional to the concentration of carbon monoxide or
nitrogen dioxide.
Choice of output signal is controlled by the jumper (see PCB
layout) with mounted jumper gives 0..10V DC signal output.
Standard measuring range is 0-300ppm for the TR-EC-CO and
0-20ppm for the TR-EC-NO
.

MEASURING RANGES AND ALARM LEVELS:
Maximum acceptable gas concentrations are regulated by
hygienic, safety, environmental and construction directives.
Relevant alarm levels depend on application.
Please check local standards and regulations for relevant
values.
LOCATION / INSTALLATION
TR-EC-CO should be mounted on the wall approx 150 cm
above floor level and TR-EC-NO
cm above floor level.
