Pressure; Long-Term Exposure To High Gas Levels - Thermo Scientific Odalog L2 Series User Manual

OdaLog® L2 – Gas Logger User Manual
In high RH environments (over 90%), a time-in/ timeout ratio of two days "in" and two days "out" is
recommended. This ratio allows the sensor adequate time in a "normal air" environment to "dry out" and
return to its normal operational state.
Under these conditions, regular physical checks and sensor calibration are essential; an after-use "span
check" is recommended for such environments (see Section 9.8).

7.2.3. Pressure

Sensors may exhibit the effects of changes in pressure. For example, an increase in pressure may result in
an increase in gas reading. For this reason, we do not recommend this sensor for use in pressurised
applications.

7.3. Long-Term Exposure to High Gas Levels

It is possible for some electrochemical sensors to "drop off" in reading when exposed to high levels of gas
for extended periods. Therefore, a "pre-use" and "post-use" span check may need to be carried out as
described in Section 9.8.
