Tenmars TM-186 CO2 Meter and Temperature

Tenmars TM-186 Maintenance

a Do not use the meter in an environment with severe change; do not store the unit in an environment with high temperature, high humidity, and high vibration. Take the battery off if the meter has not been used for a long period of time. The Diode temperature probe is used to measure temperature and the capacitive humidity sensor is used to measure take humidity. The thermocouple and humidity sensor will start aging under the influence of oxidation, reduction, corrosion, pollution, vaporization, diffusion or other metallurgy. The aging process will affect its precision seriously. Cleaning and inspection of temperature probe: The smoke, coal, dust, grease attached on the protective tube oftemperature probe will slow down the heat conduction of the thermocouple and cause measuring error. Therefore, it should be cleaned periodically. The metal coating of thin thermocouple should be replaced properly upon the occurrence of corrosion. o Cleaning and inspection of humidity sensor: The smoke and dust attached on the humidity sensor will slow down the function of humidity sensor and cause measuring error. Therefore, it should be cleaned periodically. Blow off the dust with mild compressed air instead of water or alcohol. The aluminum plate inside the humidity sensor should be replaced upon the occurrence of corrosion
