Sensor care for the testo 320 and 330

Electrochemical cells need an annual check.

These cells react with the gas they measure. Their response gradually changes as the chemistry is used, and heat, moisture, contamination or long storage can make a cell drift or stop responding.

Calibrate annuallyVerify response and document the result before a reading is used for a safety decision.
Service when response fallsQRM checks the sample path, filters and cell condition and identifies replacement needs.
