• Brand: testo

How to use

Connect the Type K probe to a compatible measuring instrument or data logger that accepts Type K thermocouples, ensuring correct polarity. Place the probe in firm contact with the surface or medium to be measured, allowing sufficient time for the sensor to reach thermal equilibrium before recording readings. For process checks or inspections, perform measurements at several points as required to verify uniformity or identify deviations.

Usage recommendations

To maintain measurement accuracy, avoid mechanical strain on the probe connections and store the probe in dry conditions when not in use. When measuring in environments with rapid temperature changes, allow time for the probe junction to stabilize and verify readings against a reference if high precision is required.
