Temperature Sensor testo 0602 0646 Type K probe, temperature range -50 to +250°C

testo 0602 0646 is a Type K temperature sensor designed for contact measurement across a wide temperature range from -50 to +250°C. This probe is intended for reliable temperature monitoring and measurement in HVAC, laboratory, food processing and industrial environments where accurate and stable readings are required for process control, troubleshooting and routine inspections.

Advantages

The Type K probe construction provides broad-range thermocouple measurement capability with stable output suitable for continuous monitoring and spot checks. Its specified measurement range of -50 to +250°C covers common needs in heating, ventilation, refrigeration, laboratory testing and food industry tasks. The sensor is compatible with instruments that accept Type K inputs, facilitating integration into existing measurement workflows.

Key specifications

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.

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.
