High Temp. Type K Immersion Thermometer Probe – Sper Scientific Direct

The primary difference between Type J and Type K thermocouples is the measuring range, and the sensitivity. Type K is the most common general purpose thermocouple with a sensitivity of approximately 41 μV/°C. A wide variety of probes are available in its −50°C to +900°C / -58°F to +1652°F range. Type K wire color standard is yellow (+) and red (-). Type J has a more restricted range of −50 to +400°C, but higher sensitivity of about 50 μV/°C.

Sper Scientific 800060 Small Type K Immersion Thermometer Probe

Features. Monitor RH & temperature inside an environmental chamber or clean room without opening the door. Place the weatherproof (IPX3) sensor outdoors in green houses warehouses air ducts and other hard to reach places and continuously monitor ambient RH & temperature from a remote location. The wireless sensors broadcast to the monitor from up to (30M) away without obstructions using a wireless RF signal.

Sper Scientific 800062 High Temp. Type K Immersion Thermometer Probe

When the highest accuracy is required - even at very low temperatures and under changing environmental conditions. Platinum resistance temperature detector (RTD) probes offer the highest accuracy and stability even at very low temperatures and under changing environmental conditions. Results are displayed in °C or °F on a large backlit LCD along with Max/Min readings.
