What is an NTC sensor and why is it used in this probe?

NTC stands for Negative Temperature Coefficient. An NTC thermistor is a type of resistor whose resistance is inversely proportional to its temperature; as temperature increases, its resistance decreases. This characteristic makes NTC sensors highly sensitive and accurate for temperature measurements, particularly across the specific range this probe is designed for, providing reliable data for HVAC and industrial applications.

What does the IP67 protection class signify for the probe's durability?

IP67 is an International Protection Marking, indicating that the probe is 'dust tight' (the '6') and protected against temporary immersion in water up to 1 meter for 30 minutes (the '7'). This ensures the probe's internal components are well-protected from dust and moisture, making it suitable for use in demanding and wet environments common in HVAC and industrial settings.

What types of materials or environments can this immersion/penetration probe measure?

This versatile probe is specifically designed for accurate temperature measurement in three primary types of environments: liquids (such as water, oils, or refrigerants), pastes (like sealants, gels, or food products), and air. Its robust design and precise NTC sensor make it ideal for broad applications where contact temperature measurement is required.
