Temperature Probes & Sensors

Temperature probes and sensors encompass a broad range of instruments designed to measure temperature in contact with solids, liquids, gases, and surfaces. This category includes thermocouple probes, RTD probes, thermistor sensors, and specialty probes for measuring dewpoint, surface temperature, and process media. Probes are available in a wide variety of tip geometries, insertion depths, connector types, and ingress protection ratings to suit diverse industrial and laboratory requirements.

Leading manufacturers such as Testo, Wahl Instruments, and AMETEK-JOFRA offer solutions ranging from flexible hand-held field probes to precision laboratory sensors and application-specific kits. Probes are used with temperature meters, data loggers, calibrators, and process controllers, typically in interchangeable formats for compatibility across multiple readout devices. Key selection criteria include accuracy, response time, temperature range, chemical compatibility, and environmental ruggedness.

Typical Applications

HVAC commissioning and building energy performance verification using immersion and duct probes
Food safety and cold chain monitoring with waterproof, NSF-compliant surface and penetration probes
Industrial process control using high-temperature mineral-insulated probes in petrochemical and power plants
Calibration laboratory reference measurements using precision PRT and SPRT probes
Dewpoint measurement in compressed air systems and industrial drying processes
Pharmaceutical and cleanroom environmental monitoring with traceable sensor kits
