Greisinger GLF 175 Air Temperature Probe, Pt1000, -70 to +200 °C, 175 mm, 1 m Cable, Mini-DIN 604697

Accurate air temperature measurement in demanding environments requires a sensor that combines precision, durability, and compatibility. The Greisinger GLF 175 air temperature probe addresses this need with a Pt1000 platinum resistance sensor housed in a stainless steel tube, delivering reliable readings from -70 to +200 °C. Its 175 mm probe length and 4 mm diameter allow insertion into ducts, chambers, and other air or gaseous media, while the 1 m PVC cable with 7-pin Mini-DIN plug connects directly to compatible Greisinger handheld instruments.

Who is it for

This probe is intended for HVAC technicians, laboratory personnel, and industrial maintenance teams who need to monitor air temperatures in ventilation systems, climate chambers, or process environments. It is suitable for users who already own Greisinger GMH series measuring devices and require a dedicated air temperature sensor with a wide operating range.

Tips

For best accuracy, allow the probe to equilibrate to the measured air temperature before recording. Ensure the Mini-DIN connector is fully seated and protected from moisture; the connector is rated IP40 and should not be exposed to splashing liquids. When measuring in ducts, insert the probe tip into the center of the airflow for representative readings.
