Greisinger GLF 401 MIN Temperature and Humidity Air Probe with Pt1000 Sensor and 1m Cable 116480

Accurate climate monitoring in air and non-aggressive gases requires a reliable sensor that connects directly to your handheld measuring device. The Greisinger GLF 401 MIN air probe provides precise temperature and humidity readings with a Pt1000 element and capacitive humidity sensor, eliminating guesswork in HVAC, laboratory, and storage applications.

Who is it for

Technicians and engineers who need fast, repeatable air measurements with a Greisinger GMH 3xxx series meter. The 100 mm probe tube reaches into ducts and tight spaces, while the 1 m cable keeps the display accessible.

Tips

For best accuracy, allow the probe to acclimatise to the measurement environment for a few minutes. Avoid condensation on the humidity sensor; if condensation occurs, dry the probe before use. The probe tip is not protected against dust or water jets, so keep it clean and dry.
