External probe for hard-to-reach areas
The separate sensor on a coiled cable enables precise measurements in HVAC systems, corners and enclosed spaces without inserting the entire instrument.
Fast and reliable response
Sampling every 1 second and a sensitive sensor ensure immediate and stable data for monitoring temperature and relative humidity.
Clear backlit display
LCD 32 × 35 mm with MAX/MIN, Data Hold and overload indication provides a clear view even in dark environments.
