Key Benefits
Long-term stability and easy maintenance
The probe can be calibrated using a PC with a USB cable, with push buttons, or with the MI70 indicator.
Durability
Protected from default with a sintered Teflon filter, the HMP155 has the maximum build-in protection against liquid water, dust, and dirt.
Warmed probe
The sensor head is warmed continuously to keep the humidity level inside it below the ambient level, which reduces the risk of condensation forming on the probe.
