Eight physical quantities can be accurately measured with only one handheld unit, the OMNIPORT 20 from E+E Elektronik. The pluggable sensing probes allow easy configuration of the OMNIPORT handheld for various applications and measuring ranges. With its range of sensing probes, OMNIPORT 20 measures the following HVAC and process parameters : relative humidity (RH), temperature (T), dew point temperature (Td), absolute humidity (dv), mixing ratio (r), air velocity (v), water activity in oil (aw), water content in oil (x). The large display with back light and the robust housing allow the use of OMNIPORT in harsh industrial environments. E+E Elektronik.
