Urdukas Termohygrometer Vaisala HMP155

From 2004 to June 2013 the staion was equipped with the LSI-Lastem DMA570 termohygrometer.

Since 2013 the sensor was replaced with the new one: Vaisala HMP155 Humidity and Temperature Probe.

Feature/Benefits:

▪ Vaisala HUMICAP®180R sensor superior long-term stability

▪ Optional warmed humidity probe and chemical purge

▪ Plug-and-play

▪ USB connection for service use

▪ Fits with DTR13 and DTR503 radiation shields and also for a Stevenson screen

▪ Weather-proof housing IP66

▪ Optional, fast temperature probe

▪ Different output possibilities: voltage, RS-485, resistive Pt100

▪ Applications: meteorology, aviation and road weather, instrumentation

Technical characteristics:

Relative humidity

Measurement range 0 ... 100 %RH

Accuracy (incl. non-linearity, hysteresis and repeatability) at +15 ... +25 °C (+59 ... +77 °F) ±1 %RH (0 ... 90 %RH); ±1.7 %RH (90 ... 100 %RH); -20 ... +40 °C (-4 ... 104 °F) ±(1.0 + 0.008 x reading) %RH; -40 ... -20 °C (-40 ... -4 °F) ±(1.2 + 0.012 x reading) %RH; +40 ... +60 °C (+104 ... +140 °F) ±(1.2 + 0.012 x reading) %RH; -60 ... -40 °C (-76 ... -40 °F) ±(1.4 + 0.032 x reading) %RH

Factory calibration uncertainty (+20 °C /+68 °F); ±0.6 %RH (0 ... 40 %RH)*; ±1.0 %RH (40 ... 97 %RH)*

* Defined as ±2 standard deviation limits. Small variations possible, see also calibration certificate.
