The micro processor control and multi-point calibration gives
the PCMini52 RH probe excellent performance in terms of
accuracy and linearity. The mini probe can provide two linear
analog outputs for temperature and relative humidity, dew
point, absolute humidity or wet bulb temperature.
Highlights
• Output can be % RH, calculated absolute humidity, dew
point or wet bulb temperature + temperature
• Excellent linearity, (P) micro processor temperature
compensated
• Low power consumption, fast settling time
• Small size: L = 80mm, ø12mm (L = 3.15”, ø0.47”)
