Instructions

HD32.3 - 43 - V1.4
Combined probe of relative humidity (RH) and temperature HD3217.2, HP3217R
- Don’t use your hands for touching the sensors with your hands, avoid dirtying them with oils,
greases or resins.
- The sensor support is in aluminium so they can break easily with shocks, blows, falls.
- The sensors can be cleaned by the dust, the pollution with distilled water and a brush very soft
(i.e. by yew).
- If the measurements are not adequate, check that the sensors are not dirty, corroded, chipped or
broken.
- To check the appropriateness of the RH measurement you can use the standard satured salt so-
lutions: HD75 (75% RH) and HD33 (33% RH).
(*) The probe is calibrated, the calibration data are kept into the SICRAM module memory.

response time is the time spent to reach the 95% of the final value. The measurement of the response time is
done with a negligible air speed (motionless air).
HP3217, HP3217R
