% RH, a temperature difference of 1°C (1.8 °F) typically results in an error of 3 %RH on relative humidity. When using Hygropin, it is good practice to monitor the display for temperature stability. The probe should be given sufficient time to come to equilibrium with the environment to be measured. The larger the initial temperature difference between the probe and the environment, the more time is required for temperature equilibrium.
ENTER Confirm a selection and data capture. 3.4 Standard Display Depending on the settings the Hygropin is able to display: • relative humidity and temperature measured by two probes • calculate psychrometric parameters like dew / frost point etc. for both probes •...

When recording data from two probes at the same time, the recording capacity per probe is cut in half. The Hygropin features two data logging mode: start-stop (recording ends when the memory is full) and loop (when the memory is full, the oldest record is dumped to make room for a new record) Data logging can be started and stopped from the keypad.
ASTM F 2170-09 Special note NIST traceability: All probes for the Hygropin are factory calibrated referring to the Swiss Calibration Service (SCS). An individual calibration certificate is included with each probe. SCS is accredited with the Swiss Federal Office of Metrology which is a signatory of the BIPM (http://www.bipm.org/) Under the Mutual Recognition Agreement NIST recognizes all registered in the BIPM database.
