Considering I would like to use this equipment on the production line to determine the correct moment to release parts from the gypsum mold, what is the minimum time between the measurements without a new calibration (same environment conditions)?

Asked by: Cesani
Hi Cesani, Thank you for the inquiry. The moisture measure is for inspection purposes. We do not offer NIST traceable calibration for the moisture measurement. For calibration cycle we suggest an annual basis, but this should be reviewed based on your application conditions. Best regards OMEGA

could this unit be used to check moisture content in flour

Asked by: Poppie
Hi Poppie This unit may not be sensitive enough for the light flour. We do not have test information on powder. Alternate to try is the HHGM68. Best regards OMEGA

will this device measure moisture in Styrofoam and Cardboard?

Asked by: mrksnw
Thank you for the inquiry. Readings are relative only. Manual gives expected range of readings for wood, gypsum, and cement. Some materials may not have enough water content to provide good response. Best regards OMEGA
