Reliable readings

The Fluke 971 is a reliable Temp/humidity meter. It is rugged and holds up to the demanding conditions it is used in. It is easy to use with a fairly large readout screen.

HVAC supervisor/lead

This unit was out of calibration within the first 6 months of use. Meter was kept in office and specifically purchased for checking calibration of field devices. Rapidly this meter was over 7% off calibration. Checking with fluke, cost of re-calibration was near cost of new meter. Looking into buying a different RH meter. Will not be a fluke.
