Rapid RH Common Questions – Part 1 of 4

Product Update: The Rapid RH^® 4.0 shown in this video has been replaced by the Rapid RH L6.

Questions answered in this video:

Can Smart Sensors be reused or recovered?
Does the Rapid RH reader ever need calibration?
What type of documentation do you recommend?

Part 1: Sensor reuse, reader calibration, and documentation (this video)
Part 2: Slow-drying slabs, HVAC conditions, and drying faster
Part 3: High RH under an old floor, RH vs. MVER, and rechecking after installation
