It doesn’t get easier than the Rapid RH^® 4.0.

Your time is valuable. Staring down at an owner’s manual or fussing with a handheld meter and cabling adds unnecessary complexity and does not get the job done quickly. 

The Rapid RH^® 4.0 method is simple and quick. The easy installation guide, unmatched speed of equilibration, speed of readings and sensor design (nothing sticks above the slab to get damaged or stolen) mean headache-free monitoring of the relative humidity in the slab.

To obtain readings, just insert the compact Rapid RH^® 4.0 Easy Reader into an installed Smart Sensor and get a reading that anyone (owner, architect, general contractor or floor installer) on the jobsite can take. The Rapid RH^® 4.0 Easy Reader now features the patent-pending Touch-N-Sense^® Technology. On contact with any 4.0 Smart Sensor, the Easy Reader turns on, takes a reading, then holds the readings for up to 5 minutes after it has been removed from the Smart Sensor before powering down - all automatically!
