The new Rapid RH 4.0 from Wagner Electronics combines their patented Smart Sensor and a redesigned Easy Reader with patent-pending Touch-n- Sense technology for easyto- use, fast and accurate RH testing. With Touch-n-Sense technology, the Easy Reader comes to life on contact with the Smart Sensor — turning on, taking a reading, and holding the data display for five minutes before powering off. Subsequent readings can be taken at any time with immediate results. ? www.wagnermeters.com
