Touch-n-Sense is our patent-pending technology, integrated into the Rapid RH® Easy Reader and Bluetooth® Smart Reader to enable it to automatically take a reading when placed in contact with the Rapid RH 4.0 EX or 5.0 Smart Sensors. Once the bottom of the Reader makes contact with the Smart Sensor, the Reader comes to life and takes a reading. The Easy Reader and holds the reading for 5 minutes, even when removed from the test hole, before turning itself off. The Smart Reader, on the other hand, will send its readings to your mobile device via Bluetooth®. It’s just that easy.
