The Rapid RH Total Reader combines the Easy and Smart Reader into one convenient device.  It quickly reads concrete and ambient conditions and automatically sends the data via Bluetooth® to the DataMaster™ L6 app.  It also features an LCD display.

I still have the 4.0 EX Sensors. What should I do?

You’re still working with the best concrete RH test in the industry.  Use the rest of your 4.0 EX Smart Sensors and when you’re ready to replenish your sensor stock, simply order a new value pack of L6 Sensors.

You’ll need to purchase a Rapid RH Total Reader, and you’ll need the NEW Rapid RH L6 Insertion Tool.  Once you have those, you’re ready to make a seamless transition to the next generation of RH testing technology.
