• Includes: 5 x L6 Smart Sensors, 10 extensions, 5 protective Caps with Rubber Plugs and Butyl Gasket, 5 stainless Steel Covers, certificate of Calibration, Floor Map and an Instruction Manual
• Rapid RH L6 sensors feature a customized version of the SHT35 humidity sensor from Sensirion that has a +/-2% accuracy tolerance at 50% and 90% relative humidity (RH)
• This important aspect of the L6 concrete RH testing system puts it in direct compliance with ASTM F2170
• Standard SHT35 humidity sensors, found in other concrete RH test systems, start to deviate from the +/-2% tolerance at RH levels as low as 50%
