New Concept! Radon Detector!!

The RD200M is the new innovative fastest radon sensor, which has the highest sensitivity, 30 cph/pCi/l on the market today. This sensor is optimized for the IAQ monitor, Air purifier, Radon detector and Auto ventilation system. A breakthrough in FTLAB’s patent technology which received a New Excellent Technology certification in 2015, the RD200M uses a dual probe structured pulsed ionization chamber and a special high impedance differential amplifier circuit to offer the highest signal to noise ratio. It effectively detects the secondary charges which were generated from collisions with air and α-particle caused by Radon or Radon's progeny. The accuracy and precision of the RD200M both are ±10% at 10pCi/l, which has been tested by the international standard Radon Testing Laboratory in KTL. Each sensor has been individually calibrated by equipments which are already calibrated to traceable international standards.
