New Concept! Radon Detector!!


The RS9A is the new innovative radon sensor, which has the high sensitivity, 0.3cpm/pCi/l. This sensor is designed for the IAQ monitor, air purifier and auto ventilation system. A breakthrough in FTLAB’s patent technology which received a New Excellent Technology certification in 2015, the RS9A 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 RS9A both are ±15% at 10pCi/l radon chamber test.
