The ST150 / ST350EX PID is a fixed PID gas detector suitable for the detection of volatile organic components (VOC’s). The ST150 / ST350 EX PID utilise the Photo Ionization measuring principle and is equipped with a 10.6eV PID lamp with a patented fence electrode. Because of this “fence”, the sensor has a better protection against atmospheric humidity and pollution.
