The STF200E-PID series utilizes photoionization detection, enabling rapid and accurate detection of thousands of volatile organic compounds (VOCs). It utilizes a patented vacuum ceramic tube ionization PID lamp (10.6 eV) with a lifespan of over 20,000 hours and an expected service life of more than five years. It features a built-in long-life vacuum diaphragm air pump for sensitive detection and rapid response, with a typical T90 response time of less than 20 seconds.
