PhoCheck+ has a highly sensitive patented photo-ionization detector (PID) at the heart of it. With a dynamic detection range capable of 1 ppb up to 10,000 ppm, PhoCheck+ is the only PID on the market able to detect Volatile Organic Compounds (VOC's) at their very low ppb toxic thresholds and lower explosive limits. PhoCheck+ has redesigned handheld VOC and toxic gas detection to meet the industry needs of today and tomorrow. With new improved features PhoCheck+ is now a fully upgradeable instrument enabling you to upgrade from the basic PhoCheck+ 1000Ex version all the way up to our revolutionary FirstCheck 6000Ex multigas instrument.
