SY-QB601PID is a pump suction handheld volatile organic compound (VOC) gas detector that uses an imported third-generation photoionization detector (PID) to improve detection accuracy and response time. It has a short response time, wide detection range, high resolution, and small detection error. It can detect VOC gases in real time from 0.1 to 15000ppm. It can be connected to an external sampling pipeline of up to 30m, and the detection data is equally accurate. It is equipped with a built-in temperature, humidity, and pressure sensor, which automatically compensates to ensure detection accuracy. It also has a large capacity lithium battery pack and a long standby time. Built in high-performance long-life diaphragm air pump, fast response, fast recovery time - automatically stores detection data and can be downloaded to PC mg/m ³ and ppm concentration units for interchangeable replaceable filtering devices, easy maintenance - can query alarm records, real-time display STEL, TWA and other data - intrinsically safe explosion-proof certification.
