FROG-0 Factory boundary VOC monitor

The online VOC analyzer FROG-ZERO adopts the modular structure of MEMS micro preconcentration and desorption system+PID detector, which is small in size, high in accuracy, easy to install and maintain, and equipped with working software. The standard configuration can continuously measure the gas medium. The instrument can not only measure the VOC concentration at ppb level, but also measure the gas with high ppm concentration. The dilution device can also be selected. Widely used in: environment/plant boundary VOC detection gas purity analysis Indoor air quality monitoring process analysis Laboratory analysis Pollution field investigation

FROG-0 Factory boundary VOC monitor It is mainly composed of MEMS micro preconcentration unit, PID detector, injection device, main control unit, auxiliary device, etc. The sample is sucked into the instrument by the sampling pump, adsorbed by the preconcentration unit, periodically heated by the instrument to desorb the VOC gas in the preconcentration unit, and sent to the highly sensitive PID detector to detect the gas concentration. The configured working software can monitor the signal curve in real time. Because the gas has been preconcentrated, the detection sensitivity has been greatly improved to 0.05 ppb. The concentration calculation of the instrument is based on the signal difference, effectively eliminating the zero drift problem. The sampling and preconcentration process can be set by software, and the instrument is highly intelligent

Built in preconcentration and heating desorption unit, measurement sensitivity *, detection limit up to 0.05ppb Benzene has no zero drift, stable operation, controllable sampling process, high intelligence, strong anti-interference ability, and low humidity impact. The working software can view the spectrum in real time, store and calibrate the process simply, and is easy to use. The data can be output and transmitted remotely through the serial port
