Product Features

Constant voltage and constant current: closed-loop control, flow rate is not affected by voltage fluctuations and air resistance changes.

Ultra long battery life: The instrument can work continuously for 30 hours under a load of 5kPa at 100mL/min.

Traffic self calibration: With open calibration permissions, users can control the accuracy of each sampled traffic and can have automatic calibration.

Intelligent sampling: The instrument intelligently monitors time, progress, and battery level, and can shut down at scheduled times.

Patent filtration: The filter can effectively protect the pump from damage caused by particulate matter, and can also be used for pre filtration of hydrogen chloride and other samples.

Tri fixed sampling: timing, constant volume, and constant time interval form the tri fixed sampling mode, making PC-TWA easier.

Highlight advantages

Constant volume sampling: Built in high-speed integration algorithm to ensure accurate constant volume; Unique constant volume sampling, perfectly solving the problem of simple gas and non reactive gas sampling.

Support self calibration: Built in precision electronic flowmeter, users can calibrate flow under different loads. Ensure that the sampling flow is authentic and the data is reliable each time.

Lightweight and portable: The mold can be molded in one go, with a single machine weight of less than 400g. Combined with a kit, it is both lightweight and does not affect workers' operations during individual sampling.

One click screen lock: After the instrument is running, it can be locked with one click. When individuals sample for a long time, it can effectively avoid misoperation caused by workers' work.
