1BT-3 Constant Current Individual Dust SamplerOverview

The BT-3 constant current individual dust sampler is suitable for sampling fixed-point individual toxins and dust substances such as metals in the workplace; It is also applicable for routine and emergency monitoring of the environment, atmosphere, and public health.

The constant flow air sampler mainly consists of an operating system, an intelligent control system, an air pump, and a flow measurement system. Can work continuously for more than 20 hours, fully charged at once, easy to sample. This instrument has the advantages of real-time flow rate, sampling volume, sampling time, temperature, air pressure, and electricity display, compact structure, small size, light weight, durability, strong load capacity, stable and accurate flow rate, and low noise. It can be carried with you during sampling, making it easy to use.
