QCD-3000PAdvantages of Programmable Atmospheric Sampler:

1.This instrument is widely used as a new type of instrument for collecting toxic substance samples in environmental health monitoring, occupational health monitoring, indoor environment, scientific research, and other fields.

2.This instrument adopts microcomputer chip control technology, built-in imported vacuum pump, high-performance nickel hydrogen rechargeable battery, and can run continuously after one charge12More than hours

3.Easy to operate, high timing accuracy, sturdy and durable, compatible with AC and DC, convenient and fast timing selection, timing range1Minutes~99hour59It can be set arbitrarily and sampled at intervals programmed according to working hours（approach8Hourly time weighted sampling）.3.Automatically turn off the power during shutdown. It is currently an ideal sampler among similar instruments in China.
