1、 Product Description:

TQC-1500Z is a conventional instrument widely used for collecting air toxic substance samples in environmental hygiene, labor hygiene, indoor environment, etc.useMicrocomputer constant current system controlLCD digital display system, menu settings, AC/DC dual-use.

This instrument uses a microcontroller for circuit timing and power control. Its compact structure, stable performance, small size, light weight, easy portability, and wide sampling range can be matched with various absorption tubes, as well as various solid adsorption tubes. It is currently an ideal and practical air sampler among small portable air samplers in China.
