product details
The CD3 multi parameter gas detector adopts dot matrix display technology, fully Chinese interface operation, and can simultaneously detect oxygen, carbon monoxide, and nitrogen dioxide gases. The detection results are displayed on the screen at the same time, and users can start manual operation at any time. The standard USB interface can be used for charging, data transmission, and querying alarm results.
The CD3 multi parameter gas detector can be used for coal mining safety monitoring, concentration leakage in chemical workshops, gas leakage in pharmaceutical workshops, safety detection of operations in power and municipal pipelines, and hazardous gas safety detection in iron and steel smelting plants.
