BT-5000 Constant Current Air Sampler

BT-5000 Constant Current Air Sampler

I. Overview

BT-5000A constant current air sampler is an instrument used to collect gaseous or vapor samples from the atmosphere, suitable for sampling individual toxic substances and dust substances such as metals at designated locations for occupational hazards in the workplace; It is also applicable to the environment and atmosphere,public healthRoutine monitoring and emergency monitoring.

The constant flow air sampler mainly consists of an operating system, an intelligent control system, an air pump, and a flow measurement system. Fully charged once for continuous operation20More than one hour, convenient for sampling work. This instrument has real-time flow rate, sampling volume, sampling time, temperature, atmospheric pressure, and electricity display. It has the advantages of compact structure, small volume, light weight, durability, strong load capacity, stable and accurate flow rate, and low noise.Can be carried with you for easy use when sampling.

2、 Application Fields

BT-5000The constant flow air sampler is a disease prevention center,environmental monitoringThe ideal instrument for short-term or long-term air detection and sampling by environmental protection personnel in colleges, universities, research institutions, and testing institutions.
