Dual head dust sampler (constant current)

I. Overview

CCZ30D typeDual head dust sampler (constant current)It is a high traffic productConstant current dust samplerAdopting a separate design of sampler and air collector, it can adapt to more sampling modes; Sampling methods include fixed-point total dust and exhaled dust sampling, fixed-point organic pesticide aerosol sampling, and sixth level microbial sampling. 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 when sampling, easy to use.

CCZ30D typeDual head dust sampler (constant current)Meet the equipment requirements for occupational health technical service institutions in 2020.

2、 Technical parameters

3、 Solution

Total dust detection

It is possible to conduct fixed-point sampling of total dust concentration and metal dust concentration in the workplace, using a matching 40mm sampling clip and total dust sampling head connected to the equipment for sampling

Dust detection.

It is possible to conduct fixed-point sampling of dust concentration in the workplace and indoor inhalable dust, using a matching 20 L/min cyclone separation (in accordance with the BMRC curve) and a 40mm sampling clip connected to the equipment for sampling.

Microbial sampling (optional or separately only equipped with air microbial sampling)

Can be used for air microbial sampling, using a flow rate of 28.3L/min for sampling, and connected to a six stage microbiological apparatus using a matching bracket for sampling.
