1、 Adopting standards:
HJ/T375-2007 "Technical Requirements and Testing Methods for Environmental Air Samplers"
JJG956-2013 "Verification Regulations for Atmospheric Samplers"
2、 Overview:
The KC-6D intelligent atmospheric sampler is mainly suitable for sampling harmful gases such as SO2 and NOX in pollution sources. The sampler can simultaneously perform constant flow gas sampling of two gases, each equipped with a solution absorption bottle. The instrument is small, lightweight, convenient and practical, and can meet the sampling needs of departments such as environmental protection, health, labor, scientific research, safety supervision, military, and education.
3、 Technical features:
1. Dual channel constant current sampling, controlled separately by dual Japanese diaphragm pumps;
2. Overload automatic protection function;
3. Measure atmospheric pressure and automatically calculate standard volume;
4. Power down protection data, automatic recovery of sampling upon incoming call;
5. Large capacity storage of sampling data, up to 256 sets;
6. Real time clock function, convenient for users to query based on date and time;
7. The password protection function ensures secure operation.
