EA079 Ambient Air Noxious Harmful Gas Sampler

Brief introduction

Applicable to the collection of airborne particulate samples and NOX, SO2 and other harmful gases such as TSP/PM10/PM2.5

Features

1. A machine, with three channel simultaneous sampling function, can automatically and simultaneously achieve two harmful gases in the atmosphere constant current sampling and a particulate samples constant current sampling; machine integration structure design, compact structure, small volume, the transportation is convenient.

2 using ambient temperature, atmospheric pressure and 3 way high precision mass flow sensor and SCM Measurement and control technology, can automatically constant current sampling, sampling rate, volume and high precision. With quantitative, regular, interval sampling function.

3 sampling volume is the standard condition volume (the standard temperature is 273.15K and the pressure is the 101.325kPa state volume), does not need the manual computation, can display, store automatically.

4 overload automatic protection function

Sampling process, sampling flow for 5 minutes is not up to the set sampling flow rate of 90% or more than 10% of the set value, stop sampling.

5 power failure protection function

Sampling during power outages, can automatically store the sampling data, after the call to the sampling.

6 can store 162 sets of sample data.

7 big screen Chinese display, man-machine dialogue, simple operation, easy to use.
