Introduction

This type of evaluation based on the outline JJF 1016 "Measuring Instruments type evaluation outline guidelines for the preparation", JJF 1015 "count Evaluation of the amount of equipment type and type approval of universal norms "and JJF 1001" common measurement terms and definitions of "compilation. The outline of the type evaluation technical indicators reference to GB/T 17061-1997 "workplace air sampling equipment Technical Specifications ", HJ/T 375-2007" ambient air sampler technical requirements and test methods ", HJ/T 376- 2007 "24 thermostatic automatic continuous ambient air sampler technical requirements and test methods", JJG956-2013 "big Air sampler ", GB/T 11606-2007" analytical instruments environmental test method "and other technical regulations. This type of evaluation outline for the first release. Air sampler type evaluation outline

3 Overview

Sampling is an acquisition instrument atmospheric gaseous or vapor samples, which works with a sample pump, through The steady flow through different measures and timing synchronization method, achieve the quantitative collection. According to the instrument to withstand the load capacity, the instrument Divided into Class A (bearer 0.5kPa) and Class B (bearer 4.5kPa). The sampler consists of three parts collector flow system and pump power systems. Collectors into the absorption tube, filter Sampling clip, solid particle sampling tube for collecting a small amount of gaseous pollutants mining trachea, syringes, vacuum bottles. Flow measurement systems typically employ a gas flow rotameter, flow regulating assembly also means, and a timing control means Temperature control devices. Suction power system is actually a vacuum pumping system, usually by an electric vacuum pump, scraper Pump, membrane pump, electromagnetic pump or other suction pump and other components.
