TYH-30 respiratory dust sampler

1、 Product Introduction

TYH-30 Intelligent Breathing SystemDust samplerIt consists of a high-performance suction pump, microcomputer time control, battery voltage display, flow regulation, automatic feedback constant current, and is also equipped with various dust pre collectors. The total dust pre collector is used to measure the total dust concentration; Another type of impact pre collector is used to determine the concentration of respiratory dust. This pre collector can separate respiratory dust and non respiratory dust that are harmful to the human body, and can collect both respiratory and non respiratory dust samples at once. Its separation efficiency meets the "BMRC" curve standard, making it a reliable and practical dust pre separation device. The instrument is controlled by a microcomputer constant current system, an LCD digital display system, menu settings, and can be used for both AC and DC. It has the advantages of small size, light weight, easy portability, high timing accuracy, accurate measurement, stable flow rate, and easy operation.
