1、 Product Introduction

TWA-300NThe dual channel low flow air sampler is a conventional instrument for parallel sampling of harmful gases. This machine is controlled by a microcomputer constant current systemLCDThe digital display system can be used for both AC and DC, powered by lithium batteries.

This instrument uses dual pumps to independently complete two sets of gas paths without interference. The circuit is controlled by a microcontroller chip technology and is equipped with a high-energy lithium rechargeable battery. It has a long continuous operation time, easy operation, high timing accuracy, durability, and compatibility with AC and DC, making timing convenient and fast. countdown1－99hour59Choose freely based on the scope. It is currently the most ideal and practical dual gas path gas poison sampler among similar instruments in China.
