Midas EX
Explosion-Proof Extractive Single-Point Gas Detection for Reliability and Improved Safety
Midas
EX is an explosion resistant extractive single-point gas detector sampling system that can draw either a sample locally or from a remote point to a sensor cartridge inside the detector’s chassis.
A wide range of Asphyxiant, Toxic, Flammable, Pyrophoric, Corrosive and Oxidizer (including Oxygen) gas sensor cartridges are available to detect gases used or generated in Semiconductor Manufacturing and other industries.
Midas EX是一种耐爆炸提取单点气体探测器采样系统，可以在本地或从远程点抽取样本到探测器底盘内的传感器药筒。
各种窒息，有毒，易燃，易燃，腐蚀性和氧化剂(包括氧气)气体传感器盒可用于检测半导体制造和其他行业中使用或产生的气体。
