Beijing Zetron Technology Co., Ltd CN

Zetron MS104K-S1 Personal Gas detector 

MS104K-S1 is a maintenance-free portable single gas detector, it offers up to 2 years of protection-with no need for calibration, sensor replacement, battery replacement or battery charging. It\'s IECEx, ATEX, CNEX explosion proof certificated and meet the highest standards of quality and reliability to ensure workers\'safety and compliance.


Zetron MS104K-S1 Personal Gas detector 

The main detection principles of gas detection are: electrochemical, low-power infrared, etc. The detector is widely used in fire fighting, emergency rescue,restricted space,petroleum, chemical, metallurgy, refining,gas,warehousing, medicine and otheroccasions.

It offers a simple portable solution for the widest array of toxic gas and oxygen (O2) applications on the market. In addition to typical sensors such as carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen (NOx), ammonia (NH3) and sulfur dioxide (SO2), we offer less-common sensors including hydrogen chloride, hydrogen fluoride, phosphine, ozone, ethylene oxide, methyl mercaptan, arsine and phosgene.

The monitor has a large LCD providing maximum readability in the field and are made with six bright red LEDs allowing for a quick alarm notification. Constructed of strong and durable material, MS104K-S1 is designed to be comfortable yet drop-resistant.
