Instrument Introduction

New Universe Four in One Gas Detector

XP-302M (automatic suction type) can simultaneously detect the concentration of four gases: flammable gas, oxygen, hydrogen sulfide, and carbon monoxide. The sensor component is easy to install, reduces maintenance burden, can be connected to external alarms, can record data, has explosion-proof design, can be used in various hazardous areas, has a large display dial, accurate and reliable readings, is lightweight and small in size, and can choose 3 or 4 gas models.
