Dual O2/CO2 Monitor, 0-25% and 0-10,000ppm
Description
Dual O2/CO2 Monitor, 0-25% and 0-10,000ppm
PureAire Monitoring Systems’ Dual O2/CO2 Monitor is designed for continuous monitoring of oxygen and carbon dioxide in confined spaces. The monitor is ideal for facilities that use inert gases, including, but not limited to, nitrogen, helium, carbon dioxide, and argon.
The Dual O2/CO2 Monitor is suitable for environments such as cryogenic facilities, breweries, food processing plants, pharmaceutical manufacturing, laboratories, hospitals, and universities. The monitor will remain accurate at temperatures as low as -40c. PureAire’s durable, non-depleting, zirconium oxide sensor cell and non-dispersive, infrared sensor (NDIR) cell, will last 10+ years in a normal environment, without needing to be replaced.
