oxygen alarm for cold rooms

ESRAD-02-ZR oxygen deficiency safety alarm



overview

  • A low cost, low maintenance oxygen alarms for low temperatures
  • Ideal for cold rooms including freezers as low as -50°C
  • Calibrated, easy to install and ready to measure

ESRAD-02-ZR Oxygen Deficiency Alarm for Low Temperature, protects staff in enclosed areas near storage cylinders of nitrogen, argon, ammonia, chlorine, propane, nitrous oxide, helium, argon, or other inert gases.

Per both the Occupational Safety and Health Administration (OSHA) and National Institutes of Health (NIH) hazardous conditions may include areas where the oxygen concentrations fall below 19.5% or above 23.5% and require oxygen deficiency monitors.

Our Oxygen Deficiency Alarm for Low Temperatures is commonly used in hospitals, laboratories, pharmaceuticals, cryogenics, process cooling, freezers, manufacturing, food + beverage, and research facilities.

The oxygen deficiency safety monitor will stay accurate at temperatures as low as -50°C, without needing maintenance and does not require zero calibration.
