Special Safety Features

Rechargeable battery backup with low power alarm, tamper-resistant alarm setpoints to prevent user override, calibrations error detection, and front panel lock-out.

Special Safety Features

The MODEL 221R is certified by a 3rd party testing lab to meets UL 61010-1 Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use.

path

Washdown-Ready Metal Enclosure

The powder-coated aluminum enclosure of the Analyzer is designed to provide protection against ingress of dust and water from low pressure spray. Design protects analyzers in difficult industrial environments and allows for low pressure washdown of the unit.

path

Audible Alarms & Relays

Detection of an Oxygen-Deficient environment will trigger a 95 dB alarm to warn of danger. Additionally, includes relays for triggering safety beacons or exhaust fans.

Audible Alarms & Relays

Alarms are preset to oxygen levels mandated by OSHA. Normal ambient atmosphere has an oxygen concentration of 20.9%. The OSHA Respiratory Protection Standard 29 CFR 1910.134 states 19.5 percent oxygen as the level below which an oxygen-deficient atmosphere exists and requires, generally, that all oxygen-deficient atmospheres be considered immediately dangerous to life or health.

10-Year Sensor Life

The Zirconium Oxide Sensor provides up to 10-years of operational life while only requiring simple, periodic calibration. Detection technology is IDEAL for monitoring oxygen safety levels. Maintains accuracy over wide temperature range and not affected by changes in barometric pressure.

path

10-Year Sensor Life

AMI's zirconium oxide sensors provide the best option for monitoring oxygen levels in inert atmospheres due to their stability, limited maintenance and up to 10 years of service life. Electrochemical O2 sensors require regular calibration and replacement, making them less suitable for oxygen deficiency monitoring.

path

Optional Remote Probe

Allows monitoring of locations away from the control unit. Comes standard with a 12 ft (3.6m) cable but can be extended by the customer up to 300 ft (91.4m).
