Air check Advantage Ex Benzene Monitor


Item #: 99008

Product Summary

The Air check Advantage Ex Benzene Monitor is a compact, extractive continuous gas monitoring system designed to monitor in hazardous areas. The system uses our proprietary disposable electrochemical sensor cell combined with a long life pyrolizer to provide extremely sensitive Benzene monitoring. Unlike traditional LEL solid-state detectors, the Air check Ex pyrolizer technology is extremely sensitive and capable of detecting TLV parts-per-million concentrations of Benzene without being affected by humidity or other environmental conditions.

The heart of the monitoring system is a long life pyrolizer designed to convert Benzene to an electrochemically active gas detected on PureAire’s sensor cell. The Air check Ex electronics, pyrolizer, sample pump and sensor cell are housed in a weather and explosion-proof enclosure suitable for installation in Class 1, Division 1, Group B, C, and D hazardous areas.

The instrument’s “smart” circuitry continuously monitors sensor cell status and sampling system performance. Continuous sensor cell operation is transmitted via 4-20 mA signal to PureAire controllers, PLC’s or remote alarm systems. Should a system error occur, the Air check Ex outputs a 2 mA signal to remote alarm/control systems to immediately alert control room personnel.

Low Annual Operation Cost
The PureAire Air check Ex has a low annual maintenance cost. Combined with our built-in, long life pyrolizer and sample pump, the Air check Ex will lower your annual operation costs. When compared to competitive gas monitors, it will pay for itself in just a few years.

Connects to DCS and PLC Controls
The Air check Ex Benzene Monitor is 24 V DC powered and transmits continuous gas concentration levels to any distributive control system, programmable logic controller or PureAire’s proprietary single and multichannel controllers. The Air check Ex Monitor can be operated remote up to 1,000 meters, 0.6 miles from centralized distributive control systems.
