Confined Space Entry Monitor (4 Gas)
The QRAE is a 4 gas confined space entry monitor that measures LEL, O2, CO, and H2S concetration levels. All models feature an integrated pump and rechargeable lithium ion battery.
The QRAE is a well known, economical, and dependable dedicated confined space entry monitor. The QRAE simultaneously measures LEL, O2, CO, and H2S providing instantaneous readings for percent LEL, percent volume (O2), and ppm readings (H2S, CO). it can operate for up to 12 hours from its rechargeable Ni-MH battery and includes an alkaline adapter for extended runtimes. The QRAE can be operated with one hand, features auto zero capability, and is excellent for use in any confined space application like landfill operations, cruise ships, wastewater treatment plants, coal mines, etc...
A loud 90 dB audible buzzer and flashing LEDs indicate alarms to the user. The QRAE has both high and low user adjustable alarm limits for all gases. STEL and TWA alarm limits are provided for toxic gases. Every QRAE includes built in datalogging for up to 20,000 points of data and can be downloaded to a PC along with the serial number of the unit, date/time, user id, site number, and calibration date. Field calibration is easily performed for zero and span gas, and the QRAE is compatible with the AutoRAE automatic calibration station.
The QRAE is IP55 rated and resitant to dust, water, and EMI. Designed for use in harsh environments, the casing is metal and ABS plastic protected by a strong rubber boot. The QRAE is rated intrinsically safe and comes with a lifetime warranty on non consumable components.
