RAE Systems

QRAE II Gas Detectors

The QRAE II by RAE Systems is a compact personal gas detector. The QRAE II is a durable and versatile diffusion or pumped one-to-four gas monitor for detection of combustibles, oxygen, hydrogen sulfide, or carbon monoxide. The QRAE II is loaded with features making it the perfect instrument for confined space entry. Standard features include easy-to-change battery packs, easy access to sensors, internal vibrating alarm, loud 95dB audible alarm, and a water-resistant IP-65 case design. The rechargeable Lithium-ion battery delivers up to 14 hours of continuous operation in diffusion mode (a spare alkaline battery adapter is included for 10 hour back-up operation).

Industrial Safety offers both the Diffusion Model and the Pump Model with the powered internal sample draw pump. The RAE Systems QRAE II is one of our most popular and best selling confined space 4-gas monitors. The Pump Model is our most popular version on the QRAE II as it is capable of pulling a sample from a remote location such as a sewer without having to physically enter the potentially hazardous area. Once the worker can determine that the area is clear of a hazard, they can enter with either a pump or a diffusion model to continuously sample the work area. The Diffusion Models Battery Packs will typically last longer as well.

The AutoRAE Lite Docking Station for QRAE II enables fast and easy bump testing and calibration of the monitor, streamlines the data download process, and saves calibration gas to deliver the lowest cost of ownership on the market.

The QRAE II from RAE Systems is a great value and is one of the easiest and most functional Gas Detectors in the industry. The QRAE II works well in many applications including refinery work, oil rigs, fire fighting, confined space entry, maritime industrial work, utility companies, gas plants, military, environmental and safety engineers, hazmat first responders, and industrial safety engineers.
