RAE Systems Inc. offers the SentryRAE Steel, a 5-gas multi-sensor toxic gas monitor for extremely hazardous environments. The SentryRAE Steel is intended for use in industrial or emergency response environments where flammable vapors are present under normal operating conditions. The rechargeable lithium-ion or single-use alkaline batteries provide over 36 hours of operation, leaving plenty of margin for multiple work shifts to use the same instrument. It is designed to be used in industrial work environments that demand intrinsically safe (non-explosion-triggering) tools. It features a stainless-steel housing for easy cleaning and durability and a 20,000-point datalogging to support up to 64 hours of data using all five sensors at 1-minute intervals. All records can be downloaded to a standard PC for backup and storage. For more information, visit www.raesystems.com.
