RKI Instruments, Inc. Single Point Stand Alone Monitor PS 2

The PS 2 Model from RKI Instruments, Inc. is a single point stand-alone gas monitor designed for the detection of lower explosive limits (LEL) of various gases and vapors. It features a Metal Oxide Semiconductor (MOS) sensor known for its long life and low maintenance requirements. The device includes two alarm levels, each activating a 12 amp relay, and provides both audible (85 dB) and visual alarms through LED indicators. This monitor operates on standard input voltages of 24 VDC, with optional 115 VAC or 48 VDC configurations. It is housed in a durable ABS plastic enclosure suitable for indoor use and is designed for easy installation with accessible wiring hubs. The PS 2 is equipped with a 30-foot sensor cable, which can be adjusted for different lengths as needed. The PS 2 is applicable in various industries, including battery storage, petrochemical plants, refineries, and manufacturing facilities. It is particularly effective for monitoring hydrogen in battery rooms and detecting flammable gases in general industrial settings. The operating temperature range is 35¬8F to 120¬8F (2¬8C to 49¬8C), and it can function in relative humidity levels of 10% to 95% RH, non-condensing.
