The Sperian Biosystems MultiPro is the smallest and easiest to use confined space gas detector offered by Sperian Instrumentation. Extremely affordable, it is packed with features. It offers real time readings of up to 4 gases simultaneously, one-button operation including calibration, an easy to read LCD display, audible, visible and vibrating alarms, standard event logger and black box data logger, an IrDA port for easy communication with a PC, and an optional sample draw pump — all in a rugged, compact and affordable instrument.

The Sperian Biosystems MultiPro does it all, and it can be configured for your exact needs. Three sensors and up to 4 channels of detection let you monitor for any combination of O2, LEL, CO and H2S. Compatibility with the Biosystems MultiPro IQ Express Dock allows users to automate recordkeeping while significantly reducing labor and calibration gas expenses.

The Sperian Biosystems MultiPro is constructed of an engineered polycarbonate frame with a rubber overmold, making it both tough and easy to handle. Power comes from interchangeable alkaline (3AA) or rechargeable battery pack. The optional sample draw pump is controlled by the instrument and automatically tests for proper seal whenever the pump is turned on. The instrument also automatically notifies the user if a blockage is detected at the pump.
