Gas Surveyor 400

The Gasurveyor 400 family of portable gas detectors represents a new generation of product from GMI. Developed from the widely used Gasurveyor and Gascoseeker® range, it offers the user accurate and reliable instrumentation using state of the art technology.

The Gasurveyor 400 offers the user a visual alarm, an 85 dBA audio alarm, data logging, a real time clock and automatic data transfer as standard. Alarm levels are present and when the alarms are 'on', a periodic 'confidence' signal is emitted.   Toughness is built into the Gasurveyor 400. The display is protected with toughened glass mounted on shock absorbing material, and the sensors are protected from dust and water by membrane and cotton filters. The instrument is designed to IP54 standard and the moulded, carbon filled polypropylene casing eliminates any static risk and maintains E.M.C. integrity.

Up to six gas ranges can be incorporated in one instrument with the L.C.D. display showing the gas levels in both analogue and digital forms. The internal microprocessor controls the display of operational and status information, with the whole display being back-lit in low light conditions.

Four push button switches access all the Gasurveyor 400 features making the instrument very easy to use. The GMI Instrument Management System (I.M.S.) allows the customer to manage and control the gas detectors ensuring that they are always working efficiently and to specification.   The instruments are designed to the latest European Standards and are certified for use in Hazardous Areas. Both rechargeable and dry cell battery options are available.   With its internal, automatic pump ensuring that the gas is drawn over the sensors, this breathing instrument weighs only 1.7kgs and measures 180 x 95 x 105mm.
