Radiodetection GMI Gasurveyor ppm500 | High-Sensitivity Gas Leak Detection | Refurbished

The GMI Gasurveyor ppm500 is a precision gas detection instrument engineered for high-sensitivity leak detection and comprehensive bar hole surveys. It builds upon the performance of the Gascoseeker 2-500, offering measurement of % LEL and % volume flammable hydrocarbons with the essential addition of ppm ranges for exacting gas escape identification.

What are the gas detection capabilities of the GMI ppm500?

The ppm500 provides high-sensitivity measurements across multiple ranges, including 0 – 1000ppm, 0 – 100% LEL, and 0 – 100% Volume. It features a resolution equivalent to 5 ppm methane and a fast-response search mode paired with an audio/visual Geiger function for rapid leak source detection.

Is this gas surveyor suitable for hazardous industrial environments?

Yes, this unit is built within a rugged carbon-loaded polypropylene case sealed to an IP54 rating, ensuring durability for outdoor use. It holds comprehensive safety certifications including ATEX (Ex II 2G Eex ia d IIC T4) and UL913 (Class 1 Div 1 Groups ABCD), operating reliably between -20oC and +50oC.

How does the integral sampling system ensure accurate readings?

The device utilizes an integral pump equipped with a flow fail sensor to maintain consistent sampling during operation. The sample path is further protected by a hydrophobic filter and an auto pump switch off feature to prevent damage from water ingress.
