The GMI Shipsurveyor by Teledyne is for marine applications with a choice of 8 models. Equipped with an internal pump capable of drawing a sample from 30 metres, making it ideal for confined space monitoring, inerting, pre-entry checking, tank cleaning and a host of other applications in vessels such as LNG / LPG Tankers, Oil Tankers, Fruit Carriers and Refrigerated Cargos.

Up to five gases can be measured simultaneously. Flammable gas is measured by an infrared sensor, which has a long life and is resistant to poisoning. The default calibration is Butane; other calibrations are available: Methane, Propane or Pentane. Carbon Dioxide is also measured with an IR sensor.

On startup, the pump is automatically on for confined space monitoring. Switch the pump off, and the instrument acts as a Combustible Gas Indicator (CGI) for ambient monitoring.

The software enables the downloading of readings vessel location data and the printing of calibration certificates.
