The Gasurveyor 500 is a highly flexible, portable gas detector which can be configured from a simple single gas instrument, through to a sophisticated four gas multi-tasking instrument. The instrument is designed to the latest standards and is certified for use in Hazardous Areas.
The Gasurveyor 500 can contain up to six gas ranges with the following ranges being possible:
LEL, 0 to 100%,
Volume gas, 0 to 100%
PPM Flammable
Oxygen, 0 to 25%
Toxic range 1
Toxic range 2
Ranges of Operation
LEL, 0 to 100%
The LEL range indicates the explosibility of the flammable gas in the sample. This is displayed as a percentage of the lower explosive limit (LEL) of the gas.
Any combination of flammable gas from parts per million (ppm) through Lower Explosive Limit (LEL) to percent volume, oxygen, carbon monoxide and hydrogen sulphide can be selected to ensure that your exact requirements are met. All of the Gasurveyor 500 Series are dual mode instruments, making them suitable for both surveying work and confined space.
Toxic Ranges
Two toxic ranges are possible on the Gasurveyor 500 series of instruments. The toxic ranges measure on the ppm scale. The toxic sensors are subject to the effect of pressure transients and should be operated at normal atmospheric pressure conditions. The sensors have a normal operating life of two years.
Datalogging
The Gasurveyor 500 series memory can store up to 1000 logged entries which are dependent on number of Gas ranges and duration of each ON/OFF session. The memory will overwrite entries in the event of an overflow.
Operating Modes
The Gasurveyor 500 is a dual configuration instrument. It operates as a Confined Space Monitor (CSM) or as a Combustible Gas Indicator (CGI) depending on the button used to switch it on.
Confined Space Monitor (CSM)
Operation
In this mode the instrument operates as a safety monitor for use when entering confined spaces which may contain hazardous gas mixtures (flammable, toxic and/or asphyxiant). The instrument samples the ambient atmosphere to which the operator is exposed and generates alarms for low oxygen, high oxygen, high flammable gas, high toxic gas, Short Term TWA (STEL) and Long Term TWA (LTEL).
Combustible Gas Indicator (CGI)
Operation
In this mode the instrument operates as a gas indicator drawing a sample via a probe from points where gas is suspected to be present. Alarms, by default, are disabled in CGI mode, as the instrument is generally used for measuring gas levels rather than monitoring for the presence of gas.
Dual mode operation - Combustible Gas Indicator (CGI) / Confined Space Monitor (CSM).
Rechargeable or alkaline battery options.
Approved to European and North American safety standards.
Extremely robust anti-static case.
Simple to use.
Built-in sampling pump as standard.
Large LCD with automatic backlighting in low level light conditions.
Compatible with the GMI range of Auto Calibration Systems.
Audible / visual alarms for all gas ranges.
Fault alarms for low flow, low battery etc.
Probes for a wide range of applications.
