As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The G-TECTA 4GP Gas Detector is designed to monitor the concentration of oxygen (deficiency), toxic or flammable gas, and provide visual, audible and physical (vibrator) warnings if preset limits are exceeded.The presence of any sensor is optional and the maximum possible is one flammable, one oxygen and two toxic.It comprises electronic circuits on printed circuit boards, a display, various LED indicators, a pump, a vibrator, a sounder and a rechargeable lithium-ion battery, all contained in a plastic enclosure providing a degree of protection of at least IP20.The flammable sensor used is either type VQ500 series by E2V Technologies, to Certificate IECEx SIR04.0014U, or 4P series by City Technology to Certificate IECEx SIR04.0013U, with a Code of Ex d IIC Gb and a maximum permitted ambient temperature of +55ºC. These sensors are certified to IEC60079-0:2007 and IEC60079-1: 2007.The IR Sensor used is type MSH-P Series by Dynament to Certificate IECEx SIR05.0053U, with a Code of Ex d IIC Gb and a maximum permitted ambient temperature of +60ºC. This sensor is certified to IEC60079-0:2004, IEC60079-1:2003 and IEC60079-26:2006.Marking of the Gas Detector is in accordance with IEC 60079-0:2007 and is:Ex ia d IIC T4 Gb (-20ºC ≤ Ta ≤ +55ºC).The apparatus is not designed for use in oxygen enriched atmospheres.Charging conditions:The battery must only be recharged in a non-hazardous area, using a Linde charger with an output (Um) of 9V.Non-rechargeable instrument:There is a non-rechargeable version of the instrument which has Temperature Class T3 and is therefore marked:Ex ia d IIC T3 Gb (-20ºC ≤ Ta ≤ +55ºC).The batteries must only be changed in a non-hazardous area.
