MGT is a Portable Multi-Gas Detector engineered for personal protection and use in confined spaces detecting Oxygen (O₂), Hydrogen Sulphide (H₂S), Carbon Monoxide (CO) and Combustible Gases

IECEx Approved

Protecting workers against Oxygen deficiency, Toxic gas poisoning and Combustible gas explosion by continuously measuring Oxygen (O₂), Hydrogen Sulphide (H₂S), Carbon Monoxide (CO) and Combustible Gas levels. These gases that cause the majority of industrial accidents. The MGT raises the alarm through visual, vibrating and audible means when at dangerous levels displaying at the moment concentrations.. The unit has in built data logging which can be downloaded to a PC using the MGT IR Link for analysis and is provided with battery charger.

  • IEC Ex approved
  • Detects Oxygen, Hydrogen Sulphide, Combustible Gases (Calibrated for Methane(CH₄)) and Carbon Monoxide.
  • Easy to read and view display
  • Easy to calibrate and check
  • Small and Easy to carry
  • Robust and waterproof case
  • Clearable Max and Min gas concentration recorded
  • Displays Time Weighted Average and Short-term Exposure Limit
  • Adjustable alarm levels using the SGT IR Link
  • Data logging for the last 30 events
  • Flashing and sounding and Vibrating Alarm

Poisoning: Senko sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.

Hazardous Areas (IEC Ex Certified)

IEC Ex approved gas detectors and sensors for use in Zone 1 and Zone 2 areas within Australia for both Toxic and Flammable gases.

Hazardous Areas are areas in which an explosive gas atmosphere is or may be expected to be present, in quantities such as to require special precautions for the construction installation and use of equipment construction, installation and use of equipment. Hazardous areas are classified into 3 zones based upon the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:

  • Zone 0 - Area in which an explosive gas atmosphere is present continuously or for long periods or frequently.
  • Zone 1 - Area in which an explosive gas atmosphere is in which an explosive gas atmosphere is likely to occur in normal likely to occur in normal operation occasionally.
  • Zone 2 - Area in which an explosive gas atmosphere is not likely to occur in normal operation but, if it does occur, will persist will persist for a short period for a short period only.
  • Non hazardous area (safe area) - A non hazardous area is an area in which an explosive atmosphere is not expected to be present.

As per IEC60079-10-1 and AS/NZS 60079.29.2:2016

Lift Shaft Wells

Oxygen sensors are often placed in lift shaft wells to measure the atmosphere prior to entry. Problems arise due to the pressure changes in the left shaft well due to the air movements associated with the lift.resulting in false alarms . There is also an issue associated with safe work permits for access into the lift shaft area when the oxygen sensor requires calibration or replacement. The GDA 4500 system uses a vacuum pump (dc brushless) , a flow fail mechanism and a sensor  to extract the gas via a 6mm ID tubing. The Nylon tube is fitted with a filter element to provide dust filtering and prevent mycological build up in the sampling line.

Designed, Manufactured and Supported in Australia.

Confined Space Gas Monitors

Confined spaces have a high risk of poisonous gases and man-down incidents caused by oxygen depletion. Responders or workers are required to be protected by ongoing, continuous atmospheric monitoring. SENKO Gas Detection Australia's portable gas detectors are built to protect you and your staff complying with Australia regulations. With IP 67 Waterproof and IEC Ex Approved Explosion proof casing, data logging, simple set up and calibration. The SENKO Gas Detection Australia Line of Portables are ready to go when you are.

Notes

  • Flammable Catalytic Sensor
    • Poisoning: some compounds will decompose on the catalyst and form a solid barrier over the catalyst surface. This action is cumulative and prolonged exposure will result in an irreversible decrease in sensitivity. The most common of these substances are: volatile lead or sulphur containing compounds; silicones; phosphates.
    • Inhibition: certain other compounds, especially hydrogen sulphide and halogenated hydrocarbons, are absorbed or form compounds that are absorbed by the catalyst. The resultant loss of sensitivity is temporary and in most cases a sensor will recover after a period of operation in clean air

 

  • Flammable NDIR Sensor
    • Caution: The infrared LEL sensor used in the MGT cannot detect hydrogen and acetylene. For applications involving these combustible gases, a catalytic LEL sensor is recommended.

 

  • Electrochemical Sensor 
    • Poisoning: Senko sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.

 

  • Oxygen Electrochemical Sensor
    • Poisoning:  Acid gases such as CO₂ and SO₂ will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO₂. Senko oxygen sensors are not suitable for continuous operation in concentrations of CO₂ above 25%.

CALGAS : Calibration Gas

To test and maintain accuracy gas detection systems require regular testing and calibration. GDA can provide you with a complete line of calibration equipment to calibrate all of our gas sensors and detectors. Our calibration gas cylinders all come with N.I.S.T. certification and ISO 17025 approval so you can be confident that you will receive gas with the highest accuracy levels.
