Methanol Gas Detector Singapore
Methanol (CH3OH) is the simplest alcohol. It is colourless, flammable, light and volatile liquid with a distinctive odour similar to that of ethanol. Unlike ethanol, methanol is highly toxic and unfit for consumption. Methanol is extremely toxic to humans if ingested or if vapours are inhaled. By drinking as little as 1 to 4 oz can cause irreversible injury to the nervous system, optic nerve damage lead to blindness or even death and should never come into contact with the skin. Birth defects have been observed in the offspring of rats and mice exposed to methanol by inhalation.
Methanol is released to the environment during industrial uses and naturally from volcanic gases, vegetation and microbes.
Methanol is primarily used as an industrial solvent for inks, resins, adhesives, and dyes. It is also used as a solvent in the manufacture of cholesterol, streptomycin, vitamins, hormones, and other pharmaceuticals. Methanol is also used as an anti-freeze for automotive radiators, an ingredient of gasoline (as an anti-freezing agent and octane booster), and as fuel for picnic stoves. Methanol is also an ingredient in paint and varnish removers. It is also used as an alternative motor fuel.
Methanol is a very poor lubricant and causes corrosion to the valve stem, guide or valve seat. Metals and soft materials in the fuel systems get rusty when in contact with methanol.
Function of Methanol Gas Detector
Methanol gas detector is to detect methanol concentration gas leak by using electrochemical methanol sensor assembled inside the detector. It has high sensitivity level and responds accurately. If the gas leak level reaches an alarming level that exceeds the limit set in the detector it will trigger an alarm and the occupants are to leave the site.
Portable Methanol Gas Detector
Portable methanol gas(CH4O) detector is applied to detect methanol gas leak detection and activate the alarm. It can test the methanol content accurately by using the electrochemical methanol sensor. The signal stability is good. It has high sensitivity level and provides the functional data with high precision, etc.
The method of detection is dispersive and is optional pump suction type. The screen display is LCD backlit display and the precision is ≤±3% (F.S.) with audio and visual alarm
The sensor design shall incorporate an internal intrinsically safe barrier circuit which eliminates the requirement for a flame arrestor and allows for direct sample contact with the sensing element. The sensor shall provide an industry standard 4-20 mA output and a serial communication interface utilizing the MODBUS RTU protocol via the RS-485 connection. The analog and serial data shall be available simultaneously. Large capacity rechargeable lithium battery can work continuously for a long time
