The detector can be mounted on a vertical/horizontal tube or wall.
Leak source and leak accumulation should be identified and used in selecting the optimum detector mounting location within the area.
Identify air current, wind patterns within the protected areas when choosing installation point.
Installation height is determined by density of measured gas.
Note: Locations near excessive heat or vibration sources should be avoided if possible.

There are a number of different types of sensors used for gas detection. The choice of sensor depends on:
the gas to be detected
the expected range of concentration
whether the detector is fixed or portable
whether the detector is point or open path
|Catalytic||The operating principle is that heat is generated during the catalyzed reaction between the gas and oxygen in air. The resulting rise in temperature of the catalyst bead causes a change in electrical resistance of a platinum wire embedded in the bead, also acting as the heater, which is a measure of gas concentration.|
|Combustible gas detection, 0~100%LEL|
|Product model: GT-1030/1031-TF, and GT-1030/1031-TS, etc.|
|Electrochemical||The operating principle is that the gas diffuses through a permeable electrode to its interface with the cell’s electrolyte. Here electrochemical reactions take place which alter the electrical characteristics of this electrode. Measurement of these electrical parameters with respect to other electrodes within the cell give a signal proportional to the gas concentration.|
|Oxygen and toxic gas detection, in ppm level|
|Product model: GT-1121, GT-1020-DF, and GT-1020-TF, etc.|
|Photo Ionization||The operating principle is that an ionized gas will conduct an electrical current in proportion to the number of ions present. Hydrocarbon gases and vapors are easily ionized and the current flow produced is easily measured.|
|VOCs and some inorganic gas detection, in ppm level|
|Product model: GT-1040.|
|Infrared||The operating principle is based on the absorption of infrared light by certain molecules which are detected by a decrease in transmitted radiation over a beam path.|
|Detect CO2 and methane, and halohydrocarbon gas such as chloromethane|
|Product model: GT-1020-IR, and GT-1030/1031-IR.|
