A 718AP is a self-contained detector developed for the unattended easy detection of flammable and combustible gases, vapors and mists or oxygen in concentrations ranging from 0 to 50,000 ppm (parts per million). This state-of-the-art detector is suitable for both occupational and environmental health and safety applications. This detector uses a semiconductor-based, catalytic-type sensing element which is designed to respond to a wide range of common flammable gases and vapors. It has two built-in, two-stage ranges, normal and peak, and can be monitored locally or remotely with wireless communication.

A 718AP can monitor the air for combustible, flammable gases and vapors. It can also be used to detect oxygen concentrations in a range of 0 to 50,000 ppm. Gases are detected through the use of a semiconductor-based, catalytic-type sensing element. The highly sensitive sensing element is designed to meet the various requirements for high accuracy and quick response. The detector features two distinct, two-stage ranges to enable accurate and rapid measurement of hazardous gases.

A 718AP contains advanced safety features such as a built-in self-diagnostic system that monitors the sensor, calibration, and all other parts of the detector. This self-diagnostic system can detect possible gas leaks and other problems quickly and accurately. It also features an internal temperature gauge and onscreen display that shows the air or gas concentration detected. The device is also self-calibrating, allowing it to stay calibrated without manual adjustments.

The A 718AP is designed for both industrial and commercial working environments. It can be used in a wide variety of industrial fields, including chemical plants, oil refineries, and oil rigs. It is also suitable for indoor use in areas such as laboratories, schools, hospitals, and manufacturing facilities. It is highly regarded for its reliable and accurate readings and is easy to use and maintain.

The working principles of the A 718AP are based on the catalytic combustion method. This method is used to measure the concentration of flammable and combustible gases as well as oxygen concentration. The sensor contains two chambers, one containing a specified combustible gas, and the other a permeable catalyst. When the combustible gas is present in the first chamber, the catalyst ignites the combustible gas, creating an exothermic reaction which is substituted by a defined temperature increase in the sensor. This temperature increase is registered by the sensor and is used to calculate the gas concentrations in the air.

In conclusion, the A 718AP is an advanced and reliable gas detector suitable for both industrial and commercial purposes. The detector can accurately detect and monitor combustible and flammable gases, vapors and mists as well as oxygen concentrations in a safe and efficient manner. And it features a self-diagnostic system, self-calibration capability, and an integrated temperature gauge, making it an ideal choice for use in industrial, commercial and even residential applications.
