Product Details

Product description：

ADT300W-O2Fixed oxygen concentration detectorIt is a gas detector newly created by Outit Technology on the basis of the original, using * sensors and a new 32-bit low-power processor; The dashboard display interface displays both numerical values and progress bars, presenting a beautiful and elegant appearance; The circuit adopts 4-layer wiring, which has stronger resistance to weak signals and interference; Independent high-precision imported 16 bit AD chip and * signal processing algorithm, with higher and more stable measurement data accuracy; 4~20mA, RS485, 200~1000HZ multiple output signals can be selected, making it easy to connect to various alarm controllers, PLCs, DCS and other control systems; Explosion proof structural design can be applied in various hazardous industrial sites; The product is widely used in various fields such as petroleum, chemical, metallurgical, power, municipal, fire protection, industrial production, university scientific research experiments, and exhaust environmental monitoring.

Product Features:

◆ * High performance sensors with high measurement accuracy, good repeatability, and long service life;

Adopting an independent 16 bit AD chip and a 4-layer circuit board design, it has stronger resistance to weak signals and interference;

◆ mg/m³、 Multiple units such as ppm, VOL, and LEL can be selected when leaving the factory;

◆ Equipped with an embedded 32-bit ultra-low power processor and signal processing algorithm, it has fast response speed and stability;

◆ Automatic protection function against high concentration gas impact, with factory reset settings to prevent misoperation;

The instrument is equipped with an infrared remote control, which can be operated through the remote control without opening the cover, making it simple and convenient;

◆ Three wire system with 4-20mA, RS485, 200~1000HZ signal output options, relay output, data recovery, data storage and other functions;

Two cable entry ports for easy on-site installation;

◆ Independent chamber structure, easy sensor replacement, no need for on-site calibration;

The mechanical design of the air chamber adopts high-quality high-strength aluminum profiles, which are wear-resistant, corrosion-resistant, and suitable for complex and harsh industrial environments. The reasonable and scientific air chamber design ensures the accuracy of real-time monitoring by sensors;

The explosion-proof level is Exd II CT6, certified by the National Explosion proof Electrical Inspection Center.
