Oil Mist Detector
Oil mist is described as tiny droplets of oil in the air. They have a low ignition temperature and pose a large fire hazard. Oil mist are developed in case of oil leakages, and can be formed if a minor oil leakage occurs in pressurized oil lines or if an oil leakage results in evaporating oil hitting a very hot surface. Oil leakages often occur in engine rooms, pump rooms, and other rooms with hydraulic installations or oil systems under pressure.
In order to avoid fire it is necessary to prevent the formation of oil mist. If you install an oil mist detector, it will detect the formation of oil mist before it reaches a dangerous level. The G26 Ambient Oil Mist Detector is an acclaimed double-pass opacity monitor. The system uses the latest green laser technology, and can be configured up to 8 detectors per monitor.download catalogue

G362x Stack Gas Oxygen Analyzing System. The G3620 Stack Gas Oxygen Analyzing System offers a decisive tool for optimizing boiler efficiency and reducing the oxygen content of exhaust gas. The system is installed in the stack close to the boiler and measures under actual flue conditions. The sample is analyzed in situ without being passed through vulnerable sampling lines.
The fuel-air ratio in the burner is crucial to optimizing the combustion and boiler efficiency. With the G362x you can typically optimize combustion and save 3-5% fuel – in some cases even more.download catalogue
G3631 Ambient Oxygen Analyzer. The ambient oxygen analyzer measures the content of oxygen with concentrations up to 21.0 %. The system is designed to measure the content of oxygen in the atmosphere in inert gas rooms such as engine room compartments, rooms for inert gas system or accommodation area, or in simulated altitude training rooms.
The system uses a zirconia sensor. Zirconium dioxide sensors have long been established as industry standards, but the G3631 uses a new type of zirconia sensor, which can be used in a wide range of applications.download catalogue
G41xx NOx/O2 Analyzing System. Green Instruments' NOx analyzer - the G41xx NOx/O2 Analyzing System - is a direct in situ gas analyzer that monitors NOx and O2 concentrations in emission gas. The NOx analyzer provides a cost-effective solution to help fulfill tightening emission regulations as well as supporting the most effective operation for all types of combustion processes. It is designed to meet the challenging requirements for monitoring the inlet and outlets of selective catalytic reduction systems (SCR) on all types of combustion sources.
The G41xx NOx analyzer uses a zirconium oxide (ZrO2) sensor with multiple diffusion cells. The sensor is small and robust and can be installed directly on the stack without special protection. The technology of the GI NOx analyzer allows real-time measurement of NOX and O2 on wet basis at high temperatures. This avoids sampling lines and multiplexing systems, coolers and converters with all their disadvantages.download catalogue
