The AHHOI - Infrared Water-in-Oil Sensor is a development by Martechnic® using the IR principle to detect water in lubricants of different nature and application. It measures all three possibilities of water being present (saturated, emulsion and free water) in molecular form up to 10000 ppm / 1.0 Vol.% and operates on a bypass system.

It is important that every device is calibrated on the respective oil.

The measuring method is applied for a patent and the device has a type approval from Germanischer Lloyd.

The system has to be connected to the oil system of the machinery with a pressure range between 1 to 10 bar. The sensor of the system is protected by an inbuilt oil filter and should be operated at a constant pressure of 1 bar which is managed by a constant pressure reducing valve.

The AHHOI requires a pressure free outlet (atmospheric drain) and incorporates a flush through system for cleaning.

The system is housed in a A3 sized IP 54 steel box and requires 100 - 240 VOLT and has both serial and analogue outlets (0 - 20 / 4 - 20 mA) available.
