Through Vaisala's patented non-dispersive infrared (NDIR) technology and patented vacuum gas extraction system we are able to achive the best long term stability, reliability and measurement performance on the market with no false alarms and nothing to service or maintain. 

Key Benefits

A Monitor That Works Anywhere
Stainless steel pipes, IP66-rated, temperature controlled housing, as well as a magnetic pump and valves provide superb performance and durability – from the arctic to the tropics. There are also no consumables to service or replace.
No More False Alarms
The monitor’s IR sensor is based on Vaisala core measurement technology and critical sensor components manufactured in Vaisala cleanrooms. Vacuum gas extraction means no data fluctuation due to oil temperature, pressure, or type, while the hermetically sealed and protected optics prevent sensor contamination. The end result? A monitor that completely eliminates false alarms.
Intelligent Features for Hassle-free Monitoring
The monitor has a web-based interface that completely eliminates the need for additional software, and the device can be installed quickly – just connect the oil, power and data connections, and it’s ready to go. And in case of a disturbance like a power outage, self diagnostics allow the monitor to adjust itself.
