Sensonic 300
Sensonic 400

Sensonic 300/400 is a high quality gas monitor. The device is produced using the latest technology. Due to the modular design of Sensonic 300/400 it is possible to meet the individual client's expectations by adjusting it to performing particular measurements, such as concentration of various gases, pressure, temperature and a number of boiler parameter measurements.

The monitor is in particular designed for flue (boiler) gas analysis, but it can be used for different purposes (such as producing biogas from garbage and animal excrements) as well.

Each Sensonic 300/400 gas monitor enables the user to measure concentrations of 3 or 4 gases. Additionally the device can present the measurement results on the liquid crystal displays and up to eight analog outputs. Independently of the built-in display equipment there is also the possibility of reading the measurement results and changing the settings with the help of the computer program provided.
