Product application:
Suitable for rapid measurement of dust particle concentration in boiler combustion system flue gas, especially suitable for solid fuel systems such as wood particle boilers, biomass boilers, coal-fired boilers, etc.
Product Description:
STM225 is a portable smoke analyzer equipped with the latest technology and Bluetooth communication function. It uses laser measurement principle and can read the concentration of dust particles in real time. Laser light sources have a long lifespan, excellent stability, and precision without damage.
The STM225 consists of a measurement host and a sampling system. The instrument's built-in dual beam measurement system is integrated into two separate measurement chambers, which are used to measure the concentration of fine dust and larger particulate matter dust in the flue gas. Each measurement lasts for 15 minutes and the automatically calculated average value is displayed on the screen.
