Digital Fine Differential Pressure Sensor Model GTI 135/GTI 145

The aerosol photometer Model 3990 is a forward light-scattering, linear digital photometer. The primary application for the 3990 is integrity/leak testing of HEPA/ULPA filtration systems with a compact and light weight, rugged die cast construct, easy to work, portable and friendly large bright true color 5.6inch LCD providing ease of operation and readability.
Because of the Aerosol Noise Suppression function, the testing data will be more stable. The build-in thermal printer supports long term thermal paper printing, real-time data reading and printing at site.
