FN104B Portable Dew-point Meter adopts imported dew-point sensor with high response speed and sensitivity; it is powered by AC/DC and will be an intrinsically-safe explosion-proof instrument when powered by DC; the portable design makes operation easy and simple; the meter is applicable to the measurement of trace moisture content in various gases and suitable for a variety of cases requiring quick moisture content measurement and explosion protection.

Application fields:

Petroleum and chemicals, natural gas, gases for industrial purposes, semiconductor industry, drying industry, food industry, electric power industry, mechanical manufacturing, air separation industry, and pharmaceutical industry

Instrument characteristics:

Imported capacitive dew-point sensor featuring quick response and high sensitivity;

128×64 lattice OLED display, self-luminous, with wide angle of view (above 160℃) and Chinese operation menu;

Simultaneous display of dew point, volume ratio (PPm/V), and absolute humidity (mg/m3); intuitive readings eliminating the need for manual meter reading;

AC/DC power supply automatic switchable; lithium-ion battery available for continuous operation of over 12 hours once fully charged;

Automatic storage of measured data at a time interval that can be set at will; the recorded data can be displayed in the form of curve or list for the convenience of browsing and viewing;

Alarm point can be set at will within the range;

Built-in air extracting pump and external filter can be added upon selection.
