FN304C Explosion-proof Dew-point Meter adopts imported capacitive dew-point sensor with high response speed and sensitivity and easy and simple to operate. It is applicable to the measurement of trace moisture content in various gases and suitable for a variety of locations needing 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 aluminum oxide capacitive dew-point sensor with high response speed and sensitivity;

Large-screen 320×240 lattice LCD, with clear and concise 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;

Several kinds of display interfaces, meeting the operation needs of customer to the largest extent;

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;

Upper/lower limit alarm output can be set at will within the range;

Standard RS232 or RS485 communication interface available for two-way communication with computer;

Isolated explosion-proof case adopted, so that the instrument can be directly installed on the site.
