EN-7660 Intelligent Dew Point MeterDetailed product description：

The EN-7660 intelligent dew point meter adopts original imported detector and microprocessor technology, with functions such as large screen LCD display, upper and lower limit alarm, standard signal output, relay contact alarm output, self check, self correction, etc; It can directly measure atmospheric dew point and absolute moisture (ppm). The detection components of the instrument are imported with original packaging and have anti condensation, anti dust particles, and are not affected by oil and gas, most chemical gases, and flow rate. This instrument also performs precise compensation calibration on the dew point sensor, resulting in an accuracy of dew point measurement better than ± 2.0 ℃ and a resolution of 0.1ppm. Suitable for continuous monitoring of trace water concentration in gases such as air, nitrogen, hydrogen, argon, etc.

The main features of EN-7660 intelligent dew point meter are:

Original imported capacitive dew point measurement transmitter, accurate measurement, stable and reliable;
Equipped with low dew point measurement automatic calibration technology, it automatically corrects zero drift and has good long-term stability;
Resistant to dust particles, unaffected by oil and gas, and most chemical gases;
Anti condensation, very suitable for dew point measurement of pipelines that are frequently opened or stopped;
Unique air path design, with good air tightness, impermeability, and water absorption resistance;
Can switch between displaying atmospheric dew point and ppm value;
Full Chinese operation menu, human-machine dialogue, user-friendly interface;
Large screen dot matrix LCD display;
Real time clock displays date and time;
The upper and lower limit alarm points can be set arbitrarily within the full range;
Equipped with timed automatic storage function, historical data can be viewed at any time;
Equipped with a paperless recorder function, it automatically records the dew point change curve over time
Has 0~10mA or 4~20mA standard signal output;
Equipped with an RS-232 communication port, it can connect to a serial printer or achieve bidirectional communication with a computer.
