MBW-973 Precision Dew Point MeterDetailed product description：

The MBW-973 precision dew point meter is a portable precision dew point meter manufactured using cold mirror technology. It can simultaneously perform point dew point measurement, continuous dew point measurement, and humidity measurement in air and mixed gases.
The system uses a full-color active matrix LCD display and an enhanced touch screen. The screen has high contrast and a wide viewing angle, making it easy to read. Touchscreen buttons and menus allow users to easily configure each line of display, such as humidity, temperature, and pressure parameters, which can be displayed in either the International System of Units (SI) or Non SI units. Simply touch the corresponding button to switch between digital mode and chart mode.
Users can display measurement parameters through a full-color matrix LCD, while 973 can display dew point, frost point, relative humidity, and other parameters. The ForceFrost feature ensures reliable differentiation between extremely cold dew points and frost points.
The system has complete equipment that is currently in use, including built-in pumps, flow meters, pressure sensors, and external temperature probes. The connection with the PC may be easily accomplished through bilateral RS-232 ports and transmission protocols to collect data from the operating end. Using the freezing point test button to simply check the calibration status of the instrument can directly confirm the accuracy of the system.
