MBW 973

High Pressure Option
The 973 is available with 10 or 20 bar inlet ranges for use in pressurised applications. The high pressure variants include higher specification pressure sensors, stainless steel sample tubing and the removal of the sample pump fitted to the standard instrument.

Color Touch Screen
The 973 uses a full color active matrix liquid crystal display with an integral touch panel. It has a high contrast ratio and a wide viewing angle for easy readability. Data is displayed in large easy to read fonts. Using the on screen buttons and menus, you can easily configure each line of the display for a variety of humidity, temperature, and pressure parameters that may be viewed in either SI or non-SI units. A simple touch of a button toggles any parameter between numeric or graph format.

Dew/Frost Determination
User configurable via the full color active matrix LCD touch screen, the 973 may be configured for measurement of dew point, frost point, relative humidity, and other parameters. The ForceFrost™ feature ensures reliable differentiation between super-cooled dew and frost.

Optimal Response Injection System (ORIS™)
ORIS uses a controlled addition of water vapor to accelerate the formation of a condensate layer and therefore reduce analysis times. Once a layer is formed, ORIS is disabled to allow the gas flow to reach a balance of condensation and sublimation on the mirror surface. At -60 °C Frost Point, ORIS reduces stabilisation time by up to 90%.

Verifiable Calibration
Easily check the 973 calibration at any time using the built-in Ice Test function, providing instant verification of system accuracy and integrity.

Connect and Go
The 973 is supplied ready for immediate use complete with built-in pump (not high pressure versions), flow meter, pressure sensor, and external temperature probe. PC connectivity for remote data collection is easy with the simple yet robust protocol of the bi-directional RS-232 port.
