MBW designs and
sells custom humidity, temperature and pressure solutions, including
humidity generators and chilled hygrometers. MBW was founded in 1962
and is a privately-held company headquartered in Wettingen, Switzerland.
Our product line is
jointly developed with our US partner, RH Systems, and manufactured in
Switzerland and in the United States. We provide the design expertise
in chilled mirror technology and high precision analogue electronics.
Our products are
used in national metrology institutes and commercial laboratories
around the world, and we are proud of the elite companies who have
chosen our products.
We provide a variety of products for humidity measurement, humidity generation, and temperature measurement to fit your needs.
Overview
The Model 973 Dew
Point Mirror is a portable instrument equipped with an integral
measuring head for both spot and continuous measurement of Dew/Frost
point and temperature in air and gas mixtures. Based on the chilled
mirror principle, the 973 ensures direct and accurate humidity
measurement.
Color Touch Screen
The system 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.
Verifiable Calibration
Easily
check the calibration at any time using the built-in Ice Test function,
providing instant proof of system accuracy and integrity.
Connect and Go
The system is
supplied ready for immediate use complete with built-in pump, 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.
