Humidity- temperature probe

checking of measuring accuracy of the humidity measurement part can
be done by end user with the salt reference cells available as special
accessories. The cross checking must be done in temperature stable
environment. The detailed instructions for calibration are available for
download at our homepage.
Alternatively, the measuring system can be sent to our calibration labo-
ratory for cross checking or calibration.
Internal data transfer
The communication between PC and measuring probe happens seri-
ally by means of a COM port emulation. Therefore, it is very simple to
link the measurements to your own software, programming knowledge
presupposed.
For the used USB UART FTDI 232 Interface, drivers are available for
Linux, MAC or even PDAs.
The interface works on a data rate of 4800 Baud, 8 Data bits, No parity
and one Stop bit. Further information on data protocol can be downloa-
ded from our website.
Accessories (Optional)
Humidity reference cells
The B+B Humidity reference cells serve as humidity standards, in or-
der to create stable humidity values for experimental purposes or for
calibration of the measuring device. The accuracy possible under stab-
le temperature environment conditions is in the range of ±1 % relative
humidity. The working principle is based on a saturated salt solution,
over which a specic relative humidity value adjusts itself. The cells
also contain a semi-permeable Teon membrane (diaphragm) through
which the salt solution is separated from the measurement area.
Protection lter
The stainless steel probes can be tted with various types of protection
lters, if required. The PE protection lter is water repellent, the stain-
less sinter lter is robust, temperature resistant and protects the sensor
element against dust.. The lter with tip is suitable for measurement in
