Selective detection of water
The Berghof EasyH2O® combines
thermal evaporation of water with a selective, electrochemical
water sensor to create an innovative method of water
analysis. The water is evaporated out of the sample
in a programmable oven and is fed to the sensor by means
of a carrier gas flow stream. The water is slowly evaporated
using the temperature profile of the heating program
and the bonding forms of the water are differentiated.
The ambient air is sucked-in and dried to be used as
the carrier gas. Therefore, no special chemicals or
carrier gases are required to operate it. Nitrogen can
be used as an alternative carrier gas, for example in
order to prevent decomposition reactions with oxygen.
The entire process is software-controlled and runs automatically.
Coulometric P2O5 sensor
The core of the device is the coulometric P2O5 sensor.
No special or toxic chemicals are required to operate
the phosphorus pent oxide measuring cell. This makes
the system environmentally friendly and reduces the
operating and disposal costs. Operating personnel require
no special training on how to handle toxic chemicals.
