produced being directly proportional to the mass
of moisture absorbed (Faraday's law of electro-
lysis). The response of such an instrument
obviously depends on the flow rate of gas, which
is set and controlled accurately at a predeter-
mined rate so that the current measuring meter
can be calibrated in vppm moisture. Details are
given in Chapter 19.
