pH Measuring Module
Item/designation
Impedance converter
We recommend the installation of the impedance
converter in order to prevent negative influences to the
measurement signal of pH-measurement due to electrical
fields of near live wires, dirt or moistures.
The impedance converter is also used to short-out higher
distances (more than 10 m) between measurement chain
and measurement unit.
The impedance converter is screwed onto the
measurement chain directly.
The delivery performance includes also an battery (live
approx. 5 years).
