impedantie converter voor pH / Redox- insteek elektroden (202995)

The impedance transformer transforms the high Ohm signal of the pH electrode (up to 1,000 MOhm) into a low Ohm signal (< 1 kOhm). The use of an impedance transformer can also be advantageous in conjunction with a metal electrode.
The impedance transformer is directly screw-fitted onto the electrode head. This largely prevents malfunctions resulting from soiling, moisture or electrical interference of current carrying cables. As a connection cable, a commercially available coax cable between impedance transformer and transmitter is sufficient. This allows longer distances between measured value transducer and transmitter without problems. Independence of the impedance transformer from an external power supply is achieved by the installed lithium battery.
