Warner Instruments has introduced the HiZ-223 dual-channel differential spectrometer.
It is a high input impedance amplifier featuring two small active headstages that allow the first stage of amplification to take place at the electrode site.
The amplifier is suitable for measurements using high-resistance ion-selective microelectrodes.
The design reduces shunt capacity and minimises electrical interferences such as electrostatic noise and motion artifacts. The probe housing includes a signal-driven guard that further reduces noise and stray capacity.
It has a probe test port that permits testing the electrode as well as setting the probe leakage current. A standby mode is included and should be used when attaching microelectrodes or electrode holders to the probe input.
