YSI IDS 4320 digital conductivity/temperature probe for the YSI MultiLab. The IDS 4320 probe is designed for ultra-pure water applications and cannot be calibrated by the user, although the probe is factory calibrated.
The IDS sensors automatically store their unique serial number and calibration data. In addition, they also digitally process the measurement signal. The IDS sensors can be moved from instrument to instrument and maintain their calibration data and transmit that information to the new instrument.
