D7 Connection Specification
Technical Data and Functions
Digital connection cable.
The voltage of the probe is measured by an A/D converter integrated into the ALMEMO® D7 plug. Extension cables and the measuring device itself have no influence on the measurement accuracy.
Galvanic Isolation to the ALMEMO® V7 measuring device.
It is possible to operate several pH probes simultaneously in the same sample solution on one measuring device without influencing each other.
Compensation of the temperature dependence of the probe.
To compensate the temperature dependence of the probe, the temperature of the sample solution can be entered manually. The connection cable ZYD7 40-Akx additionally features a temperature sensor. As a result, the measured temperature value will be used for automatic compensation.
Comparison of the pH probe possible at three points.
The comparison will be saved at pH 7 as well as at one point in the acid range and at one point in the alkaline range. The values of the reference solutions can be specified as set points.
