Technical content
Ultrapure water is used in sensitive areas of the pharmaceutical and food industries and in process engineering. Calibration of process conductivity measurement is absolutely necessary for these applications. Conducal is a reference unit that permits the calibration of process measuring devices by means of a certified comparison measurement. It can be used as follows:
- Calibration of quality-relevant process measurements in the ultrapure and pure water range up to 20 μS/cm
- Calibration of in-line measurements after inspections or interruptions in operation
- Calibration of measuring systems in the pharmaceutical and food industry
- Calibration to ensure product quality, such as in the semi-conductor industry, for example Your benefits
- Factory calibration traceable to NIST and PTB
- Factory calibration of the Conducal system according to ASTM D-5399–93
- Flow assembly with adjustment and monitoring functions according to ASTM D-5391
- Flexible use in the field
- Easy to clean thanks to polished surfaces
- Battery-operated system (independent of power network)
- Robust IP67 case with external sensor connection Products Solutions Services Technical Information Conducal CLY421 Conductivity calibration kit for ultrapure water

With this measuring arrangement, the sensor is not removed from the process. Please ensure that the composition of the medium and the temperature at the process measurement point and comparison measurement point are the same. This is ensured by:
- Using short hose connections
- Waiting until the temperature in the flow assembly adjusts to match the process temperature. Advantage: Process remains hygienic Disadvantage: Waiting time for temperature harmonization

7 Inlet
The flow assembly included with the calibration kit has two installation slots for conductivity sensors and therefore enables a direct comparison measurement. Advantages:
- No temperature difference, therefore no waiting time
- Absolutely identical medium Disadvantage: As the process must be opened, the medium can become contaminated Dependability Flow assembly The Conducal calibration kit is fitted with a special flow assembly for the Memosens CLS15E conductivity sensor.

8 Flow monitoring
The medium must be bubble-free to prevent false conductivity measurements. Outgassing can occur when the medium releases tension, i.e. also in the bypass arrangement described. Thanks to the bubble trap integrated in the flow assembly, the medium around the conductivity sensor stays bubble-free. A0050890 4 Medium supply in case of comparison measurement with bypass
1 Vent hole
2 Inlet
3 Second installation slot
4 Lateral bore hole
When the flow assembly is used with the bypass setting, the second installation slot is used as a hydrocyclone. Inflow is tangential, producing a turbulent flow, so any bubbles can escape through a vent opening at the top. The medium is conveyed to the actual measurement chamber via a lateral bore hole.
Controlled conditions with flow monitoring When calibrating with Conducal according to ASTM D-5391, a minimum flow specified by the sensor manufacturer must be observed. The flow assembly in the Conducal calibration kit is designed for conductivity calibration according to the standards:
- Bubble trap (for bypass measurement)
- Float-type flow measurement
- Flow adjustment with control valve
- Temperature stability up to 100 °C (210 °F) 2 3 4 5 A0050892 5 Schematic of bypass arrangement

The flow assembly is equipped with a flexible holder for mounting on round and square pipes. This makes comparison measurements in the field safe and easy. A0050893 6 Holder
