Certified for comparison measurement in ultrapure water up to 20 μS/cm

Ultrapure water is used in sensitive areas of the pharmaceutical and food industries and in process engineering. Calibration of process conductivity measurement is obligatory for these applications.

Since calibration solutions with very low conductivity are unstable, there is no standardization for conductivities below 74 μS/cm.

Conducal is a reference unit that permits the calibration of process measuring devices by means of a certified comparison measurement.

• Calibration of quality-relevant process measurements in the ultrapure water range up to 20 μS/cm
• Checking of in-line measurements in the process, e.g. after inspections or interruptions in operation
• Checking of conductivity measuring equipment primarily in the pharmaceutical and food industries
• Checking and calibration for product quality assurance, e.g. in semiconductor production

• Factory calibration traceable to SRM by NIST and DAkkS
• Factory calibration of Conducal system according to ASTM D-5391-93
• Flow assembly with adjusting and monitoring functions according to ASTM D-5391
• Flexible applicable in the field thanks to:
• battery-driven system (independent of power network)
• robust case IP67 with external power connection
