Selection and Ordering Recommendations

When selecting spare parts, please match the corresponding order number according to actual installation conditions, measurement range, and environmental parameters. All spare parts are marked with a recommendation level of A, indicating preferred selection. Calibration solutions need to be replaced regularly to ensure calibration validity.

  • Confirm pipe size and connection thread, and select matching sleeves or adapters.
  • Select the appropriate concentration of calibration solution according to the measurement range, such as 74.0 uS/cm or 1.406 mS/cm.
  • For high-temperature and high-pressure applications, the CYA21 flow-through holder is recommended, withstanding up to 100°C and 16 bar.
