Probe usage & Calibration tips

Accessories: rinse container, calibration container, calibration standard, DI water
Prior to placing the probe into a standard:

• Remove the transparent protective ring (1).
• Rinse in DI water and gently shake off excess water.
• Immerse the probe in rinse container ensuring that probe’s holes (3) are completely submerged. Swirl and remove.
• Immerse and swirl the probe several times to prime the probe.

Calibration tips

• Ensure the probe is correctly plugged in.
• Use fresh standards with a value close to that of the sample.
• Pour fresh standard in calibration container, immerse the probe, gently swirl, and remove.
• Immerse and swirl the probe several times.
• Gently tap the probe to remove trapped air bubbles.
• Wait for the temperature to stabilize and the probe to acclimate to the solution.
• Calibrate frequently and discard standard after use.

Conductivity measurement tips

• Work with recently calibrated probes.
• Substitute calibration standard with measured sample and follow calibration recommendations.
• Use the arm holder for easy probe transfer in and out of container and correct probe positioning, away from container walls or bottom.
• TDS measurement: use correct TDS conversion factor for measured sample.
• Record measured data once the reading is stable.
• Clean and rinse off any residual sample on the sensors (2) after measurement to keep the probe in optimum condition.
