To ensure you get the longest life and most accurate measurements, learn how to clean, calibrate, and maintain your growing tools correctly.
View Maintenance GuidesIt is crucial to learn how to clean, calibrate, and regularly maintain your Bluelab tools to ensure accurate readings and extended product life. Over time, dirt, oils, nutrient salts can build up on sensors, affecting performance and accuracy. By caring for and calibrating your Bluelab tools correctly, you help ensure optimal sensor function and support healthy, consistent plant growth.
Calibration of Bluelab products is the process of adjusting your pH or EC meters and pens using specific EC or pH meter calibration solutions. This process aligns the instrument’s readings with known reference values, ensuring measurement accuracy.
Calibration is recommended once a month, or more frequently if the instrument is used heavily, for continuous monitoring or used with organic soils or nutrients. Many Bluelab products provide an on-screen calibration indicator to help you stay on schedule. After successful calibration, a confirmation check mark appears on the display. This check mark remains visible for 30 days, after which it disappears to indicate that recalibration is required.
Extend the lifespan and performance of your Bluelab equipment through correct care, regular calibration, and routine maintenance. Proper handling ensures your tools continue to deliver accurate, dependable measurements throughout their working life.

Calibrating to two points ensures greater accuracy in pH measurements. It allows the pH Probe to be calibrated at both a neutral point (pH 7.0) and either a low point (pH 4.0) or a high point (pH 10.0), depending on the expected range of readings. This two-point calibration helps to account for any non-linearity in the probe's response across the pH scale, providing more reliable and accurate readings. Always calibrate the pH Probe with pH 7.0 first, then to pH 4.0 or pH 10.0.
KCI or Potassium Chloride is a storage and hydration solution for pH Pens and pH Probes. It ensures that the pH Probe is stored in ideal conditions when not in use. Store in KCl when not in use. Fresh application is recommended once per week.
pH drift. Without frequent calibration, your pH meters will give inaccurate readings. Overtime the pH glass and junction chemically change causing reading to shift.
Rehydrate for 24 hours in KCI Storage Solution. Then recalibrate the probe.
If your EC or ppm readings are different than expected or won't stabilise, check using 2.77 EC solution.
If it has been 30 days since the last calibration, your readings won't stabilise, or the values are significantly different than expected.
To keep your pH Probe clean, rinse the probe with clean water after each use. Follow the Bluelab cleaning procedure, then store your pH probe correctly in Bluelab KCl Storage Solution so it stays hydrated and accurate.
Yes. Bluelab pH Probes and Conductivity (EC) Probes are fully waterproof and designed to be completely submerged in water during normal use. They can be safely dunked or placed directly into reservoirs, nutrient solutions, or water samples while taking measurements.
