Bluelab Probe Care Kit – pH & Conductivity is a kit containing everything needed to clean, hydrate and calibrate your pH meter probe, as well as clean and test your EC meter probe (electrical conductivity meter):

• Instructions on how to care for the probes of your meters
• 2 x Bluelab pH 7.0 Calibration Solution - Sachet 20ml
• 2 x Bluelab pH 4.0 Calibration Solution - Sachet 20ml
• 2 x Bluelab pH Probe KCl Storage Solution - Sachet 20ml for single use
• 2 x Bluelab 2.77 EC Conductivity Standard Solution Sachet 20 ml for single use
• pH probe cleaning solution
• EC probe cleaning solution
• pH probe cleaning tool
• EC probe cleaning tool

1. Your instruments' measurements are only as accurate as their probes are clean. Accurate measurements simplify crop growing and ensure improved growth.
2. Proper maintenance and storage of your probes ensure the most accurate measurements possible and maximise their lifespan. The probe surface is where the instrument measures the solution. If the probe is uncleaned and contaminated, measurements may be inaccurate. Like a car windscreen: if it is dirty, you will not be able to see the road! If the probe is contaminated, it cannot take accurate measurements.
3. Tip ... if the measured conductivity levels are too low, the probe needs cleaning.
4. The pH probe must be kept wet at all times for optimum performance and a long life!

1. Your pH meter is only as accurate as its probe is clean. Accurate measurements simplify crop growing and ensure improved growth.
2. Cleaning and correctly storing your pH probe ensure the most accurate measurements possible and maximise the probe’s life.
3. The probe surface is where the instrument measures the solution/soil. If the probe is unclean and contaminated, measurements may be inaccurate. Like a car windscreen, if it is dirty, you cannot see the road. If the probe is contaminated, it cannot measure the concentration of the solution/soil.
4. The pH probe must be kept wet at all times for optimum performance and a long life!

Bluelab pH Probe Storage Cap. It is essential to replace the storage cap on the tip of the pH probe immediately after use and while it is stored. "If it dries out, it dies!". Keep the tip of the pH probe wet by ensuring there is enough Bluelab pH Probe KCl Storage Solution to cover it.
