Care and Use of Bluelab Soil pH Probes
“Thank you for choosing a Bluelab soil pH probe.”
The information below will ensure this product will perform to its best.
Please read the instructions and keep them in a safe place to refer back to when required.
Glass bulb pH probes are FRAGILE. Treated with care they will give a long service life. Do not exert a sideways force on
the electrode as this may break the glass stem. Do not knock the probe against anything as it will damage the glassware.
A sudden temperature change can also break the glassware - do not plunge a cold pH probe into a hot liquid. pH Probe
Lead Care: Do not kink the lead or bend sharply. The lead on the probe cannot be lengthened. It is safe for the probe to
be submerged in fluid but DO NOT submerge the BNC fitting.
If it is to measure proteins or suspended solids, the probe must be soaked in 1% Pepsin for 15 minutes after use.
Preparation for Use: pH probe glassware is designed to stay wet. To remove the wetting cap, grasp the probe near the
wetting cap and gently slide the cap off. The glassware needs to be kept wet for optimal performance. For long term
storage, place a small amount of clean water (not distilled water) or pH 4 solution into the wetting cap and place over the
probe tip. It is recommended by Bluelab that new probes should be stood upright in a container of fresh water or pH 4
solution for 1 hour before use. pH probes that have been allowed to dry out need to be soaked in water for 24 hours
before use (re-hydration). This is necessary to ensure the probe works reliably.
Cleaning Method for Bluelab Soil pH Probes - Cleaning of the glassware is of critical importance!
1. Rinse soil pH probe tip under fresh running water.
2. Fill a small container with clean water and add a small
amount of mild detergent (dishwashing liquid).
3. Place the probe into the container and slowly stir it
through the liquid. Ensure that you do not ’knock’ the
probe on the side of the container as this may cause
damage to the probe. Rinse well under fresh running
water to remove all traces of detergent.
4. If the probe tip requires removal of heavy contamination
(nutrient salt build up or algae), gently brush around the
glassware with a few drops of mild detergent
(dishwashing liquid) and a soft toothbrush paying
attention to the area where the conductive wick comes
out beside the glassware. DO NOT pull out or touch the
wick. Rinse well under fresh running water to remove
all traces of detergent.
5. Recalibrate the meter by following the instructions on
the back of your Bluelab Meter.
