Product Details
AUSTRALIAN SCIENTIFIC pH 10.0 Calibration Solution 500ml is a high-range buffer designed for calibrating pH meters when measuring alkaline solutions. It is commonly used as part of 2-point or 3-point calibration to ensure accurate readings across the full pH scale.
AUSTRALIAN SCIENTIFIC calibration fluids are the official buffers used with APERA INSTRUMENTS water control tools, including the PH60 and PC60 pocket pH testers.
Standardised at 25°C and colour-coded for easy recognition, these buffers are electrometrically checked against standard primary buffer solutions in accordance with NIST using traceable reagents.
This buffer is ideal when calibrating meters used to test hydroponic nutrient solutions and reservoir stability, ensuring reliable measurement in alkaline ranges.

pH meters require regular calibration using known reference solutions. The pH 10.0 buffer is used for high-range calibration, helping ensure the meter accurately measures solutions across the full pH spectrum from acidic to alkaline.
This is particularly useful when testing hydroponic nutrient reservoirs, where stable pH levels are critical for plant nutrient availability.
Rinse the Electrode
Rinse the probe with distilled or deionised water to prevent contamination.
Prepare the Buffer
Pour a small amount of AUSTRALIAN SCIENTIFIC pH 10.0 Calibration Solution into a clean, dry container. Never place the probe directly into the bottle.
Immerse the Probe
Insert the electrode into the buffer solution and gently stir to remove air bubbles.
Allow Reading to Stabilise
Wait for the meter reading to stabilise before confirming the calibration value.
Set the Calibration Point
Follow your meter’s instructions to set the calibration to pH 10.0.
Discard Used Solution
Always discard used buffer solution and never return it to the bottle.
🌡️ Standardised at 25°C for accurate calibration
🧴 Keep the bottle tightly sealed when not in use
🌑 Store in a cool, dark place
🚫 Never reuse calibration solution to prevent contamination
