Grower Tip
- Rinse the probe with distilled or deionised water before and after every test.
- Begin calibration with pH 7.00, then add pH 4.00 or 10.01 points for the expected range.
- Keep the storage cap moist with 3M KCL; never store the probe in pure water.
- After a month unused, soak the probe in 3M KCL for 30 minutes before testing.
Features
The handheld meter measures solution pH and water temperature from one replaceable probe.
A lithium glass membrane sensor provides the listed ±0.01 pH measurement accuracy.
The interchangeable sensor extends the meter's service life without replacing the complete unit.
Included pH 4.00, 7.00 and 10.01 solutions support calibration across acidic, neutral and alkaline ranges.
Included 3M KCL maintains the glass electrode in suitable storage conditions between uses.
The meter carries an IP67 rating and includes a removable shield around the glass sensor.
-
1
Prepare the probe
Remove the cap, rinse the probe with distilled or deionised water and shake off excess moisture.
-
2
Calibrate from neutral
Calibrate with pH 7.00 first, then use pH 4.00 or 10.01 points suited to the expected range.
-
3
Rinse between solutions
Rinse the probe with distilled or deionised water between calibration buffers and before testing the sample.
-
4
Measure the sample
Place the probe in the solution, stir briefly, then hold it still until the display indicates a stable reading.
-
5
Review the result
Read the displayed pH and temperature, using the hold function when a stable result needs to be retained.
-
6
Clean and store
Rinse after testing and close the cap with 3M KCL solution to keep the electrode moist.
What solutions are included with the pH Meter PRO Kit?
The kit includes ready-to-use pH 4.00, 7.00 and 10.01 calibration solutions plus 3M KCL soaking solution. The buffers support calibration across common measurement ranges, while the KCL solution keeps the glass electrode properly conditioned during storage.
Which calibration point should I use first?
Always begin with the pH 7.00 point for the USA buffer series. Complete pH 4.00 or 10.01 calibration points afterward according to the range you expect to measure. Do not switch the meter off between points during a multi-point calibration.
How should the probe be stored?
Keep the probe cap moist using 3M KCL solution or pH 4.00 buffer for long-term storage. Never store the electrode in tap, reverse-osmosis, distilled or deionised water because pure water can damage the probe. Pure water is for rinsing only.
Can the entire meter be submerged?
No. Although the meter carries an IP67 rating, the manual says not to fully submerge the complete device. Immerse only the sensing end as required for measurement, keep the screw cap secure during use and reinstall the protective cap afterward.
When should the replaceable probe be changed?
Probe life is typically one to three years depending on use and maintenance. Consider replacement when readings become unusually slow, calibration repeatedly fails or the glass sensor is damaged. Install the new probe without twisting the pins, condition it in KCL and recalibrate before use.
Description
A digital water quality meter designed to measure water’s acidity, alkalinity, and temperature to help optimize its quality for gardening and water treatment applications.
The highly responsive sensor probe utilizes a lithium glass membrane to instantly determine pH readings with highly precise ±0.01 accuracy.
This pH pen tester for water features an IP-67 rating, specially sealed to withstand moisture and heat, as well as block out intrusive dust and sand. For further protection, the hydroponic pH meter is built with a sensor shield to safeguard your probe in between uses.
The included 4.00 pH, 7.00 pH, and 10.01 pH calibration solutions ensure consistently accurate measurements, while the 3M KCL solution supports proper storage conditions to help extend the lifespan of the pH and PPM meter.
REPLACEABLE PROBE
Each pH monitor sensor probe can be effortlessly replaced to support ongoing accuracy and speed with every reading. This extends your digital meter’s lifespan while simultaneously increasing savings by eliminating the need to purchase new lab pH meters. Simply install a replacement probe and continue monitoring your water quality without interruption.
APPLICATIONS
This fast-acting nutrient test alkalinity meter to help you determine how well your water uptakes nutrients. Fit for use as a pH meter for plants in horticultural settings like gardens, grow tents, greenhouses, and hydroponics systems. In addition, its application spans far beyond plant growing, capable of being a general pH level tester for water used in swimming pools, spas, aquarium fish tanks, and beverage homebrewing applications to help determine water safety.
