Tadeto Soil pH Tester Digital Meter with Thermometer & Alloy Protective Cap — High Accuracy, 3-Point Calibration

The Tadeto Soil pH Tester is a portable, high-accuracy digital meter that measures pH and temperature in soil, water, food and solutions and includes three-point calibration supplies and a durable alloy protective cap.

Whether you maintain a backyard garden, manage crops, test aquarium water, or verify food and solution acidity, this handheld pH meter from Tadeto delivers precise readings with a clear LCD and useful functions designed for field and kitchen work. Built for versatility, it supports three-point calibration for better accuracy across acidic, neutral and alkaline ranges, shows temperature in real time, and includes a protective alloy cap to extend probe life.

How accurate is the Tadeto meter for garden and soil testing?

The meter uses a three-point calibration method (pH 4.01, 7.0 and 10.01) to tighten accuracy across the full pH range, making it suitable for soil fertility checks and general horticulture decisions. The instrument also alerts users to extreme readings with a red backlight when values fall below 3.5 or above 12.

• Three-point calibration for acidic, neutral and alkaline accuracy
• Clear LCD with backlight for low-light reading
• Alarm backlight highlights pH <3.5 or >12
• Real-time temperature display to contextualize pH results

Can I use this meter for water, food and solution testing?

Yes — the Tadeto meter is designed to test a variety of media, including freshwater, nutrient solutions, and liquid food samples, in addition to soil. Its probe supports liquid immersion and the device provides a stable reading once calibrated properly for the sample type.

• Suitable for garden soil, hydroponic solutions, aquariums and food liquids
• Calibration with supplied buffer powders ensures cross-media reliability
• Data hold function captures unstable readings for easier recording
• Compact, portable design for field, kitchen or lab bench use

What features protect the probe and prolong service life?

The meter includes a hard conical zinc-alloy protective cap that shields the electrode from damage when measuring firmer materials and during transport. After testing, adding a small amount of potassium chloride solution into the cap helps keep the electrode’s active surface hydrated and ready for consistent readings.

• Zinc-alloy protective cap secures the probe from impacts
• Conical tip design helps with firmer or compacted soil samples
• Simple post-use maintenance: potassium chloride in the cap preserves electrode activity
• Robust build for routine outdoor and indoor handling

How easy is it to calibrate and operate the Tadeto pH kit?

Calibration follows a straightforward three-point process using buffer solutions at pH 4.01, 7.0 and 10.01; the meter’s menu and display make the procedure clear. Basic operation is intuitive: power on, rinse probe, insert into sample, wait for stabilization, and use data-hold or alarm features as needed.

• Three-buffer calibration included for dependable baseline accuracy
• LCD backlight and clear digits speed reading outdoors or at dusk
• Data-hold makes logging results simple; temperature shown alongside pH
• Manufacturer support available if you have calibration or usage questions

Who this product is for: gardeners, small-scale farmers, hydroponic growers, aquarium hobbyists, food professionals and technicians who need a compact, multi-use pH tester with reliable calibration and probe protection. If you require a portable instrument that balances field durability with lab-style three-point calibration and temperature readout, the Tadeto Soil pH Tester is built to deliver practical, repeatable measurements across soil, water, food and solution testing tasks.
