Eutech pH Test

Q: What pH range and accuracy does the pHTestr30 give?

-1.0 to 15.0 pH at 0.01 pH resolution, with a stated accuracy of ±0.01 pH.

Q: How many calibration points, and which buffers?

Three points, with auto-buffer recognition for USA 4.01 / 7.00 / 10.01 or NIST 4.01 / 6.86 / 9.18.

Q: Is temperature compensation automatic?

Yes — ATC is built in, and the dual display shows temperature next to pH over 0 to 50 °C.

Q: Can I replace the electrode?

Yes — the pH sensor unscrews and is sold separately as PHSENSOR03DJ, so an aged electrode does not write off the tester.

Q: How long does a set of batteries last?

About 500 hours from four 1.5 V alkaline button cells, with auto power-off after 8.5 minutes to stretch it further.

Q: Is it waterproof enough for tank-side and pond-side work?

The housing is waterproof and dustproof; Eutech does not publish a formal IP rating for this model.

Q: What else do I need to run it?

pH 4.01, 7.00 and 10.01 buffer solution for calibration and pH electrode storage solution to keep the junction wet between uses.

A waterproof pH and temperature pen for aquaculture, hatchery and hydroponic water.

Product Information

Key Features

Wide pH range -1.0 to 15.0, resolution 0.01 pH, accuracy ±0.01 pH
Temperature 0 to 50 °C displayed alongside pH, resolution 0.1 °C, accuracy 0.5 °C
3-point calibration with auto-buffer recognition — USA (4.01 / 7.00 / 10.01) or NIST (4.01 / 6.86 / 9.18)
Automatic temperature compensation (ATC) so readings hold up as water temperature moves
Large dual-level LCD shows pH and temperature together, with self-diagnostics, hold function and auto power-off after 8.5 minutes
Waterproof and dustproof housing built for wet, dirty field work
Replaceable pH sensor (PHSENSOR03DJ) — refit rather than replace the whole tester
Four 1.5 V alkaline button cells give about 500 hours of use
Choosing your model: order the complete pHTestr30 tester if this is a new instrument, or the replacement sensor on its own if you already run a pHTestr30 and the electrode has aged out.
