±0.1 pH unit when measuring within 10 °C of the calibration temperature, widening to ±0.2 unit within 20 °C — recalibrate at pond temperature for the tighter figure.

YSI pH10A Pen Tester

Q: How many calibration points does the pH10A use?

1, 2 or 3 points, with automatic recognition of USA buffers 4.01, 7.00 and 10.01 or NIST buffers 4.01, 6.86 and 9.18.

Q: Is temperature compensation automatic?

Yes — automatic temperature compensation runs across the full 0.0 to 100.0 °C measuring range.

Q: Is the electrode replaceable, or is this a throwaway pen?

It is replaceable — fit a new single-junction (606110) or double-junction (605116) electrode when the old one wears out and keep the meter.

Q: Which electrode should I choose?

Single-junction for clean fresh water and general aquaculture; double-junction where sulfides, proteins or high salt would poison a single-junction reference.

Q: Can I use it pond-side in the rain?

Yes — the housing is IP67 waterproof and four LR44 cells give more than 200 hours of use.

Q: What do I need to keep it working?

pH 4.01, 7.00 and 10.01 buffer for calibration and pH electrode storage solution — never store the electrode dry or in deionised water.

A pocket pH and temperature pen for spot checks in aquaculture, aquaponics and hatcheries.

Temperature 0.0 to 100.0 °C, resolution 0.1 °C, accuracy ±0.3 °C
1-, 2- or 3-point calibration with automatic buffer recognition — USA (4.01 / 7.00 / 10.01) or NIST (4.01 / 6.86 / 9.18)
Automatic temperature compensation across the full 0.0 to 100.0 °C range
User-replaceable single-junction (606110) or double-junction (605116) electrode — the pen is reusable, not disposable
IP67 waterproof housing, one-handed operation and a graphic display with on-screen prompts
Four LR44 alkaline cells give over 200 hours; 50 data-set memory with date and time stamp
Choosing your model: the pH10A is a single meter, so the choice is the electrode — single-junction for clean fresh water and general aquaculture, double-junction where the sample carries sulfides, proteins or heavy salt (seawater, purge and processing water) and would otherwise poison a single-junction reference.
