⚡ At a Glance
- • Accuracy: ±0.1 pH accuracy across a 0–14 pH range, with ±0.5°C temperature sensing
- • Best for: Hobbyists, brewers, aquarium keepers and field technicians needing repeatable readings
- • Not ideal for: Users who require laboratory-grade certified calibration records
Auto Temp Compensation keeps pH readings reliable between 0–50.0°C. Auto calibration with buffer recognition and stable-value signalling reduces user guesswork.
Consistent results in changing conditions – thanks to Auto Temperature Compensation (ATC)
Auto Temperature Compensation adjusts pH calculations according to measured temperature within the 0–50.0°C range. Temperature sensor reports to the meter so pH is corrected automatically rather than manually.
Consistent pH values when testing samples at different temperatures, reducing the need for manual correction and repeat tests.
Faster, more reliable setup – with Auto calibration and buffer recognition
Auto calibration recognises standard buffer solutions and confirms completed calibrations on-screen. The system flags successful calibration points so users know when the probe is ready.
Calibration takes less guesswork and less time, making routine checks quicker and more repeatable for daily use.
Field-ready convenience – with a complete kit and long battery life
The kit includes ready-to-use calibration solutions, AAA batteries, a lanyard and a portable carrying case. Power-efficient electronics allow up to 2000 hours of continuous operation on supplied batteries.
Immediate use out of the box and extended operation in the field or classroom without frequent battery changes.
