Q: Do I need to calibrate my tester? A: Regular calibration helps to maintain tester accuracy

Q: What is 3-point calibration? A: Single-point calibration only allows calibration at one chosen point, which should be near the pH range of your application. 3-point calibration allows calibration at 3 different points (pH 4, 7 and 10) to give you ±0.1 pH accuracy across the acid and alkali ranges. If your application requires pH measurements that vary greatly, you should use EcoTestr pH 2, which offers 3-point calibration.

Q: Do I need Automatic Temperature Compensation (ATC)? A: The necessity of ATC depends on your accuracy requirement. Sensor sensitivity to pH changes with temperature variation. With ATC, the tester automatically detects and compensates for such temperature variations.
