It includes a durable peristaltic tube for long-lasting performance and a protective cap for the pH probe to ensure accurate readings.

4.3 Operating Principle
The Davey Peristaltic pump adjusts its dosage in proportion to the demand. It will dose less if the displayed measure is near the set point. In normal operation, the AS Series pump will increase its ‘non operational’ time period proportional to the required dosage demand. That is why the device often has the pump off.
This is normal.
Adjust the pH slowly to preserve the natural quality of your water.
After 30 minutes without pressing the keys, the backlight turns off to save energy. A short press on
SET or CAL turns it on again.
