pH Controller with temperature sensor v2

This pH controller is for aquarists who run CO2 injection and want pH held at a set value instead of adjusting the gas by hand. It reads pH through a probe and uses that reading to control CO2 supply, keeping the water at a stable level such as 6.8 pH.

Why it matters

• The probe is calibrated automatically using pH 4 and pH 7 buffers, so the reading does not depend on manual setup each time.
• Measurement range is 0–14 pH with an accuracy of 0.1%, which gives fine resolution around the target value.
• The controller holds a setpoint within 3.5–10 pH, covering the range most CO2-supplemented setups operate in.
• The LED display shows pH to one decimal place, with water temperature shown below it.

What it works with

The controller is intended for planted freshwater aquariums where CO2 is dosed and pH is the value being regulated. It mounts on the tank rim, on the front of a cabinet, or inside a cabinet with the supplied screws, so it fits both open and enclosed aquarium stands. Tank volume is not specified in the product data.
