What are the features of the Hanna Koi Pond pH Controller With Pump?

The Hanna Koi Pond pH Controller With Pump features an amplified pH/temperature probe that connects to the controller with a single waterproof Quick Connect DIN connector. Designed for use in low‐conductivity water, it provides fast, stable measurements and includes an integrated amplifier that reduces electrical interference from pumps and other equipment commonly found in recirculating systems. The PVDF body of the probe includes a ½" threaded fitting for insertion into a flow line or T‐fitting, and ¾" NPT threads for submersion applications. A hex‐shaped section on the body allows for easy, secure tightening during installation. This dual‐parameter probe is ideal for reliable performance in demanding horticultural applications.
