The HI981412 uses the HI10063 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector. The built in amplifier helps to reduce electrical noise from recirculation pumps to provide for a stable, reliable measurement. The pH glass used is ideal for low conductivity water and provides for fast response. The PVDF body of the probe has a 1/2” threaded fitting for insertion to an in-line "T" fitting or the flow cell. The backend part of the probe has 3/4" NPT threads for submersion/tank mounting. The probe body has a hex fitting for tightening snuggly with a wrench.
