The pH-HR is a small three channel high resolution (12 bit) pH and Temperature data logger housed in a rugged 304 stainless steel case. The logger connects to an external pH probe and also has the option of connecting to an external RTD Pt100 temperature probe to allow temperature compensation of the pH reading. Many pH probes have a built in RTD Pt100 temperature sensor for convenient connection.
The pH-HR logger also has an internal temperature sensor for convenient logging of ambient temperature if desired. Logging can be configured to: start on time, immediate start, stop when full, loop around (overwrite oldest data).
A DLC3USB [USB] download cable (2m) is required to connect the pH-HR to a computer.
