pH-HR shown with M-11-Pt100 pH probe and pH-HR Plug Set


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 Pt100 temperature probe to allow temperature compensation of the pH reading. Many pH probes have a built in Pt100 temperature sensor for convenient connection.
The pH-HR logger also has an internal temperature sensor for convenient logging of ambient temperature if desired.

1 to 5 year battery life depending on usage as below, user replaceable. Data is retained in the event of battery failure. Battery Status Monitor in Omni7 / OmniLog Software.

  • Warning: When using the Average, Maximum or Minimum reading(s), the loggers reads the attached sensor(s) every second. This will reduce battery life.
  • Using the logger in temperatures below -5°C (23°F) will reduce battery life.
