HI8014 is a rugged, handheld pH/ORP meter specifically designed with ease of use in mind. This affordable meter is ideal for education and field applications.
  • Manual Temperature Compensation
  • Two-point Calibration
  • Low Battery Indicator


HI8014 performs pH measurements with manual temperature compensation. HI8014 also performs ORP measurements using the mV range and optional ORP electrode (HI3131B). Two-point calibration can be performed with trimmers on the front panel. Temperature is manually compensated by using the trimmer. This rugged, manual pH/ORP meter is perfect for teaching students the fundamentals of pH and ORP measurement.
