Product Description

Handheld pH Meter with Enhanced Design

Rugged high specification pH and ORP / Redox

HI 9124 and HI 9125 are rugged,
high specification portable meters.
Both measure pH but the HI 9125 offers
the additional advantage of being able to measure ORP.

  • Heavy-duty waterproof casing
  • Large clear LCD display
  • Extended pH and temperature given simultaniously
  • Memorises pH reading and recall
  • Battery % remaining on start up
  • User-friendly text and graphics support calibration procedure without constant reference to a manual
  • Automatic temperature compensation
  • Rubberised keyboard
  • Fully automatic buffer recognition
  • Automatic pH calibration with five memorised pH buffer values and buffer recognition to simplify calibration
  • User-selectable calibration time-out
  • Battery error prevention system (BEPS)
  • HI 7662 stainless steel temperature sensor included as standard
  • HI 1230B double junction pH electrode minimises junction contamination and enhances accuracy (supplied as standard)

For pH: select HI 9124
HI 9124 offers high specification pH testing in a strong portable casing

For pH & ORP: select HI 9125
HI 9125 measures pH plus ORP/Redox in one rugged, high specification meter using optional HI 3230B ORP/Redox electrode

HI 9124 and HI 9125 are each supplied with:

  • HI 1230B pH electrode
  • HI 7662 temperature probe
  • Starter pack of buffer solutions
  • 100 ml plastic beaker
  • Batteries and instructions
