• Measures pH & Temp or PH, ORP & Temp (HI 9125N)
• Simple to Operate
• Ideal for Field Measurements

HI 9124 and HI 9125N are microprocessor-based pH meters in water proof casings. HI 9124 measures pH and temperature, and HI 9125N can also measure ORP in the mV range. Both meters are housed in rugged, water proof, ABS casings that are built to last. The Auto-Instruction feature guides the user step-by-step through the calibration process with graphic symbols. The automatic calibration procedure is simple and quick and can be performed at 1 or 2 points selected from 5 memorized buffers: pH 4.01, 6.86, 7.01, 9.18, 10.01. A stability indicator assures a correct calibration.

HI 9124 is supplied complete with HI 1230B pH electrode, HI 7669/2W temperature probe, pH 4 and pH 7 buffer sachets, 100 mL plastic beaker, batteries, rugged carrying case and instructions. HI 9125N is supplied complete with HI 1230B pH electrode, HI 7669/2W temperature probe, pH 4 and pH 7 buffer sachets, 100 mL plastic beaker, batteries, rugged carrying case and instructions.
