pH Meter: HI 9025
*Product Manual Below*
Remember to purchase the pH standard solutions to calibrate this instrument. We recommend you choose both the 4.01 and the 7.01 solutions.
Waterproof Field pH Meters
- Measures pH & Temp or PH, ORP & Temp (HI 9025)
- Simple to Operate
- Ideal for Field Measurements
HI 9025 are microprocessor- based pH meters in waterproof casings. HI 9025 can also measure ORP in the mV range. Both meters are housed in rugged, waterproof, 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 9025 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.
