Martini Mi151 pH / ORP / Temperature Laboratory Bench Meter.

This high performance economy microprocessor-based pH/ORP/Temp Bench meter is an ideal tool in schools, laboratories and production plants.

It is provided with a series of new diagnostic features which add an entirely new dimension to the measurement of pH, by allowing the user to dramatically improve the reliability of the measurement:

• Automatic Temperature Compensation (ATC) for good accuracy under fluctuating temperatures;
• Hold Function freezes reading for easy viewing;
• Easy to read large custom LCD;
• Stability Indicator prompts whenever reading stabilizes;
• 7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) for calibration;
• Messages on the LCD to make the calibration easy and accurate;
• User-selectable “calibration time out” to remind when a new calibration is necessary.

Mi151 can also measure with ORP electrodes, thanks to its capability to measure mV with a resolution up to 0.1 mV. For accurate measurements, use the electrode holder supplied with the meter.
