Mi151 is an advanced pH/Temp microprocessor-based bench meter, that can also measure with ORP electrodes, thanks to its capability to measure mV with a resolution up to 0.1 mV.
This meter 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.
Fast easy-to-read results with large duel level digital LCD readout.
Extreme accuracy to ±0.002 pH | +/- 1 mV OPR | +/- 0.4°C (+/-0.8°F).
Extended pH range (-2.00 pH to 20.00 pH / -2.000 to 20.000 pH).
Lightweight, sleek design with small benchtop footprint.
Simple easy-to-use logging and USB download functions, manual or on stability up to 1,000 logs.
Electrode diagnostics feature checks and displays the condition of the pH electrode.
Easy measurement: just place the electode and temperature probe in the sample, gently stir and wait for the reading to stabilize.
Simple push button, automatic up to 5 point calibration for increased accuracy.
Up to 7 Standard calibration solutions (1.68, 4.01, 6.86,7.01, 9.18, 10.01 and 12.45) and 2 custom choices.
Refillable, glass, double junction lab grade pH electrode for low maintenance and high performance with a screw on cap to ensure proper storage.
Built-in rechargeable battery with 8 hours battery life (battery included).
Selectable Auto-off feature.
Alphanumeric LCD display messages for friendly, intuitive information, warnings and error messages.
Internal clock date to keep track of different time-dependent functions (calibration, timestamp,calibration time out).
3 feet probe cables for extra flexibility when testing.
CLEANING AND MAINTENANCE
Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution. Also:
1. Inspect the electotrode for damage or scratches, if present replace the electrode.
2. Inspect the cable. The connection cable and insulation must be intact.
3. Connectors should be clean and dry.
4. Rinse off salt deposits with water or DI water.
The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO Plus pH meter accurate. Also, calibrate after cleaning or a long period of storage.
