The MW150 MAX is an advanced microprocessor-based benchtop meter for measuring pH, ORP, and temperature in aqueous solutions. It is designed for students, lab technicians, and specialists who require fast and high-precision results.

This instrument features new diagnostic functions that provide a high level of reliability in pH measurements:

• Automatic 3-point calibration using 7 standard calibration buffers.

• Automatic or manual temperature compensation.

• Built-in rechargeable battery with 8 hours of autonomous operation.

• Auto-off function to preserve battery life.

• Alphanumeric LCD display for intuitive information, warnings, and error messages.

• Internal clock and date to track time-dependent functions (calibration timestamps).

• Dedicated GLP (Good Laboratory Practice) key.

Technical Specifications:

• Measurement Range: pH: -2.00 to 20.00; ORP: ±1000.0 mV / ±2000.0 mV; Temp: -20.0°C to 120.0°C (-4.0°F to 248.0°F).

• Resolution: 0.01 pH; 0.1 mV; 0.1°C / 0.1°F.
