Mi106 pH / ORP / Temperature Professional Portable Meter

Extended Range pH/ORP/Temperature Meter The Mi106 multi parameter portable meter is ideal for field measurements. The included combined pH/ORP electrode has a built-in temperature sensor and amplifier to prevent electrical interference. The large display shows readings in an extended range from -2.00 to 16.00 pH or ±2000 mV and simultaneously shows temperature from -5.0 to 105.0°C or 23 to 221°F.

The Mi106 has a stability indicator and hold feature that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. When switched ON it performs a self-check and displays the percentage of the remaining battery level to assure proper working condition. Calibration is performed automatically at 1 or 2 points using standard or NIST buffers.
