Quick and Easy pH Measurements

• Clear LCD displays pH and temperature, or mV and temperature readings at the same time.
• Convenient calibration with automatic buffer recognition of US and
• European buffer sets. 1, 2, or 3 point calibration. Calibration data is stored in memory and is ready for use on power up.
• 40 Memory location for data storage (6230M and 6231M only).
• Readings are automatically compensated for temperature (ATC).
• Meter automatically switches into manual compensation when temperature probe is not present.
• Automatic lock mode and end point sensing are available to lock in stable readings.
• Intuitive operation with membrane keypad with tactile and audio feedback.
• Inclined back provides ideal viewing angle for benchtop use.

Carefree Maintenance

• Indicates when to change electrode for accurate readings.
• Watertight case is splash resistant and made with durable plastic intended for rugged use. Protective covers for connectors are included.
• Electrode holder neatly stores the electrode when not in use.

Standard Inputs and Outputs

• RS-232 computer interface (6230M and 6230N only) with software.
• BNC connector for pH/reference pH and mV.
• 8 pin DIN connector for 10k thermistor.
• Separate pin plug connector for reference pH.
• AC adaptor or battery power.
