A120 Laboratory pH Meter

High-precision laboratory pH meter with mV and relative mV measurement modes, 1 to 5 points calibration, 1000 sets of data storage, setup menu contains 15 options, accuracy: 0.002 pH.

pH Mode:
• High-precision laboratory pH meter is equipped with a 7 inch TFT display.
• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
• Automatic temperature compensation ensures accurate readings over the entire range.
• Solution temperature coefficient compensates for pure water measurements and references
the pH to 25°C.

ORP Mode:
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes ensure the reliable ORP measurements.

Other Features:
• Auto-read function senses and locks the measurement endpoint.
• Timed interval readings send measurement data to a PC or printer.
• Limit alarm automatically alerts when measurements exceed the specified range.
• Calibration due alarm reminds user to calibrate the meter regularly.
• Calibration log shows the date, time, calibration points, offset and pH slope.
• Password protection prevents unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
