pH Meters
A120 Laboratory pH Meter
High-precision laboratory pH meter with mV and relative mV measurement modes, 1 to 5 points calibration, setup menu contains 15 options, accuracy 0.002 pH.
Features:
pH
• 7-inch TFT display clearly shows measurement values, parameters and operation guidance.
• 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
• 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 measurement sends data to memory or a 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.
• USB communication interface enables easy data transfer to a PC.
• DAS software is capable of receiving data, recording measurements at specified intervals,
exporting data to Excel.
