pH Meters
A120 Benchtop pH Meter
Professional benchtop pH meter, 7 inch TFT display, stores up to 1000 data sets, setup menu contains 17 options, accuracy: 0.002pH.
pH Mode:
• Professional benchtop 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 the pure water samples 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 sends the measurement data to a PC or printer.
• Limit Alarm automatically alerts when reading exceeds the specified range.
• Calibration due alarm prompts user to calibrate the meter regularly.
• Calibration report shows the date, time, pH slope and offset.
• Password protection prevents the unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
• Reset function automatically resumes all settings back to the factory defaults.
