A130 Benchtop pH/Ion Meter
Professional laboratory pH/ion meter contains 5 ion concentration measurement methods and water hardness measurement mode, 1 to 5 points calibration, accuracy: 0.002pH.
pH Mode:
• Professional laboratory pH/ion meter is equipped with a 7 inch TFT display.
• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
• 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.
Ion Concentration Mode:
• 2 to 5 points calibration, including the 8 concentration points can be selected.
• Electrode management is capable of storing and recalling up to 3 electrode slopes.
• Selectable ion measurement methods (direct reading, known addition, known subtraction,
sample addition, sample subtraction) and concentration units (ppm, mg/L, mol/L, mmol/L).
Water Hardness Mode:
• 2 to 5 points calibration from low to high concentrations.
• Selectable measurement units (german degree, english degree, french degree, mmol/L
and mg/L) are used for professional water hardness measurements.
Other Features:
• Automatic temperature compensation ensures accurate readings over the entire range.
• 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, calibration points, slopes 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.
