Professional laboratory pH/ion meter contains 5 ion concentration measurement methods and water hardness measurement mode, 1 to 5 points calibration, accuracy: 0.002 pH.
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 log shows the date, time, calibration points, offset and slopes.
? 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.
