YR01825 Benchtop pH / Ion Meter

Manufacturer: Kalstein

Certificacion europea

Product Description

Professional pH and ion meter, 2 to 5 points calibration, setup menu contains 20 options. The meter is suitable for measuring the pH, mV, ion concentration and water hardness.

pH Mode

• Professional 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.
