Product Description

A131 Laboratory Benchtop Professional ORP/ Ion/ Water Hardness Test Meter
MEASUREMENT PARAMETERS
A131 meter: Ion Concentration, Water Hardness, mV, Temperature

FEATURES
ORP:
1 point offset calibration allows adjusting the displayed value to a known standard.
Relative and absolute millivolt modes provide the reliable ORP measurements.

ION:
Selectable ion measurement methods, including the direct reading, known addition, known
subtraction, sample addition and sample subtraction.
Selectable concentration units, including the ppm, mg/L, mol/L and mmol/L.
2 to 5 points calibration, providing the 8 concentration points can be selected.
Automatically recognizes the ion selective electrodes, does not need to specify type of ion.
Electrode management is capable of storing the 3 slopes and recalling the calibration data
of each electrode.
Calibration report provides the details of the calibration standard and slope.

WATER HARDNESS:
2 to 5 points calibration from low to high concentrations.
Selectable measurement units ( German degree, English degree, French degree, mg/L and
mmol/L) are used for professional water hardness measurements

GENERAL:
Calibration Due Reminder prompts user to calibrate the meter regularly.
Stability indicator shows when a measurement is recognized as stable.
Auto-Read feature senses and locks the measurement endpoint.
Interval Readings automatically send the measurement data to the computer or printer.
Password protection prevents the unauthorized calibration and settings.
Expanded memory stores and recalls up to 1000 data sets.
Stored readings can be transferred into the computer by USB communication interface.
Reset feature automatically resumes all settings back to factory default options.

METER INCLUDES
