Features:
pH:
*Multiparameter water quality meter is equipped with a 6.5 inches backlit LCD display 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
*Automatic electrode diagnosis shows the pH slope and offset.
ORP:
*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:
*2 to 5 points calibration, including the 8 concentration points can be selected.
*Direct ion concentration readout simplifies the measurement process.
*Automatic electrode diagnosis shows the calibration points and slopes.
*Selectable concentration units (ppm, mg/L, mol/L, mmol/L) and ionic valency.
Conductivity/TDS/Salinity/Resistivity:
*1 to 5 points calibration with automatic recognition for conductivity standards.
*Selectable cell constant, reference temperature, TDS factor, linear and pure water compensations, seawater and practical salinity measurement modes.
*Automatic electrode diagnosis shows the calibration points and factors.
Dissolved Oxygen:
*1 or 2 points calibration using the air-saturated water or zero oxygen solution
*Salinity and barometric pressure compensations eliminate the measurement error
Other Features:
*Automatic temperature compensation ensures accurate readings over the entire range.
*Auto-Read function senses and locks the measurement endpoint.
*Calibration due alarm prompts user to calibrate the meter regularly.
*Setup menu allows setting the number of calibration points, resolution, stability criteria,temperature unit,
date and time, etc.
*Reset function automatically resumes all settings back to the factory defaults.
*Expanded memory stores or recalls up to 500 data sets.
*USB communication interface for data transfer and timed interval readings.
