Multiparameter portable pH meter contains 8 measurement modes, the meter is suitable for measuring the pH, ORP, ion, conductivity, TDS, salinity, resistivity and dissolved oxygen.
pH Mode:
? Multiparameter water quality meter is equipped with a 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 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.
? 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 Modes:
? 1 to 5 points calibration with automatic recognition for conductivity standards.
? Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear
and pure water compensations, seawater and practical salinity measurement modes.
Dissolved Oxygen Mode:
? 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.
? Auto-Power Off effectively conserves battery life.
? Setup menu allows setting the number of calibration points, 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 is easy to transfer data to PC.
? Multi-mode power scheme (batteries, power adapter and USB port) ensures that using the
meter smoothly.
