Standard BNC connector can connects many Ion selective Electrode.
2 to 5 points push-button calibration from low to high concentrations.
selectable multiple concentration units, including ppm, mg/L, mol/L.
Direct readout ion concentration simplifies measurement process.
mV measurement allows user to check performance of ion electrode.
Conductivity/TDS/Salinity Mode:
Up to 5-point push-button calibration allows user to uses customizedcalibration solutions.
Adjustable TDS factors, cell constants, temperature coefficients andnormalization temperature.
selectable linear or pure water compensation modes.
In salinity measurement modes, selectable practical salinity (PSU) orseawater measurement standard (ppt).  
Dissolved Oxygen Mode:
1 or 2 points auto-calibration (100% in saturated air or air-saturatedwater, 0% in zero oxygen solution).
Manual salinity and barometric pressure compensation.
selectable readout in ppm, mg/L or percentage saturation.
General Features:
Automatic Temperature Compensation  (ATC)  ensures highlyaccurate measurements over the entire range.
Calibration due reminder helps you to calibrate meter regularly.
Automatic endpoint function freezes stable measured values.
Help message as a operational guide to helps you understandhow to use meter.
Setup menu lets user customize the calibration points, stabilityconditions, date and time to meet  measurement requirements.
Expanded memory stores and recalls up to 500 readings.
Built-in real-time clock stamps stored data to meets GLP.
Stored data can be transferred into PC via USB communication interface.
