Conductivity/TDS/Salinity/Resistivity Modes:

• Portable multiparameter water quality meter is equipped with a backlit LCD display.

• 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 errors.

Other Features:

• Automatic temperature compensation ensures accurate readings over the entire range.

• Auto-read function senses and locks the measurement endpoint.

• Auto-power off effectively conserves battery life.

• 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 a PC.

• Multi-mode power scheme (batteries, power adapter, USB port) ensures the smooth operation of the meter.
