About this item

Automatic temperature compensation ensures accurate readings over the entire range.

Auto-read function senses and locks the measurement endpoint.

Calibration due alarm reminds the 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.

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.
