About this item:

Multiparameter water quality meter contains 6 measurement modes, suitable for measuring pH, ORP, conductivity, TDS, salinity and resistivity.

Automatic temperature compensation ensures accurate readings over the entire range.

Calibration due alarm reminds the user to calibrate the meter regularly.

Auto-read function senses and locks the measurement endpoint.

Setup menu allows setting the number of calibration points, stability criteria, temperature unit, date and time, etc.

pH Mode:

Portable 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 zero 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.

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.

Other Features:

Automatic temperature compensation ensures accurate readings over the entire range.

Auto-read function senses and locks the measurement endpoint.

Calibration due alarm reminds 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.
