Measurement parameters
Product details
Functional characteristics of pH unit
Circular pH sensitive membrane, fully sensing the pH value of the liquid.
Calibration from 1 to 3 points, automatically identifying USA or NIST standard buffer solutions.
Automatic temperature compensation ensures accurate measurement across the entire range.
The settings menu allows customization of pH buffer standards, number of calibration points, temperature units, etc.
Functional characteristics of EC unit
Platinum conductive electrode provides accurate and reliable measurement results.
Calibration from 1 to 3 points, automatic identification of conductivity standard solution.
Automatic temperature compensation, correcting conductivity measurements and converting readings to reference temperature.
The settings menu allows customization of the number of calibration points, TDS coefficient, temperature units, etc.
Functional characteristics of DO unit
Equipped with a polarographic electrode.
1 or 2-point calibration, using air saturated water or zero oxygen solution.
Salinity and atmospheric pressure compensation eliminate measurement errors.
Automatic temperature compensation ensures accurate measurement across the entire range.
The settings menu allows customization of the number of calibration points, concentration units, temperature units, etc.
General functional features
Automatic endpoint locking, retaining stable readings for easy browsing and recording.
Automatic power shutdown effectively saves battery energy consumption.
Reset function, automatically restore the instrument to factory default settings.
