Description
NOTE: It does not include triple AAA batteries due to air safety regulations.
The multi-parameter portable pH meter contains 8 measurement modes, the meter is suitable for measuring pH, ORP, ion concentration, conductivity, total dissolved solids (TDS), salinity, resistivity and dissolved oxygen.
PH mode
- The multi-parameter water quality meter is equipped with a backlit LCD display.
- 1 to 5 point calibration with automatic recognition for USA, NIST and DIN buffers.
- Automatic electrode diagnostics shows slope and pH offset.
ORP mode
- 1-point offset calibration allows the displayed value to be adjusted to a known standard.
- Relative and absolute millivolt modes ensure reliable ORP measurements.
- 2 to 5 calibration points can be selected, including the 8 concentration points.
- Direct reading of ion concentration simplifies the measurement process.
- Automatic Electrode Diagnostics displays calibration points and slopes.
- Selectable concentration units (ppm, mg / L, mol / L, mmol / L) and ionic valence.
Conductivity / TDS / Salinity / Resistivity Modes
- 1 to 5 point calibration with automatic recognition of conductivity standards.
- Selectable cell constant (K = 0.1 / 1/10), reference temperature (20/25 ° C), TDS factor, linear and pure water offsets, seawater and practical salinity measurement modes.
Dissolved oxygen mode
- 1 or 2 point calibration using air saturated water or zero oxygen solution.
- Salinity and barometric pressure compensations eliminate measurement error.
- Automatic temperature compensation ensures accurate readings throughout the range.
- The auto-read function detects and locks the end point of the measurement.
- Calibration Overdue alarm prompts the user to calibrate the meter regularly.
- Auto power off effectively conserves battery life.
- The configuration menu allows you to configure the number of calibration points, stability criteria, temperature unit, date and time, etc.
- The reset function automatically resumes all settings to the factory default values.
- Extended memory stores or recalls up to 500 sets of data.
- USB communication interface is easy to transfer data to PC.
- The multimode power scheme (batteries, power adapter and USB port) ensures that the meter is used smoothly.
