Portable pH Conductivity TDS Salinity Meter
High-performance multiparameter water quality meter contains the 6 measurement modes. The meter is suitable for measuring the pH, ORP, conductivity, TDS, salinity and resistivity of the samples.
pH Mode:
• Portable multiparameter water quality meter is equipped with a large backlit LCD display.
• 1 to 5 points push-button calibration with auto-buffer recognition.
• Selectable pH buffer group (USA/NIST/DIN) or using the custom calibration solutions.
• Automatic electrode diagnosis with pH slope and offset display.
ORP Mode:
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes provide the reliable ORP measurements.
Conductivity/TDS/Salinity/Resistivity Modes:
• 1 to 5 points calibration, automatically recognizes the conductivity standard solutions.
• Selectable cell constant (0.1/1/10), reference temperature (20°C/25°C), TDS factor, linear
and pure water compensations, seawater and practical salinity measurement modes.
Other Features:
• Automatic Temperature Compensation provides accurate reading over the entire range.
• Calibration Due Alarm prompts user to calibrate the meter regularly.
• Stability indicator shows when a measurement is recognized as stable.
• Auto-Hold feature senses and locks the measurement endpoint.
• Battery indicator shows the remaining battery capacity.
• Auto-Power Off effectively conserves battery life.
• Calibration report provides the details of the calibration standard and electrode slope.
• Setup menu allows setting the 12 parameters, including the number of calibration points,
stability criteria, temperature unit, etc.
• Reset feature automatically resumes all settings back to factory default options.
• Expanded memory stores and recalls up to 500 data sets.
• Stored readings can be transferred into the computer by USB communication interface.
• Multi-mode power scheme (batteries, power adapter and USB port) ensures that use the
meter smoothly.
