904P Portable Conductivity/Dissolved Oxygen Meter
Multiparameter portable Conductivity/Dissolved Oxygen meter contains 5 measurement modes, the meter is suitable for measuring the conductivity, TDS, salinity, resistivity and DO.
Conductivity/TDS/Salinity/Resistivity Modes:
• Multiparameter portable conductivity/dissolved oxygen meter is equipped with a backlit LCD.
• 1 to 5 points push-button calibration, automatically recognizes the calibration solutions.
• 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 ensure the reliable DO measurements.
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.
• Calibration report provides the details for checking the electrode performance.
• Battery indicator shows the remaining battery capacity.
• Auto-Power Off effectively conserves battery life.
• Setup menu allows setting the 13 parameters, including the number of calibration points,
stability criteria, temperature unit, date and time, 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.
