901P Portable pH/Conductivity Meter

Multiparameter portable pH/Conductivity meter contains 4 measurement modes, the meter is suitable for measuring the pH, mV, conductivity and TDS.

 pH Mode:
• Multiparameter portable pH/conductivity meter is equipped with a 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.

Conductivity/TDS Modes:
• 1 to 5 points calibration, automatically recognizes the conductivity standard solutions.
• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear
  and pure water compensation modes.

Other Features:
• Automatic Temperature Compensation ensures accurate readings 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-Read 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 for checking the electrode performance.
• Setup menu allows setting the 12 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.
