Product Description
220 Portable pH Meter
You can use it to test liquid food, such as milk.
Features
pH Mode:
• Professional portable pH 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.
• Automatic Temperature Compensation ensures accurate readings over the entire range.
• Calibration Due Alarm prompts user to calibrate the meter regularly.
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.
Other Features:
• 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.
• Setup menu allows setting the 9 parameters, including the number of calibration points,
resolution, stability criteria, 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 or USB port) ensures that use the
meter smoothly.
