Product Description
Professional portable pH meter with relative mV measurement mode, 1 to 5 points calibration, setup menu contains 9 options, accuracy: 0.002pH.
pH Mode:
• Professional portable pH meter is equipped with a backlit LCD display.
• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
• Automatic electrode diagnosis shows the pH slope and offset.
• 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 ensure the reliable ORP measurements.
• Auto-Read function senses and locks the measurement endpoint.
• Auto-Power Off effectively conserves battery life.
• Setup menu allows setting the pH buffer group, number of calibration points, resolution,stability criteria, date and time, etc.
• Reset function automatically resumes all settings back to the factory defaults.
• Expanded memory stores or recalls up to 500 data sets.
• USB communication interface is easy to transfer data to PC.
• Multi-mode power scheme (batteries, power adapter and USB port) ensures that using the meter smoothly.
