Description
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.
Other Features:
- 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.
