DESCRIPTION
DESCRIPTION
Measurement Parameters
pH, mV, relative mV, temperature
pH
• 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
• 1 point offset calibration allows adjusting the displayed value to a known standard
• Relative and absolute millivolt modes ensure the reliable ORP measurements General Features
• Auto-Read function senses and locks the measurement endpoint
• Auto-Power Off effectively conserves battery life
• Setup menu allows to set the pH buffer set, number of calibration points, resolution, stability criteria, temperature unit, 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
• Multi-mode powerscheme (batteries, power adapter and USB port) ensures that using
• USB communication interface is easy to transfer data to PC
