Product Description Portable ORP PH Meter Product DescriptionIntroduction:The Portable pH Meter is a high-precision analytical instrument designed for accurate measurement of pH and oxidation-reduction potential(ORP) in various liquid solutions. Measurement Parameters:1. PH-220: pH, mV, temperature.2. PH-221: pH, mV, relative mV, temperature.PH-220 Features:1. 1 to 3 points calibration with automatic recognition for USA and NIST buffers.2. Automatic electrode diagnosis helps user decide whether to replace the pH electrode.3. Automatic temperature compensation ensures accurate readings over the entire range.4. Auto-Read function senses and locks the measurement endpoint.5. Setup menu allows setting the pH buffer set, number of calibration points, temperatureunit, auto-power off, etc.6. Reset function automatically resumes all settings back to the factory defaults.7. Expanded memory stores or recalls up to 100 data sets.8. USB communication interface for data transfer or connecting a power adapter to meter. PH-221 Features:PH1. 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.2. Automatic electrode diagnosis shows the pH slope and offset.3. Automatic temperature compensation ensures accurate readings over the entire range.4. Calibration due alarm prompts user to calibrate the meter regularly.ORP1. 1 point offset calibration allows adjusting the displayed value to a known standard.2. Relative and absolute millivolt modes ensure the reliable ORP measurements.General Features:1. Auto-Read function senses and locks the measurement endpoint.2. Auto-Power Off effectively conserves battery life.3. Setup menu allows setting the pH buffer set, number of calibration points, resolution, stability criteria, temperature unit, date and time, etc.4. Reset function automatically resumes all settings back to the factory defaults.5. Expanded memory stores or recalls up to 500 data sets.6. USB communication interface is easy to transfer data to PC.7. Multi-mode power scheme(batteries, power adapter and USB port) ensures that using the meter smoothly.Accessories:1. PH electrode2.
