Benchtop pH/ORP/Ion Meter

Benchtop pH/ORP/Ion Meter Features: pH: 1. 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. Solution temperature coefficient compensates for the pure water samples and references the pH to 25°C ORP: 1. 1 point offset calibration allows adjusting the displayed value to a known standard 2. Relative and absolute millivolt modes ensure the reliable ORP measurements Ion Concentration: 1. 2 to 5 points calibration, including the 8 concentration points can be selected 2. Electrode management is capable of storing and recalling up to 3 electrode slopes 3. Automatic electrode diagnosis shows the calibration points and slopes 4. Selectable ion measurement methods (direct reading, known addition, known subtraction, sample addition, sample subtraction) and concentration units (ppm, mg/L, mol/L or mmol/L) Water Hardness: 1. 2 to 5 points calibration from low to high concentrations 2. Selectable measurement units (German degree, English degree, French degree, mmol/L and mg/L) are used for professional water hardness measurements General Features: 1. Automatic temperature compensation ensures accurate readings over the entire range 2. Auto-Read function senses and locks the measurement endpoint 3. Timed Interval Readings sends the measurement data to a PC or printer 4. Limit Alarm automatically alerts when reading exceeds the specified range 5. Calibration due alarm prompts user to calibrate the meter regularly 6. Password protection prevents the unauthorized calibration and settings 7. Expanded memory stores or recalls up to 1000 data sets 8. Reset function automatically resumes all settings back to the factory defaults Technical Parameters: Model PH-A120-CN PH-A120-UK PH-A130-CN PH-A130-UK PH-A131 PH Range -2.000~20.000pH • • — Resolution 0.001, 0.01, selectable • • — Accuracy ±0.002pH • • — Calibration Points 1 to 5 points • • — pH Buffer Options USA, NIST, DIN, 5 custom buffers • • — ORP(optional) mV Range ±2000.0mV • • • Relative mV Range ±2000.0mV • • — Resolution 0.1mV • • • Accuracy ±0.2mV • • • Calibration Points 1 point • • — Ion Range 0.001~30000 (depending on the range of ISE) — • • Resolution 0.001, 0.01, 0.1, 1 — • • Accuracy ±0.5% F.S.
