Overview
YUEFENG PHS-3C laboratory acidity meter is a laboratory instrument with LCD display function, which can measure ph value and mV (ORP) parameters. Its pH Measurement range is 0~ 14.0pH, mV Measurement range is -1999~ 1999mV.
Features
1. Two parameters of measurement ph value and mV (ORP)
2. pH Measurement range is 0~ 14.0pH, resolution is 0.01pH
3.mV Measurement range of -1999~ 1999mV, resolution of 1mV
4. Measurement range is 0.0~ 60.0 ℃
5. Adopt LCD display
6. Support two-point calibration and automatic identification of 3 standard buffer solutions (4.00pH, 6.86pH, 9.18pH)
7. Instrument level is 0.01, with High Accuracy measurement capability
Principle
The acidity meter detects the concentration of hydrogen ions in the solution by Electrode and converts it into a pH value display; at the same time, it can measure the Oxidation-reduction potential of the solution, expressed in mV value. The instrument adopts a high input Impedance design (≥ 1 × 10 ^ 12 Ω) to ensure measurement accuracy.
Standards
Instrument level: 0.01 level
Steps
1. Two-point calibration
2. The instrument automatically recognizes the buffer solution (4.00pH, 6.86pH, 9.18pH)
3. Control the temperature of the tested solution within the range of 5 to 60 ° C
4. Start measurement of ph value or mV value
Notice
• The temperature of the tested solution should be within the range of 5~ 60 ° C
• Instrument Stability (0.01pH +/- 1 word)/3h
• pH intrinsic error is +/- 0.01pH +/- 1 word
• mV Measurement accuracy of +/- 0.1% F.S
