I. use:
The modified electrode is composed of an indicator electrode platinum and a silver chloride reference electrode. The utility model is used for detecting the oxidation-reduction potential of the circuit board and the waste water treatment with a temperature of 5-70 DEG C, and the measuring range is -2000mV to 2000mV.
Two, the main technical parameters:
1, electrode potential: 245-270mV (15-30 degrees Celsius)
2. Electrode reference electrode internal resistance: 10KOmega
3. Stability of electrode:+ 8mV/24 hours
4. Electrode indicating electrode: good conduction
Three, use, maintenance and attention:
1 when the electrode is being measured, the test section of the electrode must be immersed simultaneously with the reference liquid junction.
2, the electrode standard solution - hydroquinone hydroquinone saturated solution preservation time is 48 hours. (attached: the configuration of the saturated solution of hydroquinone hydroquinone in which pH4.00 is added into the buffer solution to make it saturated)
3, the platinum electrode if stained with oil, you can use absorbent cotton dipped acetone or alcohol gently scrub clean, if stained with insoluble inorganic substances, you can use 30-50% hydrochloric acid scrub.
