| titleOfInvention | ORP (oxidation-reduction potential) measuring instrument calibration device and calibration method |
| abstract | The invention provides an ORP (oxidation-reduction potential) measuring instrument calibration device and a calibration method, wherein a pH meter verification instrument is configured to output a mV value to the ORP measuring instrument, and a high-resistance resistor R and a switch K are connected in series on an output circuit of the pH meter verification instrument connected with the ORP measuring instrument so as to detect an electric meter potential indication value error, electric meter potential repeatability, electric meter input current and electric meter input impedance of the ORP measuring instrument; two jars are configured for containing two different ORP standard solutions and are stored in a constant-temperature water tank, and the two jars are used for calibrating electrodes of an ORP measuring instrument by means of an oxidation-reduction depolarization automatic measuring instrument and one ORP standard solution; the ORP measuring instrument is calibrated by the device and the calibration method, the problem that results cannot be unified due to different expression modes under different standards is solved, and the tracking performance is good, accurate and reliable. |
