The new Hetai ORP control instrument ORP-101N has a depth reduction of 47mm, making installation of the electrical box more convenient, reducing the installation space in the electrical box, and lowering the overall cost of the electrical cabinet. Please read the instructions carefully before using the Heptech ORP-101N. In order to make the measurement more accurate, the instrument needs to calibrate the electrodes regularly. The shelf life of glass ORP electrodes is one year. After one year from the factory, their performance will be affected regardless of whether they are used or not, and they should be replaced in a timely manner.ORP electrodes used or ORP that has been discontinued for a long timeThe electrode must be used before use3mol/L kclSoak in solution24h。

The electrode used in the Hetai ORP-101N water quality analysis instrument comes from BJC company in the United States. It is currently the most diverse and high-quality industrial ORP electrode in Europe and America, and can be used in various occasions such as wastewater tanks and fermentation tanks. The controller produced by our company is a high impedance input type, which can be applied to any brand of industrial ORP electrode.

Hetai ORP-101NMaintenance and precautions:

1. The input terminal (measuring electrode socket) of ORP-101N instrument must be kept dry and clean to prevent dust and water vapor from entering.2Avoid long-term immersion of ORP electrodes in protein solutions and acidic fluoride solutions, and avoid contact with organic silicone oil.3After long-term use of the electrode, if the slope slightly decreases, the lower end of the electrode can be soaked in water4％HFIn solution (hydrofluoric acid)3～5Second, then rinse with distilled water and use again0.1mol/LSoak in hydrochloric acid to renew the electrode.4．To make the measurement more accurate, it is necessary to calibrate the ORP electrode regularly and clean it with distilled water.
