The new Hetai PH meter instrument has been shortened by 47mm in depth

The new Hetai PH meter instrument has been shortened by 47mm in depth, making it easier to install the electrical box and reducing the installation space in the box, thus lowering the overall cost of the electrical cabinet. Please read the instructions carefully before using the HeTai PH-101N. In order to make the measurement more accurate, pH instruments need to calibrate the electrodes regularly. The shelf life of glass pH 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. The pH electrode that has just been used or has been out of use for a long time must be soaked in a 3mol/L solution for 24 hours before use.

The electrode used in the analysis of the Hetai PH-101N instrument comes from BJC company in the United States. It is currently one of the industrial pH electrodes with a wide variety and good quality in Europe and America, and can be applied to 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 pH electrode.

Hetai PH-101NMaintenance and precautions:

1. The input terminal (measuring electrode socket) of PH-101N instrument must be kept dry and clean to prevent dust and water vapor from entering.2Avoid immersing the electrode in protein solution and acidic fluoride solution for a long time, 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 ()3～5Second, then rinse with distilled water and use again0.1mol/LSoak in hydrochloric acid to renew the electrode.4．To calibrate the electrodes more frequently and clean them with distilled water for measurement.
