HANNA pH electrodes are suitable for different application environments and measurement needs. The electrodes are mainly made of glass, with a measuring range from 0 to 14 pH and a temperature range from 0 °C to 100 °C. Depending on the application requirements, the electrodes are designed with single or double dialysis wells to improve the accuracy and stability of the measurement. The electrode is filled with KCl 3.5M or Viscolene solution, which is resistant to pressure and is suitable for applications ranging from standard laboratory use to high-temperature and high-pressure environments. The electrode models in the table include immersion type, flat type, and high temperature and high pressure type, which are suitable for fields such as textile dyeing and finishing, strong acid and alkali solutions, high temperature, high pressure, nuclear waste pipeline detection, etc.
Refillable pH electrode with sidearm construction and BNC connector
HI1135B is a vitreous, refillable, double-junction pH electrode with BNC connectors. The electrode has a double ceramic junction at the outer junction and the pH sensing part is made of high-temperature glass. HI1135B also features a glass sidearm construction that allows for faster flow rates. This design consideration is ideal for applications that require continuous pH monitoring.
