-Working principle Biological process electrodes can be used repeatedly in high temperature and high pressure environments such as steam disinfection. DKK's electrodes for biological processes can also exert superior performance in this harsh environment. -Features: Strong glass film achieves 10 times the mechanical strength of the original ordinary glass film. And the use of gel-type reference solution, no need to replenish KCl solution. The reference electrode adopts a double-salt bridge structure with strong anti-pollution ability, and a complex resin capable of capturing silver ions to eliminate clogging of the liquid junction. In addition, considering the environmental factors, this series of electrodes use completely lead-free glass, solder and other materials
