Điện Cực pH Đầu Phẳng Cho Da Người Và Bề Mặt Với Đầu Nối BNC – Hanna Instruments HI1413B

The HI1413B is a glass body, single reference junction pH electrode made with low temperature glass and a BNC connector. This electrode has a unique open junction design in which there is a viscolene (hard gel) electrolyte layer that is free of silver chloride (AgCl) between the sample to be measured and the internal reference cell. The open junction design resists clogging and the probe’s flat tip makes it ideal for pH measurements on surfaces such as skin, leather, and paper.
