หัววัด pH Electrode จาก Hanna Instrument รุ่น HI1093B ออกแบบมาให้ปลายหัววัดมีขนาดเล็ก เหมาะสำหรับใช้วัดค่า pH ใน NMR Tube (Nuclear Magnetic Resonance) สินค้าคุณภาพสูงจาก USA ขายราคาถูก
รายละเอียดเพิ่มเติม The HI1093B is a glass body, single reference junction pH electrode with a BNC connector designed to be specifically used to measure pH in NMR tubes. This pH electrode has a 3mm (0.11”) diameter and is 130mm (5.11”) long.
The 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 spherical micro bulb tip made from general purpose glass.
