1. In terms of use:
Laboratory pH electrodes are used for short-term intermittent testing under good environmental conditions; industrial pH electrodes are used for long-term continuous testing under poor environmental conditions.
2. In terms of performance:
Laboratory pH electrodes require good accuracy and repeatability of the electrodes and fast response; industrial pH electrodes require good long-term stability of the electrodes.
3. Structurally:
Laboratory pH electrodes are required to be simple and light, while industrial pH electrodes are required to have a solid structure, to be considered to be able to be installed, and to resist interference from various electric and magnetic fields.
