{"product_id":"horiba-isfet-non-glass-flat-ph-electrode","title":"Horiba ISFET Non-Glass Flat pH Electrode","description":"\u003cp\u003eThe HORIBA 0040N-10D is an ISFET pH electrode — a solid-state semiconductor sensor with no glass bulb. Its flat sensing surface measures pH on a droplet, a moist surface or a semi-solid sample, and because there is no glass membrane it will not shatter and needs no wet storage.\u003c\/p\u003e\n\n\u003cp\u003eISFET stands for ion-sensitive field-effect transistor. Instead of generating a voltage across a glass membrane, the sensor modulates current through a semiconductor gate in response to hydrogen ion activity at its surface. The practical consequences are what matter: the sensing area is tiny and flat, response is fast, the probe is mechanically robust, and it can be stored dry between uses rather than kept in KCl.\u003c\/p\u003e\n\n\u003ch3\u003eItems\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e0040N-10D\u003c\/strong\u003e (3200862858) — complete ISFET flat pH electrode, supplied with the 0141N sensor tip fitted.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0141N\u003c\/strong\u003e (3200862632) — replacement ISFET sensor tip.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eImportant compatibility note\u003c\/h3\u003e\n\u003cp\u003eThe 0040N-10D and the 0141N sensor tip are \u003cstrong\u003enot compatible with the older 0040-10D electrode\u003c\/strong\u003e.
