• NEW-IMPROVED-super-miniature, super fast coated wire pH electrodes
• 100-micron diameter - ideal for monitoring fast pH changes in very small places

A solid state pH sensor with ideal characteristics over a wide pH range. Exhibits a larger Eo than conventional glass electrodes. Requires a separate reference electrode such as WPI's Dri-Ref Series. Beetrodes (except the NMPH2) connect to your pH meter via a BNC-terminated cable. Beetrodes generate mV readings on standard pH meters. To obtain pH-scale readings on standard pH meters, use BEE-CAL™, a small, battery-operated compensator (AA battery included) that adjusts the electrode offset potential so that Beetrodes will produce standard pH-scale readings.
