product description:

Use these premium quality general purpose electrodes to replace the electrode originally supplied with your hand held or bench-top pH meter. They are produced with epoxy bodies. All of our glass laboratory pH electrodes are supplied with a soaker storage bottle, making them instantly ready for use. Sensorex makes both separate and combination electrodes. The convenience of handling one combination electrode as compared to using separate pH and reference electrodes has been well established in laboratory and portable pH measurements. The price of Sensorex combination electrodes is much less than the total price of the separate electrodes. Individual half cell electrodes are used only for special purposes. pH electrodes to be constructed with sturdy and chemically resistant epoxy or premium ULTEM bodies. The recessed protected design of the Sensorex plastic body electrodes extends over the measuring surface, ensuring that the pH glass bulb is virtually unbreakable. Double junction designs use a buffering salt such as KNO3 in the lower chamber contacting the sample, and preventing these reactions. They are also useful for pH measurement of tris buffers. pH Range: 0-14 (Na+ error at >12.3 pH). Response 95 percent in 1 second (bulb-type only). Isopotential Point: pH 7.00 (0 mV). Offset: +/- 0.20 pH. Span: 97 percent of theoretical or higher. Application: standard lab use. Beer, wine and other liquors. Measures 12mm diameter by 150mm length.
