Mercury-free, Ag-AgCl type, with sleeve junction. Designed for use with Thermo Orion ion-selective electrodes as indicated in respective descriptions; usable also with glass electrodes for pH measurement. Range 10 to 100°C. Length 140 mm, diameter 13 mm. Diameter of mounting cap 16 mm. Made entirely of plastic, which resists breakage and withstands acids, bases and organic solvents. Resistant to methanol, ethanol, glacial acetic acid, 25% nitric acid, 10% hydrofluoric acid and 10% sodium hydroxide. Transparent sleeve extends entire length, has filling hole near top. Sleeve cannot be dislodged accidentally. Can be disassembled for cleaning. Electrodes potential characteristics match those of a saturated KCl calomel electrode. If filled with saturated KCl in place of 4215F20 refill solution, characteristics match those of reference electrode with Ag-AgCl internal element and resulting range is -5 to +100°C. Includes 760 mm lead with pin-type connector and 2 oz. (60 mL ) dispenser bottle of filling solution.
