Peripheric Combination Electrodes

Peripheric combination pH electrodes feature a highly durable glass pH membrane and a large peripheric ceramic reference junction. Ceramic reference junction is built in an annular form around the pH measuring glass electrode. Where streaming potentials in high purity water exist or where high solution currents prevail, this reference junction feature is particularly important. This large annular reference junction allows use in solutions that would normally foul an average combination reference junction.
pH combination, glass body, general purpose, Ag/AgCl gel-sealed reference. 12 mm O.D. x 150 mm long. Range 0-14 pH, 0 to 100°C.
652-000-04 is single annular junction with a temperature range of 0 to 100°C.
652-200-04 is double annular junction. For areas in which the reference cell is poisoned by heavy metals, protein, sulfide, etc. Temperature range: 0 to 110°C.
