pH Sensor Electrodes

New "Calomel Free" pH and Reference Electrodes from Sensorex offer the high performance levels of calomel electrodes without the hazardous mercury associated with the design. The mercury-free electrodes are available in a glass body or in virtually unbreakable, chemically resistant thermoplastic. The "Calomel Free" design features an Ag/AgCl-based double junction reference with a unique silver ion trap that prevents contamination with the silver-sensitive sample. The reference output is adjusted to deliver the same output as Calomel electrodes using a silver chloride reference. Versatile electrodes are available in a combination model featuring a pH measuring cell and reference cell in a single body, with separate reference half cells also available. They are available in both sealed and refillable reference styles. Both sealed and refillable styles are available. Gel-filled sealed references are maintenance free, while refillable designs extend electrode life with a refillable reference electrolyte. Highly accurate Calomel Free Electrodes feature a measurement range of 0-14 pH (0-12.3 pH without Na+ error with a rapid pH response speed of >95% in 1 second. They feature an isopotential point of pH 7.00 (0 mV), an offset of ±0.20 pH and a span of 97% or higher. The electrode operates up to a maximum temperature of 140°F (60°C).
