Garden Grove, CA: Dec, 2008   Sensorex announces availability of New "Calomel Free" pH electrode line to replace hazardous calomel pH electrodes. These electrodes are designed to produce a similar output to a calomel electrode so they can be used in place of the original calomel sensor. A custom chemistry emulates the output of the SCE which was the industry standard reference for decades. The hazardous materials in a calomel electrode are not environmentally friendly and are regulated. Until now, options were limited. For further information, request our CalomelFreeSpecs data sheet.
