The performance of calomel electrodes is now available without the hazardous mercury associated with the design. The “Calomel Free” design features an Ag/AgCl based double junction reference with a unique silver ion trap acting as a third junction to impede any silver ion contact with the sample. Reference output is adjusted to deliver the same output as a calomel electrode using a silver chloride reference. As with all other Sensorex laboratory pH electrodes, the Calomel Free pH electrodes are supplied with a soaker storage bottle or soaker cap to make them instantly ready for use.

Electrodes are interchangeable with almost every make and model meter con the market today.
