Sensorex's Mercury Free ph Sensors
Calomel-free pH and reference electrodes offer the high performance levels of calomel electrodes without the hazardous mercury associated with the design. They are available in a glass body or in virtually unbreakable, chemically resistant thermoplastic. They 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 are available in a combination model featuring a pH measuring cell and reference cell in a single body.
