Resistance thermometers (RTDs)

Resistance thermometers are needed if pH electrodes are used, which have no temperature measurement on board.

All resistance thermometers have a shaft length of 120 mm (4.72 in), a diameter of 12 mm (0.47 in), and a temperature measurement range of -30 to +135 °C (-22 to +275 °F).
