Cryogenic Temperature Sensor Probes

Although TEC 3000 use different temperature probes in liquid nitrogen freezers, the function is identical when compared to TEC 2000. The TEC 2000 uses only two wires and hence the temperature probe casing has a smaller diameter. On the other hand, the TEC 3000 uses three wire as a result it has a larger diameter (despite the fact that only two of those three wires are in use). They carry an accuracy of 0.12% in which both are 1000 ohm platinum RTDs. Keep in mind that the temperature with an precision of plus or minus 2°C is displayed by TEC 3000 controller.
