Smart Probes  are a new type of external probe developed by LogTag®.

Each Smart Probe contains its own electronics for measuring temperature. Calibrated temperature data are then transmitted to the logger to which the probe is connected. The logger acts only as a display and storage device. This means, the Smart Probe can be calibrated independent of the logger it is used with, and the logger itself requires no additional calibration.

You recognize the Smart Probe by its small case that holds the electronics conditioning and communication circuit:

The latest dual-channel loggers UTRED30-16 and UTRED30-WiFi are compatible with this probe, and also have hot-swap capability:

• You can connect a Smart Probe to channel 1, and an analogue probe to channel 2, and vice versa.
• You can swap a standard probe for a Smart Probe on the same channel, even during the same trip. The logger does not require re-configuration
• You can also swap a Smart Probe for a standard probe on the same channel.

The logger will display warning messages if the battery of the Smart Probe is low and requires replacement. This will be done by our distributor network at the same time a calibration is performed.

If you use an analogue probe, the logger's internal calibration is used. Smart Probes do not use the logger's calibration, instead, they each use their own calibration data.
