I have Tred30 -16u and Tred30- 16CP unit. Do these probes CP100 work with the Tred30 16CP unit ?? Why do these not come with 2 year calibrations?

This particular sensor is the CP100 which is compatible with the TRED30-16U along with the dual channel UTRED30-16 & UTRED30-WIFI loggers.

The CP110 sensor (https://microdaq.com/logtag-cp110-calibrated-smart-probe-kit.php) is ONLY compatible with the LogTag TRED30-16CP logger.
