Escort Junior Temperature Egg Logger, 1x internal sensor, -20/60°C, memory 16.000. Escort Junior Egg Loggers, were originally developed for the US market. These loggers are designed to measure egg temperature in cartons during transportation and storage or during the incubation process. The egg logger can also be used in any other application that prohibits the use of other loggers due to size requirements. The logger case is made from ABS plastic, is of similar weight to a real egg and can be placed in a standard size egg carton. The Escort Junior Egg Logger is designed to operate in temperatures between -20ºC to up to +60°C. The logger has one internal sensor, which is situated in the centre of the logger to simulate the response time of an actual egg.
