SL151T Temperature Data Logger

Brand: Signatrol Ltd

The SL151T loggers are single channel, temperature data loggers that record the time, date and precise temperature for later retrieval and analysis.

The data loggers are used in food, pharmaceutical , building management and other industries for temperature monitoring.

Typical applications include food safety, where vulnerable or high value products are sensitive to incorrect environmental conditions, which in turn could cause irreparable damage to goods that might not be obvious on receipt.

The data logger is sealed in a crevice free and robust plastic tag with no 'bug traps' connections or entries of any kind.

The tag can be conveniently located in a packing case, on a pallet or attached directly to the product.

This data logger series is particularly suited for cold chain applications to meet EN12830 for the monitoring of food produce in storage and transportation.

The SL151T has a user manifest containing all the details of the application. This could be the name of the area being monitored, the vehicle registration number, the batch number or just a description of the application.

The user manifest, together with alarm thresholds, are simply downloaded to the data logger by a wireless interface.

The same reader retrieves the stored readings which are transferred to a suitable PC or laptop where the flexible TempIT software displays all the information in an easy to read graph, showing clearly if the consignment has been subjected to alarm conditions.

The readings are stored in a form that cannot subsequently be altered or manipulated whilst the data logger also records who has read the information thereby ensuring their integrity.
