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.

The SL151T incorporates a magnetic swipe start function. The data logger can be configured ready to log but left in a dormant state until a magnet is swiped down the side of the data logger.

There are two members of this data logger family. The SL151T is the standard data logger and is supplied without a calibration certificate. The SL151T-A is supplied with a UKAS traceable calibration certificate and has an improved accuracy of ±0.2°C over the range -20°C to +25°C.

Cost effective starter kits are available containing either five SL151T or five SL151T-A data loggers, the inductive interface and TempIT-PRO software.

Choose the relevant product from the drop down list below the price above. The Inductive Reader is purchased separately and can be found in the accessories section.

The latest version of the TempIT-Pro software now automatically calculates the mean kinetic temperature ( MKT ) over the whole logged period or smaller intervals if the zoom function is used.

Signatrol offer an unconditional warranty on the SL151T. So confident are we in the robustness of this product the we guarantee it for 12 months against failure, and we will replace any unit that does fail within this period - regardless of cause!
