Assisting optimisation of sterilisation processes
The Signatrol Temp-IT universal data logging software now has F0 calculation functionality, specifically developed for the validation of anti-bacterial steam sterilisation and cooking processes
Both the low cost model SL150T and the top of the range SL151T use a patented wireless induction technique for set-up and data download, which means that the units have no plugs, sockets or entries of any kind that could harbour bacteria.
With food safety and quality high on the public agenda, the SL150 is designed to travel directly with food and provides a detailed time and date temperature profile over a measurement range from -30C to +70C.
This data can then be used to highlight any problems which may have occurred throughout a specific journey or process.

A new low cost logging tag, the SL51M from Signatrol, ensures temperature data continuum during storage and transportation
The data loggers are housed in fully IP68 sealed, crevice free, robust food grade plastic tags only 10mm thick and powered by long-life internal batteries.
The 150T can be selected to log at intervals from 1 minute up to 255 minutes and with the ability to store around 2000 readings, the unit gives a maximum storage time of 11 months.
The 151T provides the ultimate in features and can be set to record at intervals from 30 seconds to 100 hours.
With an internal capacity of 16000 readings, the unit can keep recording for more than four years, using a delayed start feature which can be set to coincide with a particular travel schedule.
Comprehensive and user friendly Windows software provides a simple set up procedure and the units can be programmed with the manifest details such as vehicle number, driver, destination, ship name, consignment number and container number.
A convenient through hole allows the tags to be security-sealed to the food consignment.
Stored data are easily downloaded via the base unit to a PC or laptop and can be displayed graphically or saved in a standard spread-sheet format.
Two LEDs indicate the status of the unit during and after logging.
A red light indicates that the unit has seen temperature excursions outside the preset limits for a preset time interval while the green light indicates that no problems have been encountered.
Data are stored in such a way that it cannot subsequently be altered to disguise what actually happened and the SL150 has already proved itself with leading supermarkets, food suppliers and manufacturers.
Although Signatrol expect the main application for the SL150 series to be within the food and allied industries, the units can also be used for a wide range of other commodities including blood products, pharmaceuticals and other temperature critical products.
The company is so confident regarding the ruggedness and reliability of the product that they are offering an unconditional 12 month warranty.
The SL 150 is just part of the extensive Signatrol range of standard and bespoke data loggers and recorders.
