How to ensure food safety?
We have the solution just for you

Temperature exposition is critical to prevent bacteria proliferation and freshness. But if we can easily control a room or fridge temperature, the inside of the food will cool or heat at different rates. Our small data loggers can be inserted into small containers and tight spaces to monitor temperature precisely during the cooking or cooling process.

This is how you could use temperature data logging throughout your supply chain

Food temperatures

With a data logger in your food, you get a time stamp for every measurement. If a problem occurs in the temperature chain, you know exactly when it occurred or if there is a suspect trend due to faulty chillers or heaters.

Cook & chill Units

Insufficient speed in raising or lowering the temperature for cooking and cooling can be hazardous. You need a data logger with a fast temperature response to follow closely the temperature changes inside your food.

Walk-in coolers & freezers

Coolers and freezers may be problematic for temperature homogeneity throughout the entire space. Inexpensive data loggers in all corners will help identify warmer spots that can affect the quality and safety of the food.

Dry storage

Excessive temperature and humidity can be hazardous or affect the quality of food and should be monitored throughout the storage space between the pallets or containers to identify a source of excessive heat or humidity.

Canning & bottles

The food inside a bottle or a can will take more time to reach sterilization temperatures. It is important to monitor this with a data logger that will fit through standard bottle neck or small enough to fit inside a small can.

Flash freeze

Flash freeze requires consistency in all the products to get uniform cooling inside the food. This can be monitored better with small probe with very low thermal mass and located right in the middle of the piece of food.


Pasteurisation requires lower temperature, but it needs to be precise with high-resolution measurements inside the food container and at several locations throughout the pallet to ensure homogeneity of the process.


Sterilisation requires higher temperature and proper timing to kill sufficient bacteria while keeping the good taste of food. Data loggers inside the containers at different locations will ensure homogeneity of the process.

Dishwasher operating temperature

The dishwasher used for cleaning dishes and instruments must also ensure their sterilisation in the short period of operation, usually a few minutes. Temperature of the water is important and should be monitored regularly.


Tracking the temperature throughout the shipment of your products is critical. Inexpensive data loggers can record a time stamp for every measurement to ensure that the cold or hot chain have not been broken, and otherwise, when to correct the problem in the future.

Connection Clamp

Connection Clamp

The connection clamp can be used on both the iButton and iBee. The two sharp pins will go through the thin silicone layer of the iBee to contact with the DATA and Ground surfaces. A small rotation of the iBee on the pins will help in making the contact.

Temperature monitoring in the food industry is an important matter for safety. It is at the heart of the HACCP and of the Food Safety Management System. Every process must get certification from the authorities. At the same time, optimization of the process is needed to increase profit margins that are often very low. These two requirements need precise temperature measurements at numerous location and time.

Proper data loggers will provide the information needed to reduce or increase oven or autoclave heat, slower or increase the speed of conveyors, get more or less freezing capacity in the cooling stage. All seconds and degrees count for the safety of the food, and for the balance sheet at the end of the day.

The instrumentation useful to address these issues should have a good precision and resolution to ensure that the minimal temperature is reached for safety while not too high to cause energy losses or excessive process time. It should be small enough to fit in tight spaces, in can, bottles or a small doe and be able to run through all the cooking or cooling process. A small thermal time constant is essential to be able to read rapidly and precisely the temperature change. The data logger installed inside an imperial roll before being fried on a conveyer must have its sensor right in the middle of the roll with limited thermal mass to properly read the temperature rising right in the middle of the roll while in the fryer.

Since the instrument must be inside the food to properly monitor its temperature, it’s housing material must be approved for contact with food. Ease of deployment is important for efficiency in the certification or routine test, as the downloading of the data for analysis. Finally, it must be easy to clean and sterilize for another use.

Alpha Mach offers a good range of instruments, each with its temperature range, precision, size, thermal time constant for all cooking, freezing and sterilization processes. Contact us to get more information for your specific requirements.
