Noise, stuffy air, poor water quality or dangerous radiation and leaks compromise the well-being of people and the environment. To be able to test these factors reliably and mitigate them, if necessary, highly sensitive and precise devices are needed. Temperature measuring devices and hygrometers monitor the work and environment climate and provide a reliable warning when limits are exceeded or fall below specific thresholds. Special thermometers can monitor the temperature of food, for example. They can also be used to check if food is still edible after long periods of transport. IR cameras can quickly detect leaks in pipes or inadequate insulation. This means action can be taken swiftly, depending on the results. Force meters, on the other hand, determine forces that have an affect and weights of products.
