NSnappy® Wash

Dishwashing measurement device

The Wash device is designed for mapping and monitoring the temperature profile of dishwashers.

The device is placed in the washing basket of the dishwasher among other dishes, where it measures the temperature of the water sprayed on the dishes throughout the process. Wash measures the temperature of the water on the surface of the dishes, not the temperature of the water in the washing machine’s tanks. The data is sent to the NSnappy service immediately after the washing process is finished.

The NSnappy service saves a washing event from each profiling, to which additional information can be added, for example about what kind of dishes were washed. By monitoring the temperature profiles of washing events, the need for maintenance or adjustment of the washing machine can be predicted.
