NSnappy® Wash LWEU-N dishwasher transmitter

The wireless NSnappy® Wash is designed for the measurement of the temperature profiles of dishwashers.

The NSnappy® Wash transmitter is placed in the dishwasher with the dishes to be washed. Wash measures the temperature of the sprayed water on the dishes for the entire washing process. The device measures water temperature on the surface of the dishes; not the temperature of the water in the dishwasher reservoirs. The data is transmitted to the NSnappy® service over a LoRaWAN radio connection immediately after the washing is over.

The NSnappy® service stores an event for each washing session, and additional details can be added to it. By monitoring the development of washing events, you can anticipate the maintenance and adjustment needs of the dishwasher.

In normal use, NSnappy® Wash operates on the internal battery for five years. The measuring device comes with the NSure continuous warranty for IoT measuring devices.
