Variations of this sensor are produced to also gauge underground temperatures using separate sensor units. The primary distinction between the DQA352 and DQA353 models lies in the DQA353’s enhanced accuracy regarding water film thickness and freezing point temperature specifications.

The DQA352 features an RS485 output with an open protocol, making it suitable for integration with LSI LASTEM and Boschung data loggers, as well as other third-party systems.

The DQA353, conversely, uses a Boschung proprietary protocol exclusively.

Both DQA352 and DQA353 sensors are manufactured by Boschung Mecatronic AG.
