SensoTech Inc.

SensoTech is the manufacturer of the advanced LiquiSonic® analytical technology that measures continuously in baths the concentration of cleaning agents and the contamination degree for an online bath monitoring.


As pioneer and leading provider of measuring technology for online bath monitoring, SensoTech has given first impetus to optimize the bath preparation and maintenance by inline measuring systems making the cleaning processes more safe, efficient and reliable. With over 25 years of experience, extensive technical know-how and innovative solutions, SensoTech is an expert in the field of online bath analysis.

Manufactured in Germany, our LiquiSonic® measuring systems set benchmarks that are used globally. With the SensoTech Inc., our U.S. branch in Wayne, New Jersey, we provide local customer support in the U.S. market.

Our LiquiSonic® measuring systems are used in cleaning and degreasing baths, rinsing baths, corrosion prevention and preservation baths or etching and pickling baths. The measurement of concentrations, such as the cleaning agent concentration, or the analysis of the contamination degree directly in the bath enable continuous bath monitoring in real time. The LiquiSonic® sensors measure the critical bath parameters ​​inline and provide the data online. The sensors are installed in pipes of any size or directly in the bath.

Measuring technique:
For the concentration determination, our LiquiSonic® technology is based on sonic velocity measurement providing accurate, repeatable and every second updated measuring results. Our sensors have proven successfully their process capability and convince through no maintenance and long lifetime.

Customer benefits:
It is our goal to maximize the efficiency and safety of your industrial cleaning processes. Using the LiquiSonic® technology, the re-dosing of the cleaning agent and the change of baths can be controlled accurately. This ensures an optimal cleaning result, improves facility capacity and reduces energy and raw material costs.
