Our Core Technologies

Physical Parameter Measurement Instruments

We offer a wide range of sensors to measure critical physical water parameters. From temperature and turbidity to flow rate, water level, and electrical conductivity, our sensors are engineered for precision and ruggedness. These instruments help you continuously monitor the essential physical characteristics of water to ensure safety, compliance, and performance in dynamic environments.

Chemical Parameter Measurement Instruments

Our chemical sensors provide real-time insights into pH, ORP (oxidation-reduction potential), dissolved oxygen, ammonia, nitrates, chlorine, and total dissolved solids (TDS). Using electrochemical and optical technologies, our devices are ideal for high-accuracy detection in water treatment plants, aquaculture systems, and industrial processes.

Smart, Biological & IoT-Based Instruments

We provide cutting-edge biosensors and analyzers capable of detecting harmful bacteria like E. coli, heavy metals such as lead or mercury, and metrics like biochemical oxygen demand (BOD) and UV absorbance. These tools support advanced contamination alerts and regulatory reporting with the precision required for healthcare, environmental monitoring, and food processing sectors.
