Panel-mount type conductivity meter
A conductivity meter for measuring a wide range from production water up to 500 mS/cm and enabling advanced concentration control with abundant outputs. Offering a lineup that includes sanitary sensors which no uneven surfaces and are stain resistant. The use of a panel mount converter allows for cost reduction at the time of installation.
Diverse lineup of sensors available
The sensor has a smooth structure without irregularities, providing resistance to dirt and less prone to contamination. Durable even under high pressure and high temperature conditions, making it ideal for chemical management in food production lines after CIP/SIP (Clean-in-Place/Sterilize-in-Place) processes. With two types of sensors: flow-through (inline) type, which is integrated into the pipeline, and insertion type, which is inserted into the pipe, various sizes and fittings to accommodate different requirements are available.
Possible to be used in a panel-mounted configuration.
This transducer is easy to install while providing standard functions.
