TECHMO 7780 Series Sensing Eye780 Amplifier-Integrated Electrical Conductivity Sensor

Manufacturer : TECHNO MORIOKA
Model: 7780 series

R1/4 connection port; amplifier-integrated electrical conductivity sensor, ideal for integration into small devices.

confirmation; Amplifier and sensor integrated; dc power supply; No water quality information provided; Analog output; Installation piping R1/4

This is an ultra-compact amplifier-integrated electrical conductivity sensor (conductivity sensor).
Its R1/4 connector size allows for space-saving installation.
Equipped with an analog output (4-20mA), it can be combined with control and display devices such as PLCs for water quality measurement and management.
It supports high water temperatures up to 90°C, making it suitable for use in medical and food processing equipment requiring hot water disinfection. (Pressure resistance requirements apply.)
