HE-480C
Panel-mount Type Conductivity Meter (Four-Wire Transmission, For Low-concentration)
HE-480C connects conductivity sensor (ESH /FS Series) and measures conductivity and temperature in the sample water. This is a highly functional model, with high-performance temperature compensation, and is applicable to a wide range of tasks, from managing pure water for use with semiconductors, to managing the quality of boiler water.
Measuring range
Conductivity: 0 - 2000 μS/cm, 0 - 200.0 mS/m
TDS: 0 - 2000 mg/L
Segment: Process And Environmental
Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.
- High-precision temperature compensation
The temperature compensation element used is a platinum resistance thermometer (Pt 1000 Ω).Temperature compensation suited to a range of tasks You can select the appropriate temperature compensation for the temperature characteristics of the fluid you are measuring. - Self-diagnosis function for sensor faults
The sensor automatically determines whether it has deteriorated, and displays an error message. - Uses lead-free solder
To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
