HP-480
Panel-mount Type pH Meter (Four-Wire Transmission)
HP-480 connects pH sensor and measures pH and temperature in the sample water. Suitable for monitoring and control of various production processes and wastewater treatment, etc. Many types of electrodes are available to match the sample properties.
Measuring range
pH: 0 - 14
Temperature: 0 - 100 ℃
Segment: Process And Environmental
Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.
- Easy pH correction
After immersing the pH poles in the standard fluid, simply follow the instructions displayed and press the ENT key.
The automatic correction process is plain and simple. - Automatic diagnosis function for faults in electrode properties
If there is an asymmetry potential, sensitivity or response speed in correction, the HP-480 automatically determines whether there is a fault in the pH electrodes, and displays an error message. - Compatible with five types of temperature compensation element
Five types of temperature compensation element are supported: 500 Ω, 6.8 kΩ, 1 kΩ, 10 kΩ and 350 Ω. - A line-up of lead-free pH electrodes
Uses lead-free glass. In addition, almost all sections of the pH electrodes, including lead wires and soldered junctions are lead-free. - 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.
