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.
pH: 0 - 14
Temperature: 0 - 100 ℃
