SẢN PHẨM
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.
HP-480TP is a pH meter with a time sharing proportional control function, making it ideal for tasks such as interval processing in any type of control process.
pH: 0 - 14
Temperature: 0 - 100 ℃
