Panel-mount Type pH Meter (Four-Wire Transmission, 4 point ararm, Time sharing Proportional Control)
HP-960FTP industrial pH meter is a high-end pH meter with a four-point alarm and a time sharing proportional control function.
It connects pH sensor and measures pH and temperature in the sample water.
It can also be linked with a cleaning device via an external input, extending its automatic operation time.
Many types of electrodes are available to match the sample properties.
pH: 0 - 14
Temperature: 0 - 100 ℃
