Economical industrial online pH controller, 3 points calibration, 4 to 20mA signal output. The meter is suitable for monitoring the pH of liquids in chemical, pharmaceutical, environmental protection and food industries.
Features:
• Economical industrial online pH controller is equipped with a standard pH electrode.
• 1 to 3 points push-button calibration with auto-buffer recognition.
• Selectable NIST or USA pH buffer standard.
• Automatic electrode slope display helps user decide whether to replace sensor.
• Automatic Temperature Compensation provides accurate reading over the entire pH range.
• Low and high alarm limits can be set by user and automatically activate an external device.
• 4 to 20mA output signal meets industry standard.
• Manual temperature calibration improves the measurement accuracy of meter.
• Selectable temperature unit (°C or °F) for different application requirements.
• System menu allows setting the 9 parameters, including the pH buffer standard, number of
calibration points, alarm limits, hysteresis value, etc.
• Reset feature automatically resumes all settings back to factory default settings.
