2.1 Description of Instrument
The Alpha pH 550 Monitor is used for measuring pH and temperature values. The
pH values can be measured using industrial combination pH sensors. The
temperature values can be measured using 3-wire Pt100 / Pt1000 sensors. The
monitor can be used for applications such as water treatment and monitoring,
galvanic-decontamination, chemical processing, food processing, clean or
wastewater control and neutralization processes.
The pH Monitor has many user-friendly and safety features which include:
•
Push-button keypad for calibration and setup
• Built-in non-volatile memory to ensure that calibration and other
information are not erased if power supply fails
•
Menu-driven program that simplifies setup
• 1 or 2 point calibration with selectable USA or NIST standard pH
buffer set
•
Automatic temperature compensation (ATC)
• Manual temperature compensation setting without the ATC probe,
with independent setting for calibration and process temperature
• Large dual display LCD for easy reading with clear multiple
annunciators, operational mode indicators and error indicators.
