Getting Started
The T T hermo Scientific Alpha pH 560 Controller is used for
Description of
measuring pH and temperature values. The pH values can be measured
Instrument
using industrial combination pH sensors. The temperature values can
be measured using 3-wire Pt100 / Pt1000 sensors. The Controller can
be used for applications such as water treatment and controlling,
galvanic-decontamination, chemical processing, food processing, clean
or wastewater control and neutralization processes.
The pH Controller has many user-friendly and safety features which
include:
www.
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
High resolution ADC for precise measurement
Large dual display LCD for easy reading with clear
multiple annunciators, operational mode indicators and
error indicators.
Two switching contacts as set-point relays
Limit (on/off) control mode
Separately adjustable high and low set-point hysteresis
(dead bands) to prevent chattering of relays around the set
points
0 to 2000 seconds time delay adjustment on all relays –
minimizes false alarms
Backlight LCD display
