The Alpha pH 800 controllers/transmitters combines consistent performance and sophisticated control functions with user-friendly features. Meters come with seven preset buffer values for quick, accurate auto-calibration; electrode offset function allows direct reading corrections without needing to remove electrode from the control system. Alarm delay and individual set-point hystereses in limit control mode prevent chattering, false alarms, and uncecessary down time.
::
2-in-1 controllers/transmitters can be configured to measure either pH or OPR (mV or %)
::
Auto-calibration with choice of NIST or USA buffer selection. Electrode slope and offset
is displayed after each successful calibration
::
Symmetrical mode option for clear, uninterrupted pH readings in electronically noisy environment
::
Antimony mode option for use with antimony electrodes in applications that involves corrosive Hydrofluoric Acid
::
Option of Auto or Manual Temperature Compensation. Three-wire system compensates for cable-length resistance errors
::
Galvanically-isolated, scaleable 0/4 to 20 mA output for high-quality output on peripheral devices
Applications

for any batch or on-line type application
that requires accurate pH or ORP control.
Water Purification/Treatment:
Use for batch and on-line control of incoming
process water, rinse water treatment, recirculating
system and waste water treatment.
Industrial:
Ideal for chemical processing, food processing.
aquarium, pharmaceutical, hydroponics and
waste control industries.
