Thermo Scientific Alpha pH 1000 pH/ORP Controller/Transmitter

Product Features
The Alpha pH 1000 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.

For finer control, Alpha pH 1000 offers proportional pulse length control and proportional pulse frequency control, in addition to basic limit control.
:: 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

:: Alpha pH 1000 limit/proportional controller also offer two additional features: wash function for
scheduled electrode wash, and alarm relay function to alert when measurement crosses
the set points
