Alpha DO 1000 Dissolved Oxygen Controller/Transmitter
- Dissolved Oxygen Range Measurement range 0.00 to 20.00 mg/L ; 0.0 to 200.0 %
Overview
If you require an extensive measurement range of dissolved oxygen in ppm, mg/L or % saturation the Alpha DO 1000 controller/ transmitter is the perfect solution. This device is accepting of low range (0 to 10 ppm) and general range (0.5 to 40 ppm) probe, in addition this versatile controller/transmitter offers three dissolved oxygen modes: limit control. proportional pulse length control and proportional pulse frequency control.
The Alpha DO 1000 enables one point or two point DO calibration with electrode information is displayed after each successful calibration, previous calibration data is retained in the event of an unsuccessful calibration. Extensive accuracy features of the Alpha DO 1000 which enhance the users experience are automatic salinity and pressure compensation after each manual input and the option of manual of auto temperature compensation for enhanced accuracy.
Galvanically isolated, scaleable 0/4 to 20 mA output is a feature which provides high quality output on peripheral devices.
This product comes with a 1 year warranty.
