Product Features
The Alpha DO 500 Transmitter transmits dissolved oxygen readings across a wide measurement range to the peripheral instrument of your choice, reliably and accurately.
:: Measures dissolved oxygen (in mg/L, ppm and % saturation) simultaneously with temperature
:: ±1.5 % full scale accuracy
:: Quick, easy calibration using atmospheric air as calibration media for 100 % air saturation
:: Push-button calibration – quick, easy, no hassle
:: High quality, high resolution output at chart printers and other secondary devices
:: Reliable, accurate measurements at different temperature with Automatic Temperature Compensation
:: Offset Adjustment Function allows you to adjust readings conveniently without having to remove electrode from the measurement tank or pipe
