Versatile meter can read dissolved oxygen concentration/saturation, plus up to 7 other water quality parameters for extreme convenience. Automatic salinity and manual barometric pressure compensation provides accurate DO readings in a variety of conditions. Easy one-button pH calibration can be performed with up to 3 points for better accuracy. One-point conductivity calibration with automatic standard recognition saves time. Additional features include memory for up to 400 readings, large backlit LCD, and auto power off. Measures DO in mg/L or % saturation, plus 7 other parameters Automatic salinity compensation and manual barometric pressure compensation for increased accuracy. Waterproof IP57-rated housing is ideal for field use
