Extech DO700 Multiparameter Meter Kit, includes pH/con/DO electrodes

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. What's Included: DO electrode, pH/ATC electrode, conductivity electrode, three DO membrane caps, one 30-mL bottle of DO fill solution, one 50-mL bottle each of pH buffers (4, 7, 10), one 50-mL bottle of 1413 µS conductivity calibration solution, two AA batteries, and hard carrying case. For full specifications please refer to the instruction manual 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
