The Desktop Dissolved Oxygen Meter EZL-DDO121 measures dissolved oxygen in mg/L, ppm, or % saturation with a water-resistant membrane keypad and a simultaneous temperature display. The temperature measurement range falls from -10 °C to 110 °C with DO accuracy of ± 0.3 % and ± 0.4 %. An automatic pressure compensation of 80 kPa to 105 kPa can improve measurement precision and built-in automatic temperature compensation (ATC) of 0 °C to 100 °C for temperature variations.
