With a compact, space-saving design that is nearly 40% smaller than other benchtop meters, the DO 700 meter measures dissolved oxygen in mg/L, ppm, or % saturation with simultaneous temperature display in F or C. DO is measured from 0 to 30 mg/L (ppm) or from 0 to 300% saturation to meet the needs of a wide array of applications. Independent 100% and 0% calibration points provide accuracy over the entire range. Measurement accuracy can be increased by manual barometric pressure and salinity compensationmeter automatically calculates offset. Built-in automatic temperature compensation (ATC) provides greater precision by correcting for temperature variations between 32 to 122F (0 to 50C). Oversized display is brightly lit for easy viewing of measurements. LCD also features annunciators to aid in operation and troubleshooting.
