Compact, space-saving design is nearly 40% smaller than other benchtop meters Extra-large 3-1⁄4" x 2-7⁄16" (8.3 x 6.2 cm), brightly lit LCD for easy viewing of measured values Low-maintenance galvanic probe requires no warm-up time 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 compensation—meter automatically calculates offset. Built-in automatic temperature compensation (ATC) provides greater precision by correcting for temperature variations between 32 to 122°F (0 to 50°C). Oversized display measures 3-1⁄4" x 2-7⁄16" (8.3 x 6.2 cm) and is brightly lit for easy viewing of measurements. LCD also features annunciators to aid in operation and troubleshooting. Setup function displays electrode slope and offset. Meter is encased in a compact 6-1⁄8"L x 6-7⁄8"W x 2-3⁄4"H (15.5 x 17.5 x 6.9 cm) housing which takes up minimal bench space—nearly 40% less space than comparable meters. Water-resistant membrane keypad and convenient pullout reference guide provide useful features for the lab. Additional meter features include datalogging capabilities up to 100 points, a built-in electrode stand that is switchable to either side of the meter, Hold function, and selectable °F/°C temperature measurement.
