Not yet rated

Compact size is ideal for laboratory dissolved oxygen measurement applications

  • Large brightly-lit LCD shows allows for easy viewing of measured values
  • Low-maintenance galvanic probe requires no warm-up time
  • Built-in memory stores up to 100 data points

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 20 mg/L (ppm) or from 0 to 200% 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 provides greater precision by correcting for temperature variations between 32 to 122°F (0 and 50°C).

Large LCD features annunciators to aid in meter use and troubleshooting. Large display size makes viewing measurements easier. Meter is encased in a compact 6-1/8" L x 6-7/8" W x 2-3/4" housing which takes up a minimum of bench space. Water-resistant membrane keypad and convenient pullout reference guide provide useful features for the lab. Additional features include datalogging capabilities up to 100 points, a built-in electrode stand for convenient measurement, and selectable °F/°C temperature measurement.
