The HI98198 Optical Dissolved Oxygen Meter makes measuring the concentration of dissolved oxygen hassle-free. Optical DO technology doesn't require a minimum flow rate, so there is less drift in your readings. Perfect for the field or for the laboratory, the Quick Connect probe requires no membranes, no filling solution, and no warm-up time so you can measure without hesitation. Your meter comes complete in a rugged, custom carrying case for easy transportation.Optical DO technology for fast and stable readings, even in tough environments.Digital probe with Smart Cap Technology eliminates costly, tiresome membranes and solutions.An IP67-rated waterproof, rugged body makes this portable meter ideal for field use.

The DO 700 benchtop 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 measures 3-14" x 2-716" (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.

Oakton DO 2700 meter measures dissolved oxygen in mg/L, ppm, or % saturation with simultaneous temperature display in °F or °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 housing which takes up a minimum of bench space. Water-resistant membrane keypad and convenient pullout reference guide provide useful features for the lab. Meter meets GLP requirements — all calibration and measurement data is stored with a time/date stamp. Bundled self-stirring probe and bi-directional RS-232 make this meter ideal for BOD and other advanced dissolved oxygen applications. Nonvolatile memory stores up to 500 data sets to simplify documenting data. Oversized graphic LCD with backlight allows readings under all conditions.

These top-of-the-line waterproof meters offer single or multiparameter measurement capabilities to meet all of your testing needs. The IP67-rated housing allows use in dirty and wet environments without harm to the meter. Store up to 500 data points with manual or auto datalogging and download to computer or printer with the infrared (IrDA) wireless technology — no need for additional cords. User-selectable "calibration due" and set point alarms, automatic or manual standards recognition, and single- or multiple-point calibration provide flexibility in meeting your data quality objectives. The large, backlit graphic LCD shows the measured value and units, temperature, time, battery life, and menu options.
