WD-35418-22 pH 620 Portable Waterproof pH Meter by Oakton

Expanded range, resolution and accuracy, increased memory, and advanced communications

These waterproof handheld meters feature a 2.00 to 19.99 pH range expandable to 0.001 pH resolution. Combined with accuracies up to ±0.002 pH, these meters provide a new benchmark in our pH meter line.

Store up to 500 data sets in the meters memory. Time-and-date-stamping meets Good Laboratory Practice (GLP) standards.

The pH 600 meters offer the latest in calibration capabilities including up to 6 calibration points, a user-settable calibration due alarm, and up to 15 buffer options with auto buffer recognition of USA, NIST, DIN, and PWB standards.

The infrared IrDA wireless technology makes PC downloading more convenient and easier. Dual power up allows you to use batteries while out in the field or the optional AC power adapter while in the lab.

As always, our waterproof meters are IP67-rated for both dust and water intrusion. Even with no probes attached!

• No more excuses for missing data! Out-of-date or unperformed calibrations are now things of the past!

WD-35415-01 DO 700 Meter with Probe and Probe Stand, with NIST Traceable Certificate of Calibration by Oakton

Compact size is ideal for laboratory dissolved oxygen measurement applications

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.

• Large brightly-lit LCD shows allows for easy viewing of measured values
