Research-grade ion-selective performance in a waterproof unit.

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.

Meter comes with all-in-one probe and batteries.

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

The pH 620 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 adaptor while in the lab.

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