These waterproof handheld meters feature a pH range up to -2.00 to 19.99 pH and resolutions up to 0.001 pH. Combined with accuracies up to ±0.001 pH, these meters provide a new benchamark in our pH meter line.

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

The pH 600 series of meters offers 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.In addition, the pH 620 meter is capable of measuring dissolved ion concentrations through the use of ion selective electrodes (ISE).

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!

Order pH probes separately.
