Portable pH/mV Meter - HI8424

HI8424

The HI8424 General Purpose pH/mV Meter is a highly accurate compact, waterproof, portable meter with a separate temperature probe for temperature compensated pH measurement.This meter has a BNC connection and can be used with many BNC style pH and ORP electrodes.

Compact waterproof design
Automatic Temperature Compensation (ATC)
Automatic one or two-point calibration

Features

Waterproof, heavy duty casing protects against water that would damage the electronics

Automatic calibration to one or two points to standard buffer values (pH 4.01, 7.01, and 10.01)

Automatic shutoff after 20 minutes to conserve battery life.

Low battery indicator is displayed when the battery life is at 5%

High resolution/accuracy mV range, switching resolution automatically from 1 mV to 0.1 mV when ORP readings are between -699.9 to +699.9 mV. The accuracy within this range is ±0.2 mV.

Comes complete with a protective carrying case, PEI plastic body pH electrode, stainless steel temperature probe, calibration buffer sachets, and cleaning solution sachets
