Portable pH/ORP Meter with ATC and HOLD feature HI-8424

HI 8424 is one of the most popular pH-meter on the market. This instrument is able to perform pH, ORP and temperature measurements with a high degree of accuracy and fast response.

The HI8424 is a compact portable pH/mV/temperature meter that is supplied complete with a protective carrying case, PEI plastic body pH electrode, stainless steel temperature probe, calibration buffer sachets, and cleaning solution sachets. The meter features automatic calibration at one or two points as well as Automatic Temperature Compensation (ATC) when the temperature probe is connected.

Calibration is automatic at one or two points with three memorized buffer values (pH 4.01, pH 7.01 and pH 10.01). Once the instrument has been calibrated, the buffer values used during calibration are displayed with tags on the LCD. This feature keeps users informed of the current calibration and helps to avoid taking measurements that are out of range.

Exchange the pH probe for an ORP probe to obtain ORP readings in the mV range.

Order Information: HI8424 is supplied with HI 1230B pH electrode, HI 7662 temperature probe, battery, protective case and instructions
