HI8424 Portable pH/ORP/Temperature Meter

Producer: HANNA Instruments

SKU: HANNA-HI8424 Category: Hanna experimental measuring equipment

– Measure pH and Temperature simultaneously.

– ORP can be measured with a separately purchased ORP electrode.

– Automatic calibration at 2 points

– Automatic temperature compensation.

– HI8424 meter comes with HI1230B pH electrode, HI7662 temperature probe, and calibration solutions.

– Convenient storage box

hi8424-2100x2100-d6dd524e-fff2-4d19-aae9-18f793f83dfe-1

AUTOMATIC CALIBRATION

At 1 or 2 points with 3 pre-programmed points (pH 4.01,7.01, 10.01)

HOLD BUTTON

The device has a HOLD button to help keep the pH value stable on the screen.

AUTOMATIC TEMPERATURE COMPENSATION

The HI8424 offers automatic temperature compensation from -20.0 to 120.0°C with the included HI7662 temperature probe.

The meter can also be compensated manually by entering the current sample temperature value into the meter when the HI7662 temperature probe is not present.

PH ELECTRODE WITH DURABLE PLASTIC BODY

Gel electrode without electrolyte filling, double junction.

The double junction design reduces internal reference cell interference that can cause precipitation of Ag/AgCl electrolytes leading to clogged junctions.

BNC CONNECTOR

The HI8424 has a BNC connector that is compatible with all electrodes that have a corresponding BNC connector.

CONVENIENT CARRYING BOX

HI8424 is supplied with HI1230B pH electrode, HI7662 temperature probe, pH 4.01 and pH 7.01 buffer solution sachets, batteries, instructions and rugged carrying case.

ORP ELECTRODE purchased separately when ORP measurement is required
