HI8424 Portable pH/ORP Meter with ATC and HOLD feature by Hanna Instruments
HI 8424 is one of the most popular pH meters on the market. This instrument is able to perform pH, ORP and temperature measurements with a high degree of accuracy and fast response.
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.
- Automatic calibration
- Automatic Temperature Compensation
- Automatic buffer recognition
- Three standard buffer values
- Calibration tags on LCD
- Low battery indicator
- Auto shut-off
- HOLD function
- ºC and ºF measurements
