Necessary for ion selective electrodes. The first portable pH meter on the market with this resolution. Automatic Buffer Recognition. The meter will automatically recognize pH 4.01, 7.01 and 10.01 buffers. Simple 2 Point Automatic Calibration.
Calibration is performed simply through the membrane keypad.
The calibration data is then stored in the microprocessor's memory and will remain, even when the meter is off. 3 Meters in 1. By utilizing an advanced microprocessor, HI 8424 is able to perform pH, ORP, ISE and temperature measurements with high accuracy and fast response. To make calibration even easier, the calibration trimmers have been removed and calibration is now performed at the push of a button. As an accessory, the HI 721312 is available.
