Hanna Instruments Laboratory Division has released the HI 8424NEW portable pH meter, offering the same performance of a top-of-the line microprocessor bench meter.
A custom microprocessor allows it to perform pH, ORP and temperature measurements with high accuracy and fast response. The mV measurements automatically switch from 0.1 to 1mV resolution when the reading reaches ±699.9mV. Temperature effects are automatically or manually compensated for, from 0 to 100°C. The meter has three memorised buffer values (pH 4.01, 7.01, 10.01) and automatic buffer recognition to avoid errors during calibration. When turned on the meter shows the percentage of the remaining battery life. Thanks to the hold function, the reading can be frozen on the display to be logged manually. Moreover, the temperature can be displayed in °C or °F, the user can enable or disable the auto-off feature, the acoustic signal and the back-lit display. The instrument also indicates on the display the buffer values used for the last calibration.
The HI 8424NEW is supplied with an HI 1230B pH electrode, an HI 7662 temperature probe, calibration and cleaning solutions, a battery, a protective case and instructions.
