Hanna Instruments HI 98150N Advanced Portable pH/ORP/Temperature Meter Review

The HI 98150 features IP 67 waterproof protection, GLP (Good Laboratory Practice) capabilities and use HANNA®' intelligent electrodes. These electrodes incorporate a chip which memorizes the calibration data performed with a specific instrument. When the "intelligent electrode is attached to the meter again, it is automatically recognized. This technology allows the operator to optimize time and efficiency with unsurpassed safety. It avoids erroneous measurement readings in the event that the pH electrode is substituted after calibration. This electrode series are equipped with a built-in temperature sensor; no need for an additional temperature probe here! The HI 98150 features all the most advanced features of laboratory pH meters. Moreover they are provided with a dual level LCD which enhances operability in dimly lit locations. By pressing a button, these meters can store up to 500 measurements complete with date and hour. Stored data can be displayed later or downloaded to a computer through an RS232 serial port and the HI 92000 Windows® compatible software.Range pH -4.00 to 19.99 pH Range mV ±600.0 mV; ±2000 mV Range Temperature -20.0 to 120.0°C Resolution pH 0.01 pH Resolution mV 0.1 mV (±400 mV); 0.2 mV (±400 to ±600 mV); 1 mV (outside) Resolution Temperature 0.1°C (-10 to 120°C); 1°C (<-10°C) Accuracy pH ±0.01 pH Accuracy mV ±0.2 mV (±400 mV); ±0.4 mV (±400 to ±600 mV); ±1 mV (outside) Accuracy Temperature ±0.4°C (0 to 70°C); ±1°C (outside)
