pH FIELD & LAB INSTRUMENTS Portable pH/mV/ORP and Temperature Meter with RS-232 PHH-830 Basic Unit LCD Displays pH/Temperature or mV/Temperature Simultaneously pH Measurement 0 to 14 pH, 0 to 1999 mV Temperature 0 to 100°C (32 to 200°F) Temperature Compensation for pH Range ATC & MTC Data Auto Hold Memory Recall: Single Recording 99 Sets; Continuous Recording 99 Sets, Max 3000 Pts. Auto Power Off for 10 Minutes RS232 Interface Calibration for pH 7.00 and pH 4.00 Optional pH Electrode, Temperature Probe and Buffer Solution The PHH-830 pH/mV and temperature meter with RS-232 communication is economically priced for many applications. The PHH-830 features an auto data hold. Pressing and holding the “test toggle” key during measurement will cause an “A” to flash and then hold the LCD. The PHH-830 also features recording of 99 records and also has an RS-232 communication for datalogging.
