pHS-802AMain Features
Double row digital tubes display pH value/mV value and temperature respectively.
Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, instrument self-test, high accuracy, and good repeatability.
High reliability: Single board structure, touch sensitive buttons, no switch knob.
25 ℃ conversion: Nernst electrode slope temperature compensation, conversion for pure water and ammonia added ultrapure water at 25 ℃.
Input impedance>1012 Ω.
Waterproof and anti-corrosion design.
Automatic conversion of standard solution temperature: The temperature curve of the standard solution is pre stored, and the pH value of the standard solution at the set temperature is automatically converted during calibration.
Automatic identification of incorrect calibration: If the user uses standard buffer solution incorrectly during calibration, the instrument will automatically prompt.
Network function: RS232 bidirectional communication, compatible with printer or TLab1.0 communication and data processing software.
Industrial control watchdog: ensures instruments do not crash
Automatically prompt measurement endpoint

TLab1.0 software displays instrument parameters, measured values, and curves
Ordering Guide:It is necessary to inform the measured medium for easy electrode selection.
