Compact measuring instrument powered and controlled through computer USB interface.

USB pH Meter Zvětšit

Display of measured pH values, their recording and calibration is ensured by Microsoft Windows applications. USB pH meter is equipped with a BNC coaxial connector for combined pH electrode. USB pH Meter amplifies the signal, digitizes and processes data by program in the microcontroller. Two-point calibration constants are stored in the device memory. pH data transmitted to the computer are already corrected according calibration points. Due to the simple structure of a text communication protocol, it is very simple to implement USB pH Meter to your own solutions. USB pH Meter is supported by SISW Instrument Control Suite.
