Calibrator PBC-TH28 model:
I would like to know if you perform the calibrator calibration, its recommended frequency and the price. On the other hand I would like to know if you could perform any adjustment in the calibrator in case it was necessary.
Could you send me the instructions of the calibrator to assure that we could manage it without problem or could you send an email adresss or movil phone to ask our doubts??
