 Laboratory Calibration Services

 

PALTIN International Inc., has capabilities and facilities to perform independent laboratory calibration of different EM based sensors and profile probes as well as real-time monitoring tests using Low Earth Orbit Satellite as well as Cellular Communication Field Monitoring Stations to communicate with our clients globally.

Dr. Ioan C. Paltineanu has contributed directly to the laboratory calibration and testing of different EM based soil water measuring sensors and probes in the last 25 years as follows:
