The Model UPM-DT-100SP Ultrasound Power Meter was developed to test therapeutic transducers according to AIUM, JCAHO, FDA, and NIST guidelines. OHMIC’s ultrasound wattmeters have been used worldwide since 1977 and are the most widely accepted standard for documenting the power output of medical transducers. The performance of the UPM-DT-Series has been tested and verified to be within the limits of tolerance established by the Food & Drug Administration (FDA) and National Institute of Standards & Technology (NIST). The compact and light weight Model UPM-DT-100SP meets all the requirements of a portable test instrument with the reliability and proven performance of the UPM-DT-Series. The Model UPM-DT-100SP uses the identical test tank and target configuration as the higher resolution UPM-DT-1 and UPM- DT-10.
