ACCURATE TESTING OF ULTRASOUND THERAPY EQUIPMENT 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 watt meters 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 UPMDT-100SP meets all the requirements of a portable test instrument with the reliability and proven performance of the UPM-DT-Series. The Model UPMDT-100SP uses the identical test tank and target configuration as the higher resolution UPM-DT-1 and UPM- DT-10. ultrasound power is by the radiation force method. The transducer to be tested is centered above a 45° airbacked cone target in de-gassed water. The coupling is made to a precision balance capable of resolving ± 0.15 watts. When acoustic energy is applied to the cone, the resultant force is directly proportional to the total radiated power. The test tank is lined with sonic absorbent rubber to prevent acoustic reflection. The balance is programmed to convert milligram magnitude forces direct to a readout in watts with good resolution. Measurement accuracy of the power meter can be verified by placing a calibrated weight on the cone’s support arm. (The supplied 1 gram calibration weight equals 14.7 watts.) Model UPM-DT-100SP weighs only eleven pounds and is simple to set up. On battery operation, the unit can be used “on-site” for approximately 20 hours. Principle of Operation The most reliable and repeatable means of measuring WARRANTY: All products manufactured by OHMIC Instruments are warranted to be free of defects in material and workmanship for one year after delivery. Any equipment found to be defective within this period will be repaired or replaced
