UPM-DT-1000PA

OHMIC Instruments Newest Model UPM-DT-1000PA provides the fastest response (under 3 seconds) and the highest resolution (0.001 watts) of any current UPM-DT. The UPM-DT series have been in use worldwide since 1986 and conform to the testing guidelines recommended by FDA, JCAHO, AAMI and AIUM. Power is measured by the radiation force balance method. The accuracy of the UPM-DT’s are traceable to NIST.

UPM-DT-1PA

OHMIC Instruments Models UPM-DT-1PA & 10PA are precision wattmeters designed to measure the power output of diagnostic and therapeutic ultrasound transducers. The UPM-DT series  have been in use worldwide since 1986 and conform to the testing guidelines recommended by FDA, JCAHO, AAMI and AIUM. Power is  measured by the radiation methodand the accuracy of the UPM-DT’s are traceable to NIST.

UPM-DT-100SP

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.

UPM-DT-50SP

The most reliable and repeatable means of measuring ultrasound power is by the radiation force method. The transducer to be tested is centered above a 45° air-backed 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.
