INTRODUCTION
Ultrasound Power Meter - Digital - 1 mW ResolutionOHMIC 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. The most reliable and repeatable means of measuring ultrasound power is the radiation force balancemethod. The transducer to be tested is centered above a 45° air-backed cone target in water media, which is linked to a precision balance capable of resolving 0.1 mg. OHMIC Instruments Models UPM-DT-1000PA, UPM-DT-10PA, and UPM DT-1 PA are precision wattmeters designed to measure the power output of diagnostic and therapeutic ultrasound transducers. |
