Overview
These time proven wattmeters, first introduced in 1977, are used by Biomeds & Physio-Therapists to calibrate or verify the accuracy of therapeutic and diagnostic ultrasound equipment. Power range is up to 30 Watts with resolution to 2mW. Frequency range: 1-10MHz. The UPM Series power meters meet FDA, AIUM, AMMI and JCAHO test requirements. The precision of these wattmeters is documented to perform within the limits of uncertainty of FDA and NIST standards. Direct power measurement, in watts, is made by converting the acoustical force applied to a cone target, linked to a mechanical balance beam or an electronic load cell. The UPM-DT models feature precise digital readout, autozeroing and a bi-directional RS-232 interface. All UPM Series Power Meters are supplied with a carrying case.
