Brightwin specially supplies high reliable precision analog multifunction current voltage signal generators with signal measuring functions. Brightwin multifunction signal generators support passive or active 0-20mA, 4-20mA, 0-5V, 0-10V, 24V signal output, and displays the signal in LCD or LED screen accurately. The current voltage signal generator has simple buttons or encoders to set parameters or to do programming. Some signal generator has internal embedded battery and 0-24mA, 0-12V signal measuring functions. All the 0-20mA 0-10V signal generators has user-friendly shell, very easy and convenient to use in the industrial site or in the lab.  These 4-20mA 0-5V 0-10V signal generator is the essential calibration tools for technicians, and save cost for developers.
