The DT4281 and DT4282 deliver the fastest response speed of any portable multimeter, improving the response time for DC measurement from previous models 1.5 seconds to 1.0 seconds. They also offer exceptional noise resistance and yield stable measurement results immediately after measurement. Faster measurement lets technicians perform their tasks at a higher level of efficiency. Thanks to safety performance that allows use in applications up to CAT IV (600V), the most demanding measurement category, and an operating temperature range of -15C to 55C, the instruments are safe and 100% reliable.
