Mastech MS8221B Manual Range Digital Multimeter offers the ability to measure temperature, DC current, DC and AC voltage, frequency and resistance as well as to test transistor hFE. The multimeter has a large 31/2 LCD with maximum displayed value 1999. Mastech MS8221B Manual Range Digital Multimeter allows to test semiconductor diodes and troubleshoot wiring; the results can be recorded by means of DATA HOLD function. In comparison with the other models, the measurement ranges in this device are narrowed and AC current measurement is not available.

Mastech MS8221B Manual Range Digital Multimeter designed to international safety standard IEC 1010-1 CAT III 600V, CAT II 1000V.
