The ultimate shirt-pocket DMM with frequency & capacitance
No hassle warranty
No waiting.
No shipping charges.
This shirt-pocket-sized meter is only 3/8” thick and weighs less than 3 oz. With full functionality offering AC and DC voltage to 600 V, resistance to 40 Megohm, capacitance to 3000 μF, frequency to 1 MHz, continuity w/beeper, and diode test.
Fully autoranging, this meter offers seven different measurement
functions with 27 full ranges of measurement. The digital display is oversized with large digits and an­nunciators. In spite of its size, this meter is fully safety rated to CAT III 300 V, CAT II 600 V and is UL approved. No other meter offers this small size with such performance and high safety ratings.
Measures AC and DC voltage, resistance, continuity with beeper, capacitance and frequency
Fully autoranging with 7 measurement functions and 27 ranges
Large oversize digital display with measurement results and the unit icon
