Overview
The NEW standard for rugged
The NEW Fluke 27 II and 28 II digital multimeters define a new standard for operating in harsh conditions with the features and accuracy to troubleshoot most electrical problems. Both meters have IP 67 (waterproof and dustproof) rating, MSHA approvals (pending), extended operating temperature range of -15 °C to +55 °C (5 °F to 131 °F, -40 °C for up to 20 minutes) and 95 % humidity, and have been designed and tested to withstand a 3 m (10 ft) drop. The new Fluke 20 Series
Multimeters are built to work in the toughest environments.
Features
Measure up to 1000 V ac and dc
Measure up to 10 A (20 A for 30 seconds)
10,000 μF capacitance range
Frequency to 200 kHz
Extended ac voltage bandwidth– 15 Hz to 20 kHz (28 II), 40 Hz to 30 kHz (27 II)
Built in thermometer conveniently allows you to take temperature readings without having to carry a separate instrument (28 II)
Resistance, continuity and diode test
Min/Max and average recording to capture variations automatically
Peak min-max (28 II)
Unique function for accurate voltage and frequency measurements on adjustable speed motor drives and other electrically noisy equipment (28 II)
