Industrial Multimeter
The 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, extended
operating temperature range of -15° C to
+ 55°C and 95% humidity, and a 3-meter
drop. They withstand hazardous 8.000
volt spikes caused by load switching and
faults on industrial circuits and complies
with second edition IEC and ANSI
electrical safety standards.
Furthermore, the 28 II has a unique
function for accurate voltage and
frequency measurements on adjustable
speed motor drives and other electrically
noisy equipment.
The new Fluke 20 series multimeters
are built to work in the toughest
environments.
