METRA HIT 27M Features
• All-in-one:
Milliohm resistance meter, multimeter and data logger
Compact and rugged for service under harsh conditions and
laboratory use, a single device for many applications
• Kelvin connection (4-wire measurement)
Suppresses influence from conductor and contact resistances
on measuring results
• Measuring current can be selected according to the measuring task:
Adaptation to various resistance measuring requirements and
optimized battery service life
• DATA Hold
For quick, reliable measurement and storage of individual
measured values, e.g. voltages at discrete cells in batteries
and emergency power supplies
• Overload protection
Protects the instrument in the event of inadvertent connection
to mains power
• DAkkS calibration certificate as standard feature
Reduced operating costs for use within ISO 9000 quality
systems, documented traceability
• Operation with storage batteries
3 NiMH storage batteries are included as a standard feature.
METRA HIT 27I / METRA HIT H+E CAR Features
Includes all METRA HIT 27M functions plus:
• Insulation resistance tester
Testing with 50 to 500 V for components, cables and
conductors, for example in aircraft and in on-board electrical
systems
• LCD panel with background illumination
High contrast, even under adverse ambient light conditions
• Compact and multifunctional
Can be used advantageously in aircraft cockpits as well as in
other constricted spaces, which would otherwise require the
use of several individual instruments.
• Mains power or storage battery operation
Furnished with 3 NiMH storage batteries and a mains power
battery charger as standard equipment for optimized
instrument availability and low operating costs
• DAkkS calibration certificate as standard feature
Reduced operating costs for use within ISO 9000 quality
systems, documented traceability
Special version for use in explosive atmospheres: METRA HIT27EX, see
separate datasheet.
•The METRA HIT 27M
is a compact milliohm resistance meter plus multimeter and
thermometer for the measurement of low-value contact
resistance on aircraft outer skins (lightning protection, wick
test), and for general low-resistance measurements.
•The METRA HIT 27I
is used additionally for service and repair work performed on
airplane and helicopter electrical systems (voltage, insulation,
milliohm and temperature measurement).
In addition to its own multimeter functions for electrical
quantities, the instrument also includes a mega-ohm
measuring function with insulation test voltages of 50, 100,
250 and 500 V, as well as temperature measurement with
Pt100 and Pt1000 sensors.
• METRA HIT H+E
CAR
Megatester for service and repair
of electric and hybrid vehicles
(features and technical data identical with METRA HIT 27I)
