Gossen Metrawatt M227A MetraHit 27M Milliohmmeter, Multimeter

Gossen Metrawatt, M227A, MetraHit 27M Milliohmmeter, Multimeter and Data Logger, Temperature Meter

M227A Includes Only:

• 1 GH18 protective rubber cover with carrying strap
• 3-size AA NiMH storage batteries
• 1 KS17-S measurement cable set
• 1 abbreviated operating instructions
• 1 operating instructions D/GB/F
• 1 DAkkS calibration certificate

Features:

• 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 the conductor and contact resistance 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 a 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.

Applications:

• Measuring low-value contact resistances at welding seams and riveted joints
• DeterMination of low-resistance transitions at outer skins of aircraft (lightning protection, wicktest), and for general low-resistance measurements.
