Safety Ohmmeter 1681A Armaments

The Safety Ohmmeter 1681A is a hand held tester that can be used to measure resistance values between 1 milli-Ohm and 20,000 Ohms.

The 1681A Safety Ohmmeter Armaments version has been specifically designed for safe resistance testing of squibs, detonators etc. The instrument is also approved for use in zone 1 and zone 2 hazardous atmospheres. The unit can be operated in its carrying case, which is also conductive.

The instrument enables measurement of low resistance of electrical bonds and wiring in electrical installations, contact resistance of circuit breakers and switches, the resistance of bus bar joints, fuses and detonators etc.

Thermal emfs and contact potentials have no effect on measurements as an ac system is employed. The Tester is ideally suited to continuity testing of wires in equipment with semiconductor devices having low break-down voltages.

The instrument is CE marked and compliant with the EU Atex Directive 94/9/EC for Potentially Explosive Atmospheres, Zones 1 & 2.

The instrument has been designed with the following features:-

Compact, light and robust
Digital display
Low Maintenance
Highly reliable
Easy to operate
Long Battery life
