These high quality meters comply with DIN EN60051 (IEC51) requirements , with a standard accuracy of ±1.5% of full scale or better.
Gossen meters are designed for applications that require reliable, rugged instruments with high resolution readings. They are manufactured from self-extinguishing, polycarbonate housing or sheet metal housing . Scales are easily interchangeable for maximum scaling flexibility, along with Gossen's patent mechanical movements, making these meters ideal for any application.
The optimum scale display area allows for the use of large, easy to read numerals and divisions. Gossen also offers outstanding meter performance, providing exceptional accuracy, tracking and repeatability.

Elapsed time meters or hours run meters monitor "ON/RUN" time of plant and equipment allowing the user to perform functions such as production efficiency, cost estimating and service period monitoring for preventative maintenance etc. The time is measured in increments of 0.01h up to 99999.99 hours after which time the meter resets to zero. Meters are non resettable to prevent accidental resetting.

Maximun demand meters monitors the most economic use of cable, fusegear and transformers. The directly heated bimetal element indicates mean r.m.s. current over 8, 15, or 20 mins, and a red slave pointer shows the highest value reached. The reset knob is wire sealable. Scales are calibrated to match the C.T. primary plus 20% overload.

Dual instruments can be used to measure a wide range of currents and voltages, and save both space and time by requiring only one panel cut-out. These meters allow for independent measurement of two DC or AC current or voltage in one case.

Watt and Var meters self contained and are available to measure active power and reactive power in both balanced and unbalanced, single and 3 phase 3 or 4 wire systems. These Wattmeters are ideal for clear precise analog indication of power in applications such as power generation, industrial control panels and power distribution.

These Power Factor Indicators are suitable for generators or supplies operating in parallel. The four quadrant 360° scale calibrated cos ø 0-1-0 indicates forward (export) and reverse (import) power flow for inductive and capacitive loads.

Phase Angle meters indicate the phase displacement between current and voltage. Used in applications where the phase angle must be monitored, for example with tariffs having VAr penalties, or to optimise generator power delivery. The measuring system comprises a moving coil indicator and a phase angle transducer
