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 GMW’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. GMW also offers outstanding meter performance, providing exceptional accuracy, tracking and repeatability.

Higher Accuracy: 1% or better of Full scale or better
Position of use: Vertical (position) standard or to specified angle and/or position
Full scale deflection: 90 °
Movements: Taut Band
The absence of friction resulting from this permits greater sensitivities and provides more rugged meters.Common failures of conventional meters subjected to shock testing are cracked jewels and/or blunted pivots.
Pivot and Jewel
In this design the coil and pointer are supported by polished steel pivots at each end which fit into jewel bearings. Pivot and jewel meters are recommended for high vibration environments because of the mechanism’s inherent stability and strength. Accuracy and repeatability are almost equal to the taut-band’s, and good performance from the pivot and jewel construction is the reason for its long popularity.
