The HAEFELY 3320 standard air capacitors are especially built for high accuracy dissipation factor (tan d) measurements or for calibrating measuring bridges together with the 3721.
Because of their high insulation resistance, small self-inductance and dissipation factor, these standard capacitors may be used within large frequency ranges.

Advantages
• Can be used in HV laboratories even at non-reference climate conditions
• Protected against dust and moisture
• It will advise when the draying agent (re-usable) must be dried
• Suitable for calibrations or reference laboratories
• Can be directly connected to Tettex measuring bridges manufactured since 1985.
