Having gained certification for accuracy class 0.05 last year, the METES 340 REF three-phase meter test system has now attained certification from the PTB (German National Metrology Institute) for accuracy class 0.02.

METES 340 REF from KoCost Messtechnik passed with flying colors for both accuracy classes and now has official confirmation of its high measurement accuracy and stability.

This high-precision test system is thus officially approved for use as a reference meter for testing electricity meters and bears the certification number 4869PTB08.

The METES 340 REF reference meter is ideal when the measurement accuracy requirements and other demands placed on a measurement mechanism are particularly exacting. METES 340 REF provides a wide range of functions with great reliability and flexibility.
