2.1 Approved meter data
Approvals DK-0200-MI004-013
Standards prEN 1434:2009
EU directives Measuring Instrument Directive, Low Voltage Directive,
Electromagnetic Compatibility Directive, Pressurised equipment Directive
Heat meter approval DK-0200-MI004-013
The stated minimum temperatures
apply to the type approval only.
The meter has no cutoff for low temperature
and thus measures as low temperatures as
0.01°C and 0.01 K.
Temperature range θ: 2°C…160°C
Differential range ∆Θ: 3 K…150 K
