2 Technical Data
2.1 Approved meter data
Standard EN 1434:2007, prEN 1434:2009 and OIML R75:2002
EU directives Measuring Instrument Directive, Low Voltage Directive,
Electromagnetic Compatibity Directive
Heat meter approval D
The stated minimum temperatures
apply to the type approval only.
The meter has no cut-off for low
temperature and thus measures as low
temperatures as
0.01C and 0.01 K.
Temperature range : 2C…180C
Differential range : 3 K…170 K
Cooling meter
Temperature range : 2C…50C
