EN13485 certifi cation
The ir33 platform range fi tted with the standard Carel NTC probe is compliant with standard EN 13485 on thermometers for measuring the air temperature in applications on
units for the conservation and sale of refrigerated, frozen and deep-frozen food and ice cream.
Designation of the instrument: EN13485, air, S, A, 1, -50 +90°C. The standard Carel NTC probe is identifi able by the printed laser code on “WP” models, or the code “103AT-11”
on “HP” models, both visible on the sensor part.
