In our thermometry, temperature and climate\/humidity and radiation temperature laboratories, our technicians work with temperature control equipment from -80 \u00b0C to 1210 \u00b0C and from 5 % RH at 98 % RH from -10 \u00b0C to 95 \u00b0C. In the field of thermometry, esz AG also offers the lowest measurement inaccuracies and a comprehensive portfolio for the calibration of temperature and humidity measurements.[\/vc_column_text]\n\t\n\t\t\n\t\t\t\t\tOverview of quantities<\/span>\n\t\t\t\n\t\t\t\t<\/span>\n<\/a>\n\n\t\n\t\t\n\t\t\t\t\tOverview of measuring devices<\/span>\n\t\t\t\n\t\t\t\t<\/span>\n<\/a>\n[\/vc_column][vc_column width=”1\/2″][vc_column_text css=”.vc_custom_1715855456407{margin-bottom: 48px !important;}” el_class=”hero-img”]\"Measurement[\/vc_column_text][vc_single_image image=”43517″ el_class=”bubble-header”][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1699970146871{margin-bottom: 128px !important;}”][vc_column][vc_column_text]

Thermometers<\/h2>\n

The recording and calibration of temperature is of great importance in thermometry. By directly monitoring the temperature, quality criteria for various products (e.g. food, steel, plastics industry) are met, in which the evaluation has a direct influence on the control of production systems. We mainly use calibration baths (thermostat baths) with different media (ethanol, water and silicone oil) and dry block calibrators with different measuring ranges for calibrating insertion or immersion sensors. Using high-precision platinum resistance thermometers and thermocouples with minimal drift and individual correction values, we achieve the smallest measurement uncertainties from 20 mK. We even achieve 15 mK at the water triple point. The basic electrical variables for thermoelectric voltage and resistance are traced back to the electrical laboratory, which means that measurement uncertainties of less than 2 mK can be derived for temperature display and simulation.<\/p>\n

Infrared thermometer and pyrometer calibration<\/span><\/h2>\n

Non-contact infrared thermometers are calibrated on a black plate radiator which, together with a sharp-point pyrometer, enables the transfer of radiation temperature in the spectral range 8 \u00b5m to 14 \u00b5m and temperatures from -15 to 500 \u00b0C.<\/p>\n

In thermometry, pyrometry refers to all measurement methods that allow the temperature of surfaces to be determined. To do this, the technicians carry out an energetic or spectral evaluation of the thermal radiation emitted by the surface. Measurements are taken using a pyrometer, also known as a radiation or infrared thermometer.<\/p>\n

Thermography, on the other hand, could be defined as imaging pyrometry. Pyrometers enable a ‘point-by-point’ statement about the surface temperature of a measured object. The signal conversion (heat radiation from the object = measured value) is similar in the pyrometer and in the thermographic system and is subject to the same physical laws. Our eyes receive information that consists mainly of reflected light.<\/p>\n

Block calibrators, temperature control units and climate chambers<\/h2>\n

Block calibrators are characterised in accordance with DKD-R 5-4 (Calibration of block calibrators). With the help of high-precision Platinum resistance thermometers or precious metal thermocouples, the influencing variables such as instability, radial and axial homogeneity as well as the Determined display deviation.. Calibration for thermostatic baths is carried out in a similar way.<\/p>\n

We use measuring systems and procedures in accordance with DKD-R 5-7 to calibrate climate chambers or climatic chambers. This means that we can also offer customers from development or production a professional calibration of their devices. In our thermometry laboratories, we record the characteristic features of climate chambers at nine measuring points in the chamber volume and evaluate the statements about instability, inhomogeneity and the influence of radiation. The calibration also provides results on display\/setting deviations and the uncertainty of climate parameters under defined conditions.<\/p>\n

Relative humidity<\/h2>\n

Calibrating moisture meters requires the highest level of metrological expertise. Our accredited humidity laboratory is one of the laboratories with the smallest measurement uncertainties in Europe.<\/p>\n

We offer these calibrations in various humidity generators, e.g. the Rotronic HygroGen2-XL or in the climate chamber. Numerous climate chambers and temperature control units are available for this purpose in our laboratory area for climate\/humidity. In addition to capacitive and resistive humidity measuring devices\/data loggers\/transmitters, esz AG also calibrates high-precision reference standards such as dew point mirrors and dew point transmitters. The calibration of climate recorders, loggers and measuring devices is carried out in climate generators in a stabilised humid air flow. The reference standard is a high-precision dew point mirror which guarantees the traceability of the measured variable “relative humidity” via the thermodynamic relationships between absolute humidity (dew point temperature) and air flow temperature. At the same time, continuous validation against capacitive precision humidity sensors with short response times is carried out.[\/vc_column_text]\n\t\n\t\t\n\t\t\t\t\tLearn more<\/span>\n\t\t\t\n\t\t\t\t<\/span>\n<\/a>\n[\/vc_column_inner][vc_column_inner width=”1\/2″ el_class=”img-right”][vc_single_image image=”44592″ img_size=”full” style=”vc_box_rounded”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1699970184706{margin-bottom: 128px !important;}”][vc_column][vc_column_text][vc_row el_class=\"block-service\"][vc_column][vc_row_inner content_placement=\"middle\"][vc_column_inner width=\"1\/2\" el_class=\"service-img\" offset=\"vc_hidden-xs\"][vc_single_image image=\"50941\" img_size=\"full\" style=\"vc_box_rounded\"][\/vc_column_inner][vc_column_inner width=\"1\/2\" offset=\"vc_hidden-xs\"][vc_column_text css=\".vc_custom_1716371718572{margin-bottom: 32px !important;}\" el_class=\"home-service-text\"]\r\n
