esz AG calibration & metrology is among Europe’s leading and most modern metrology laboratories. Core competency is industrial calibration for T&M equipment. Tailored software solutions, an outstanding range of service and cost transparency characterize esz AG in 40 years of business
Tailored software solutions, an outstanding range of service and cost transparency characterize esz AG in 40 years of business. The calibration laboratory’s headquarters is Eichenau, located on the outskirts of Munich, Germany. Periodic quality assessment for test and measurement equipment is a fundamental requirement to nearly all existing quality assurance standards, norms and procedures. Furthermore, there is much greater reason to analyse and certify one’s own precision: Product safety. To clearly understand that test and measurement equipment is working within specifications, is the only means of trust upon measurement results. A requirement equally important to you and your customers.
Electrical calibrations support nearly all existing areas of research & development, manufacturing and technology including, pharma, food and environmental engineering. Electrical measurements are considered the flagship in modern day metrology (simply due to the fact that most quantities are transformed into an electrical signal at a test point). Since the early 1980s electrical calibration are without a doubt key to all laboratory activities at esz AG. Back in the day when adjusment and repair service were still esz AG’s core competition, esz AG pioneered industrial High-End calibration techniques, including the first AC/DC-calibrators, subject to use for military, aviation and pharma, only.
esz AG’s radio frequency laboratory is designated to be one of Europe’s best equiped radio frequency calibration laboratory and characterized with measurement capabilities up to 67 GHz. The RF-laboratory features redundant system comparison by cross referencing the radio time signal carrier frequency (DCF-77) against a GPS-signal resulting in measurement uncertainties of below 5 parts per trillion.The RF-Laboratory is equipped with state-of-the-art power analyzers, frequency, power of different connector systems enabling esz AG to be highly responsive.
Metrological evaluation and calibration for optical power meters, attenuators and OTDRs are increasingly important to automotive, telecommunications, high-end consumer electronics industries. esz AG’s fiber optical calibration system includes calibration stations for fiber optical wavelength, fiber optical power, attenuation and amplification ranges from 300 nm to 1750 nm.
esz AG’s dimensional calibration laboratory is an addition to the eletrical field and dedicated to widen esz AG’s scope of service towards mechanical engineering, vehicle, aircraft and aifiliated industries. Calibration engineers rely on state-of–the-art laboratory equipment at standard laboratory conditions of 20 °C ± 1 K (typically ± 0,5 K).
esz AG’s laboratories for pressure, balancing scales/ weight (mass), force, virbation, shock and accelaration are designed to provide additional calibration opportunities for industrial test and measurment equipment.
esz AG’s field thermometry, temperature and environmental measuring technology is dedicated to temperature ranges from -80 °C to +1100 °C. Best practise in thermometer calibration (contact and immersion probes) is to rely on calibration baths or thermostat baths and dry block calibrators. The latter provide, along stabillity and reliability, almost maintenance-free robustness and short response time at wide temperature ranges, whether utilized at the stationary laboratory or on-site. Standard platinum resistance thermometers indicate marginal drift and result in measurement uncertainties below 15 mK. Utilizing a triple point cell, measurement uncertainities far below 15 mK are realized at water’s triple point of 0,01 °C. Electrical base parameters for thermoelectric voltage and resistance are traceable to the electrical calibration laboratory, resulting in measurement uncertainties below 2 mK.
asset expert is a web-based software application dedicated to comprehensive test & measurement equipment management. The software architecture is designed to enable random access and does not require a specific system setup or hardware configuration.
With calibration expert, esz AG calibration & metrology has taken an important step towards process automation in the calibration laboratory. The specially developed software solution makes your laboratory management considerably faster, simpler and more efficient. It supports your calibration technicians, engineers and metrologists in the calibration and creation or handling of calibration certificates.
An increasing number of organizations rely on test and measurement equipment availability 24/7. Disposal even for a single day turns into to lock-out – a scenario not exactly worthwhile pursuing. esz AG’s mobile calibration service is dedicated to assist customers in defining alternate ways to keep down times in production, R&D, quality assurance and safety testing at a minimum. In line with traceability to national or international standards, on-site test equipment management is in safe hands. esz AG’s on-site calibration service provides customers with the same capabilities, in terms of calibration for portable test & measurement equipment or test stations/ systems, on-site as compared to capabilities at esz AG’s stationary calibration laboratory. The advantage is obvious: No shipping, no risk of transportation,limited administration effort whilst maximizing the availability of one’s own test & measurment equipment.
esz AG calibration & metrology is among Europe’s leading calibration laboratories. The vast number of DIN EN ISO/ IEC 17025 accredited fields and quantities confirm esz AG’s versatility and leading role.
The only way to rely on and retrace test and measurement equipment data, specifications and uncertainties is a calibration report or calibration certificate. Regarding the latter esz offer a unique feature: ISO-compliant and accredited calibration are identical in terms of traceability, accuracy, standards and concerning quality characteristics. There is no difference in procedure or requirements.
