E2-class mass standards represent an exceptional standard of precision in mass measurement. Classed  (more)as E2 metrology class, they are characterized not only by their high accuracy, but also by their versatility for use in laboratories, industry or scientific research. Key features: High precision measurements Stability over Time Calibration and Strict Quality Control Versatility of Applications Cylindrical shape Nominal value: 1 kg

F2 Mass Standard - knob weights with adjustment chamber - set (1 g - 50 g), plastic box Number of pi (more)eces in the set: 8 weights 1 g i 2 g – solid masses without adjusting chamber

The HX5.EX scale is a modern weighing instrument assuring fast and reliable measurement in hazardous (more) areas classified as zones 1/21 and 2/22. To ensure precision and excellent measurement repeatability, high quality electronic components are used. The weighing platforms offered in wide range of dimensions and maximum capacities, this combined with excellent metrological parameters enables easy selection of an instrument that meets the most demanding requirements. Standard version of the scale is equipped with 2 serial, intrinsically safe RS232 communication interfaces, and with one RS485 interface. They facilitate cooperation with equipment intended for operation in hazardous areas. Possibility to add digital inputs/outputs extends the range of instruments compatible with the indicator by automatic elements compliant with ATEX directive. More demanding customers can use the IM01.EX module, installed in the safe area, which extends the available connectors by Ethernet, USB, 4-20mA/0- 10V analog outputs, Profibus DP and additional digital inputs/outputs. This enables cooperation with external devices: barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. Scale operation requires use of a dedicated PM01.EX power supply, which is not a standard scale component. To operate the scale, order a selected type of the dedicated intrinsically safe power supply. Power supply types: PM01.EX-1 - power supply for operation in ATEX area. Used when it is required to connect the power supply to voltage source placed in hazardous area. PM01.EX-2 - power supply for operation outside ATEX area. Used when power supply connection to voltage source is carried out outside hazardous area. Complex software enables carrying out many tasks connected with mass measurement, e.g. parts counting, checkweighing and statistics. The scales feature user-friendly graphic interface, which can be customized using widgets. This and the large colour display of high resolution guarantee easy and clear transmission of data on current process. Colour bar graph significantly influences performance by signalling whether the weighing result is within declared thresholds or not.

The mass standard is the foundation of accurate mass measurement, as it affects the quality and reli (more)ability of results in many areas. Its role in maintaining uniformity and in meeting measurement standards is crucial, making the mass standard an indispensable metrology component. Varied Standards: The set consists of 12 flat polygonal sheets and 9 cylindrical standards, providing a wide range of calibration options. High-Quality Accessories: The set also includes 2 pairs of tweezers, 1 brush and 1 pair of gloves, facilitating precise and safe cleaning and handling of the standards. Plastic Packaging: The weights are delivered in a durable plastic case, ensuring their safe storage and transport. *The mg unit mass standards are flat polygonal sheets. **The 1 mg, 2 mg and 5 mg mass standards are made of aluminum.
