Precisa ES420A Analytical Balances, Weighing Range 420g, SHANGHAI SHENGUANG INSTRUMENT CO.,LTD (CAT#: STEM-GLE-4724-LGZ)

All-aluminum gold casting base, anti-corrosion sealed keyboard. Streamlined visual effect, high strength, anti-static, no loopholes. Standard cylindrical hood (semi-micro and analytical balance), the unique cylindrical hood design greatly reduces the The air turbulence when opening and closing the door and the reserved space required for opening the hood, the design of the separate hood is easy to clean and does not affect the performance of the hood. The automatic infrared sensing device increases the safety of weighing and the convenience of use. (EP standard)

High-performance, high-integration electronic circuits. Minimize the number of electronic parts, solder joints, wiring, and lower energy consumption, which can make the instrument occupy a smaller area under the premise of ensuring stability and reliability. ( 0.01mg semi-micro balance host size: (WxLxH)240x360x345mm)
Electromagnetic balance weighing system with high magnetic energy core. The electromagnetic balance weighing system with high stability and quick response has the characteristics of corrosion resistance and impact resistance, and the repairable structure makes it more environmentally friendly and greatly reduces the user's cost of use.
Revolutionary balance structure. The main working modules are isolated, which greatly reduces the working air flow in the weighing chamber and achieves faster and more stable weighing results.
User-friendly man-machine dialogue mode. Large display screen with backlight LCD, EP series clear graphical menu, convenient text input and chart display functions, can make you handy to meet application needs.
Equipped with nearly complete application programs. Basic applications such as hanging weighing, unit preset, chart statistics, percentage weighing, recorder output, counting, statistics, clock, etc., standard pipetting calibration, buoyancy error correction, minimum Professional applications such as sample weighing.
Full-featured and easy-to-use communication functions. In addition to the standard RS232/USB interface that can be connected to printers and computers (standard computer software), it also has extended communication functions, and optional corresponding modules can realize USB expansion, Ethernet, wireless , Bluetooth and other communication methods, EP series can be connected to keyboards, storage, etc.
Fully automatic internal calibration system (SCS). If the SCS function is configured, the internal calibration can be manually started or the automatic calibration procedure can be started according to the set calibration conditions (time, temperature).
