CY-FC Series Flameproof Balance (Internal Calibration)
The Aczet CY-FC Series Flameproof Balance is an analytical balance in a flameproof enclosure for hazardous areas. The CY 224FC reads 0.1 mg up to 220 g and has motorised internal calibration. Aczet states CIMFR Dhanbad certification for Zone 1 and 2, Gas Group IIB.
Overview
The Aczet CY-FC Series Flameproof Balance is made for laboratories and plants where flammable gases or vapours may be present, such as chemical, pharmaceutical, oil and gas, mining and defence sites. The CY 224FC is the internal-calibration model: 220 g capacity, 0.1 mg readability and 0.1 mg repeatability.
Flameproof construction
The electronics sit in a flameproof cum weatherproof enclosure with a glass window. Aczet lists a cast aluminium rotary switch, water-resistant push buttons and double compression glands that keep hazardous gases or powders out of the enclosure. A protective cover is supplied.
Certification (Aczet statement)
Aczet states that CIMFR Dhanbad certification covers use in Zone 1 and 2 for Gas Group IIB as per IS/IEC 60079-0:2011. Please ask us for the certificate for the exact model before you plan an installation.
Weighing technology
The balance uses an electromagnetic force compensation (EMFC) weigh sensor and a built-in capacity tracker that helps prevent overloading. The motorised internal weight lets you calibrate without handling an external test weight.
Everyday use
A large backlit LCD, a built-in clock for GLP documents, a round bubble level and adjustable feet make set-up simple. Built-in applications include piece counting, percentage weighing, check weighing, density determination, formulation and statistics, and there is an RS 232C interface (USB optional).
Aczet also offers customised flameproof ranges on request. Tell our team your capacity and hazardous-area class and we will confirm the right model.
