Precision Balances (CAH Series) (0.01 g to 5000 g) The CONTECH Precision Balances (CAH Series) are advanced high-precision laboratory balances engineered for accurate, stable, and reliable weighing across research, pharmaceutical, chemical, educational, jewellery, textile, and quality control laboratories. As a trusted manufacturer, supplier, and exporter of precision balances, CONTECH combines Electro Magnetic Force Compensation (EMFC) technology with advanced digital electronics to deliver exceptional weighing performance and long-term reliability. The CAH Series features a high-performance ADC circuit with inbuilt temperature compensation, providing outstanding stability with a resolution of up to 6 million counts. All calibration and adjustment parameters are programmable to compensate for minor assembly variations, ensuring highly accurate and repeatable measurements throughout the instrument's service life. The balance comes standard with a large white backlit LCD display, while optional display choices include a 5-inch Touch Screen Graphic Display and a Vacuum Fluorescent Display (VFD) for enhanced user experience. The bi-directional RS-232 communication interface enables seamless integration with computers, printers, and laboratory software, with an optional RS-232 to USB converter for modern connectivity. The CAH Series supports multiple weighing units including grams, ounces, troy ounces, carats, mommes, pennyweights, grains, tola, mesghal, and Chinese taels. Advanced weighing functions include percentage weighing, piece counting, fill mode, accumulation memory for up to 200 samples, multiple print formats, external calibration, adjustable response speed, automatic zero tracking, and stability monitoring. Optional features such as motorized internal calibration, 5-inch touch screen display, 21 CFR Part 11 compliance, GLP compliance with RTC, weigh-below hook for density determination, breeze shield, standard calibration weights, and VFD display make the CAH Series suitable for highly regulated laboratory and industrial environments. Designed for precision, compliance, and operational efficiency, the CONTECH Precision Balances (CAH Series) are ideal for laboratories requiring dependable high-accuracy weighing with advanced documentation and data management capabilities.
