Semi Micro Balances (CAI Series) (0.00001 g to 60 g) The CONTECH Semi Micro Balances (CAI Series) are ultra-high precision laboratory weighing instruments designed for applications requiring exceptional accuracy and sensitivity. As a leading manufacturer, supplier, and exporter of semi micro balances, CONTECH integrates advanced Electro Magnetic Force Compensation (EMFC) technology with intelligent electronics to deliver outstanding weighing performance for pharmaceutical, biotechnology, chemical, research, analytical, forensic, environmental, educational, and quality control laboratories. The CAI Series features a high-performance Analog-to-Digital Converter (ADC) with inbuilt temperature compensation, providing excellent weighing stability with up to 6 million internal counts. Programmable calibration parameters ensure superior accuracy, repeatability, and long-term reliability under demanding laboratory conditions. These semi micro balances come standard with motorized internal calibration, allowing automatic calibration without external weights, ensuring consistent measurement accuracy and minimizing operator intervention. A large white backlit LCD display provides clear visibility of weighing results, while the enclosed weighing chamber minimizes air disturbances for highly sensitive measurements. The balances include a bi-directional RS-232 communication interface for seamless connectivity with computers, printers, and laboratory software. Multiple weighing units including grams, ounces, troy ounces, carats, mommes, pennyweights, grains, tola, mesghal, and Chinese taels make the instrument suitable for a wide range of laboratory and industrial applications. Advanced weighing functions include percentage weighing, piece counting, programmable fill mode, accumulation memory for up to 200 samples, multiple printing modes, external calibration support, automatic zero tracking, adjustable response speed, and GSM (Grams per Square Meter) measurement for paper and textile testing. Optional accessories such as a 5-inch Touch Screen Graphic Display, 21 CFR Part 11 compliance, GLP compliance with Real-Time Clock (RTC), density determination kit, weigh-below hook, yarn count measurement, denier measurement, anti-vibration table, RS-232 to USB converter, and standard calibration weights make the CAI Series ideal for regulated laboratories and advanced research environments. Designed for maximum precision, compliance, and operational efficiency, the CONTECH Semi Micro Balances (CAI Series) provide reliable weighing solutions for analytical chemistry, pharmaceutical development, biotechnology, nanotechnology, research institutions, universities, and quality assurance laboratories.
