Ammonia Meter AT-2000 for Semiconductor Manufacturing (Coulometric Method)
Measurement completed in about 1 minute. Rapid and accurate measurement of ammonia concentration in clean rooms.
In the semiconductor manufacturing industry's clean rooms, managing trace contaminants during the manufacturing process is crucial. Ammonia can adversely affect the quality of semiconductor devices, necessitating accurate measurement and management of its concentration. Colorimetric methods and ion electrode methods have faced challenges such as long measurement times and unstable results. The AT-2000 enables rapid measurement in about one minute, high precision, and easy operation, streamlining the monitoring of ammonia concentration in clean room environments. 【Usage Scenarios】 - Measurement of ammonia concentration in clean rooms - Management of ammonia contamination in semiconductor manufacturing processes - Measurement of ammonia concentration in wastewater treatment facilities 【Benefits of Implementation】 - Early detection of abnormalities through rapid measurement - Improved quality control through high-precision measurement - Enhanced work efficiency due to no need for calibration
basic information
【Features】 - Approximately 1-minute speed measurement (measurement range 0–20 mg/L), ideal for routine management and multi-sample measurements. - No calibration required. Eliminates the need for creating calibration curves or frequent standard solution calibrations, significantly reducing workload. - Less affected by color and turbidity. Stable measurements that are less influenced by sample characteristics. - Wide range of detection from low to high concentrations. Capable of measuring from a quantification limit of 0.05 mg/L up to a maximum of 200 mg/L. - Non-ionized ammonia (NH₃) can also be calculated. By inputting pH and water temperature, management of NH₃ concentrations harmful to fish can be achieved. 【Our Strengths】 Since our establishment in 1967, we have been committed to the development and dissemination of water quality measurement instruments. We aim to be a total solution provider that responds to all water environments by utilizing water quality measurement instruments, technology, and services.
