Constant Temperature and Humidity Weighing System LAHW, 10-60°C / 30-90% RH (CAT#: STEM-AL2-5471-ZJF)

The Constant Temperature and Humidity Weighing System LAHW is a controlled-environment weighing enclosure designed for gravimetric conditioning under controlled temperature and humidity. The chamber regulates temperature and humidity around filters or other gravimetric samples before and during weighing. An integrated high-resolution balance is supported within the conditioned work area according to the source configuration. Controlled airflow is used to maintain a stable local environment while limiting particulate disturbance. The enclosure materials and vibration-isolation measures are intended to support repeatable mass measurements. A computer-based control system manages the environmental settings and operating status. The work chamber provides space for conditioning and handling multiple filter formats. The system is suitable for gravimetric laboratory methods that require defined temperature and humidity conditions.
