Selection Guide :

Differential Pressure Meter LMDPM-A200 is a perfect instrument for accurate pressure monitoring in cleanrooms, HVAC systems, pharmaceutical labs, and critical environments such as hospitals or semiconductor facilities. Its ±500 Pa measuring range makes it well-suited for low-pressure differential applications like filter performance testing, airflow monitoring across isolators, or pressure mapping in containment areas. With a repeatability of ±0.2% FS and temperature tolerance from 0°C to 50°C, it ensures consistent and reliable performance in various environmental conditions. The data storage capacity of 16,000 samples supports long-duration experiments or compliance monitoring, making it valuable for research studies and audits. Selection should also consider certifications for cleanroom or regulatory use (such as ISO, GMP, or calibration traceability), helping users choose this model when accuracy, data logging, and application compliance are critical.
