제 품 개 요
|
|
|
본 Model은 Digital 풍속계로서 풍속, 온도측정 및 반도체 센서를 채용한 정압 측정에 최적입니다.
|
|
|
내장된 Micro Processor의 Program에 의해 측정시간에 대한 평균치, 최대/최소치, 표준편차,
|
|
|
풍량을 자동연산 처리하여 자체 Memory에 저장됩니다.
|
|
|
종래의 제품에 비해 비약적인 경량화를 실현했고, 출력은 내장형 프린터, RS-232C, 아나로그
|
|
|
출력 등으로 용도에 따라 선택하여 사용할 수 있습니다.
|
|
|
조작이 쉽고 간단하여 환경측정을 비롯하여 제품검사, 공조관리, 통풍관리, 냉난방장치의
|
|
|
성능 측정에 최적입니다.
