Hart의 4채널 입력 온도 미터는 PRTs, thermistors, 그리고 thermocouples를 측정할 수 있고, 4개의 입력 채널에서 사용자가 임으로 8가지 데이터를 선택하여 디스플레이 가능합니다. 날짜와 시간 데이터를 포함한 8,000개의 판독치를 로깅할 수 있습니다. 그리고 배터리를 사용하여 8시간 까지 연속으로 사용 가능합니다.
휴대 및 거치용 온도 미터로서, 2 PRT와 2 T/C를 혼합 연결하여 온도를 측정할 수 있고 정밀 정확도가 높아 기준 온도 미터로 사용이 가능합니다. 그리고 휴대가 용이하여 출장 교정에도 적합합니다.
n Four channels for PRTs, thermistors, and thermocouples
n Displays eight user-selected data fields from any channel
n Logs up to 8,000 readings with date and time stamps
n Battery provides eight hours of continuous operation
