美國PTC 815CL帶惰性指針的精密雙金屬實驗室溫度計

Celcius (Temperature Range C  -15°to +65°) 

PTC?的815型號的目的是檢查校準實驗室，數(shù)據(jù)存儲區(qū)，飛機機艙，嚴峻的糧食倉儲區(qū)，控溫儲藏室，潔凈室，實驗室，以及大面積的環(huán)境測試精度的溫度。815F溫度測量范圍為F:0°至150°；815C的溫度測量范圍為c：-15°至+65°。 

儀器的側(cè)面設(shè)有排氣孔，以允許盡可能多的空氣流進入儀器。 兩種型號（815F和815C）都配有一個引用指針，指針可預(yù)置來得到一種對于臨界溫度的目視檢查。 PTC的產(chǎn)品型號815精密溫度計墻是我們最準確的溫度計，特點在于精度只有±1°F（±1/2°C）。 

PTC?'s Model 815 is designed to check precision temperatures of cal labs, data storage areas, aircraft cabins, critical food storage areas, controlled temperature stock rooms, clean rooms, laboratories, and large areas in environmental testing. The Model 815F operates across a range of 0°F to 150°F and the Model 815C across a range of -15°C to +65°C. 

The side of the instrument is perforated to allow as much air flow into the instrument as possible. Both models come complete with a reference pointer which can be preset to afford a visual check of an approaching critical temperature. PTC's Model 815 Precision Wall Thermometer is our most accurate thermometer, featuring an accuracy of ±l°F (±1/2°C).
