Fluke Calibration 1504 - referenčný teplomer s presnosťou merania ±0,002 °C
Referenčný teplomer Hart Scientific 1504 pre vysokopresné meranie s termistorovými snímačmi. Termistory sú menej krehké oproti bežným odporovým snímačom teploty PRT, viac odolné voči mechanickému namáhaniu a viac citlivé na teplotné odozvy.
Štandardná presnosť merania ±0,002 °C pri excelentnom rozlíšení 0,0001 °C.
