Fornace orizzontale ad alta perfoermance per taratura di termocoppie, sino a 1200°C
La fornace 9118A Fluke Calibration è orizzontale con range da 300°C a 1200°C. Impiegata in laboratori per la taratura in comparazione di termocoppie, in differenti settori: aerospaziale, automotive, energia, metallo, plastic.
Le line guida come l’ AMS 2750 e l’ EURAMET cg-8, richiedono che le termocoppie siano tarate nel loro intero range di utilizzo. Il range di lavoro della fornace 9118A da 300°C a 1200°C soddisfa la maggior parte delle applicazioni.
In caso l'inserto standard non dovesse essere utilizzabile, richiedete quotazione per inserto custom.
