Fluke - 9118A Thermocouple Calibration Furnace

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.

Accuracy specifications

All accuracy specifications except temperature are for a period of 1 year after calibration, at 13 °C to 33 °C

The furnace can be used with or without an Isothermal Block installed. Unique calibration parameters are necessary for each configuration. Calibration does NOT come standard from the factory for each configuration. Ensure that the furnace has been properly calibrated for the desired mode of operation.
