HVS Series
Product Description
The HVS Series is our vacuum sensing series. These miniature pirani-type vacuum sensors allow measurements in a pressure range from 1000 mbar (atmospheric pressure) down to 10-3 mbar (HVS 04), and 10 mbar down to 10-5 mbar resp. 10-6 mbar (HVS 03k resp. HVS 03g). They come in a small and robust TO-39 or TO-8 metal housing. Assembling the HVS 04 and HVS 03g in a TO-8 housing allows coverage of the full pressure range.
