7 Tubular sight glasses type 620 in special length
We produced these 7 tubular sight glasses in DN 80 PN 16 in a special length of 500 mm for our customer from the chemical industry. In order to be able to monitor his processes better, the standard length was extended from 200 mm to 500 mm. This enlargement of the viewing area by 300 mm enables our customer to better analyse and monitor the process.
Depending on the DN of the installation size, the possible viewing length can be safely extended up to 1000 mm.
