Posted on Wednesday, 15 April 2020 at 01:04

In a recent statement, Thermo Scientific announced to discontinue a part of their product line for nuclear level and density gauges. What is the impact of their decision?

Thermo Fisher Scientific US has decided to discontinue their nuclear density gauge business. According to Thermo’s discontinuation notice, this decision was made after a careful review of their global operations and product portfolio. The announcement was made in their product bulletin of January 30, 2020.

In their bulletin, Thermo shares a list of products that will be gradually phased out without any replacement product. Thermo announced that service and support for the discontinued products will be offered until the end of 2024, subject to availability. Discontinuation of the US Nuclear Level and Density product line is effective from January 31, 2020.
