QAL1 certified stack monitor

QAL1 certified stack monitor for official emissions measurements

QAL1 certified by TUV to meet the EN 14181 standard, the S305 dust monitor is used for official emissions applications. The state of the art dust monitor has been used in stack emissions for a number of state owned and private industrial applications around the world.

Utilizing our unique Inductive Electrification principle, the S305 brings the reliability the government requires and combines it with the convenience plant operators expect from a particulate measurement device. With minimal maintenance required, this is an optimal solution for plant operators needing to measure stack dust emissions for government control..

ATEX Models

  • Certified for ATEX Zone 20, 21 or 22
  • Approved to Category II 1/2 for Gas and Dust
  • IP65 Enclosure, Custom Designed ● Certification Type: II 1/2 GD EEx ia IIC, T6, IP65, 85°C
  • Utilizing SINTROL’s Advanced Inductive Electrification Technology

The ATEX directive covers health and safety of workers potentially at risk from exposure to explosive environments. This directive classifies areas into Zone 0, 1, 2 for gas and 20, 21 or 22 for dust and guides plant operators to install the appropriate ATEX certified systems. Products are required to be categorized by the level of protection that they offer against the risk of them becoming a potential source of ignition in an explosive atmosphere. The equipment conformity categories are 1, 2 & 3.
