Equipment
Opacity Monitor Test Equipment
Cal Check offers test devices for on-stack and off-stack opacity monitor testing. Each test device mounts easily onto your monitor and locks in place, isolating the monitor from the stack opacity so testing may be conducted while the source is on-line.
Contact us to confirm the appropriate device and filters for your specific monitor. Please include your monitor manufacturer and model when reaching out.
