This device allows the status of fluid flow to be verified with the naked eye from both sides to accurately see whether the steam trap works properly. Special reinforced glass is applied for greater resistance to pressure. For the flapper type and ball type products, you can verify the status of even the subtlest flow.

This device allows the staus of liquid flow to be verified with the naked eye from both sides to accurately see whether the steam trap works properly.

This device allows the status of liquid flow and any leakages to be verified with the naked eye. You can check whether the steam trap is working properly and take necessary measures by looking at the overall status of the system. If the steam contains oxygen or carbon dioxide, there may be sediments accumulating on the glass surface. If this is the case, the water supply system of the boiler should be inspected to take measures to prevent corrosion.
