Enviko doesn't currently hold the official OIML R134 certification. This is mainly because the certification bodies are located in Europe, making the process very inconvenient for Asian manufacturers like us.
Instead, we adhere to the Chinese national WIM standard GB/T 21296. This standard is based on OIML R134 and is even slightly stricter. Enviko WIM sensors are widely used in China and globally, and their stability and accuracy have earned high praise from our clients.
