Euro gauge Liquid filled industrial pressure gauge
(Đồng hồ áp suất (dầu) WISE P258, inox toàn bộ, chuẩn CE Châu Âu)
Model : P258 series
(Dòng: P258)
 
Service intended
 
P258 series are suitable for corrosive environments. Typical application includes : Chemical, petro-chemical, refining process, power generation, marine and food industry. The filled liquid absorbs vibration and pulsation.
 
(Đồng hồ áp suất P258 kết hợp dầu glycerin thích hợp dùng trong các ứng dụng đo áp suất thay đổi cường độ cao hoặc rung động mạnh. Đồng hồ áp suất P258 có thể dùng để đo áp suất các lưu chất ăn mòn cao, khí, ga, hay chất lỏng mà vật liệu inox 316SS có thể chống chịu được. Ứng dụng của đồng hồ áp suất P258 được dùng rộng tải trong nhiều ngành công nghiệp nặng như hóa chất, lọc hóa dầu, thép, xi măng, thực phẩm ....)
