ĐỒNG HỒ ĐO ÁP SUẤT WISE P239

 P239 test pressure gauges are designed to check the accuracy of pressure instruments. Its use expands to a laboratory instruments for research shops and test labs. External adjustable dial and zero adjustable pointers are available for some models. It is an excellent choice for the process applications where high accuracy is a must.
