- Product description
Brief introduction
ACD-3151 Digital differential pressure gauge is a new gauge developed and produced ourselves with imported advanced foreign technology. It adopts ANCN most advanced micro power technology and software compensation technique, the key component and parts all imported, the body has been strictly assembled, tested and burn-in, which grantee the quality of gauge. This product has advanced design, complete specifications and easy installation. And can replace the traditional 1151 and 3051 series products, so it is the replace and renew product of old gauge. In order to fit the continuous improvement and development of domestic automation level, this series product has site display function with small shape.
