高精度差压表压力表

DESCRIPTION

The SERIES 2000-HA High Accuracy Magnehelic? Gage is twice as accurate as the standard Magnehelic? gage. The well-engineered High Accuracy Magnehelic? Gage offers a mirrored overlay as standard in order to eliminate any parallax error when taking measurements. A six point calibration certificate is included with each high accuracy model. The rugged IP67 casing helps fully protect against dust and water ingress. The redesigned corrosion resistant brushed 304 stainless steel bezel option offers a clean tapered design, yet minimizes the possibility of any dust accumulation on the edges.
