S2006D 0 6 inH2O 0 1.5 kPa Ranges from ±0.25 inH2O to 100 inH2O Positive or Zero-Center Ranges Mounts in Industry-Standard Openings ±2% Accuracy Die Cast Aluminum Housing The S2000 series differential pressure gauges are low-cost, diaphragm-operated, mechanical pressure gauges. S2000 gauges can be used in applications for measuring positive, negative, or differential pressure with an accuracy of ±2% in most ranges. Applications include monitoring filter status, duct static pressure, room pressure, fan or blower pressure, paint booths, dust collectors, and cabinet purging along with many others.
