The instrument reads from -8 to 8 inches water column (WC) and is rated to a maximum pressure of 50 psi. A maximum operating temperature of 130 degrees F keeps it suitable for typical mechanical room and ductwork environments. The plastic body and case keep the unit lightweight at 1.875 pounds. HVAC technicians and test-and-balance professionals use this instrument to verify air pressure, duct static pressure, and gas appliance draft conditions.\u003c\/p\u003e\n\u003cp\u003eThe 1211-16 fits residential and light commercial HVAC service work where a portable, easy-to-read differential pressure gauge is needed. Typical applications include measuring static pressure across air handlers, filters, coils, and heat exchangers, as well as checking draft pressure on gas-fired appliances. The instrument's -8 to 8 inch WC range covers the pressure differentials most commonly encountered in duct systems and combustion equipment service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasures differential pressure from -8 to 8 inches water column\u003c\/li\u003e\n  \u003cli\u003e50 psi maximum rated pressure provides overpressure margin during testing\u003c\/li\u003e\n  \u003cli\u003e130 degrees F maximum operating temperature suits mechanical room use\u003c\/li\u003e\n  \u003cli\u003ePlastic body and case construction keeps unit lightweight and portable\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 24.75 inches overall height and 2.17 inches overall width\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose slack tube manometer for use in residential and light commercial HVAC, ventilation, and gas appliance pressure measurement applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this instrument should be performed by a qualified HVAC technician or test-and-balance professional. Ensure all pressure sources are isolated and depressurized before connecting or disconnecting tubing to the manometer. Verify that measured pressures will not exceed the 50 psi maximum rating to prevent instrument damage. Follow applicable local mechanical codes and equipment manufacturer guidelines when performing pressure testing and commissioning work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: -8 to 8 inches water column\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 50 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 130 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 24.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2.17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.875 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DWYER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1211-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DWYER","offers":[{"title":"Default Title","offer_id":51541726036274,"sku":"1211-16","price":235.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb07515e3ec3607d74f7562e646e8dbb_7451b01f-2284-4e4f-a5cd-2dbe03ea1690.jpg?v=1785883214","url":"https:\/\/voomisupply.com\/products\/dwyer-1211-16-slack-tube-manometer-50-psi-8-in-wc","provider":"Voomi Supply","version":"1.0","type":"link"}
