It reads pressure in inches of water column (WC) across a measurement range of -60.0 WC to 60.0 WC, with selectable resolution of 0.1 or 0.01 WC. Accuracy is rated at 0.4 percent of reading between -20 and 20 WC at 73 degrees F and under 90 percent relative humidity. The unit runs on a single 9-volt battery rated for 150 hours of use, with a low-battery LED indicator built into the accessory head. HVAC technicians and gas service pros use this tool for duct static pressure testing, gas appliance commissioning, and airflow diagnostics.\u003c\/p\u003e\u003cp\u003eThe amn2 is suited for residential and light commercial HVAC work where accurate low-pressure measurement is required. Typical applications include static pressure testing of air distribution systems, measuring gas supply and manifold pressure on furnaces and boilers, and verifying combustion air pressure differentials. The unit is compatible with dry, non-corrosive gases only. It operates in environments from 32 degrees F to 105 degrees F and 15 to 90 percent relative humidity, making it practical for field use in most service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of -60.0 WC to 60.0 WC covers most residential and commercial gas and air pressure applications\u003c\/li\u003e\n\u003cli\u003eSelectable resolution: 0.1 WC standard or 0.01 WC high-resolution mode (divide displayed value by 10 when 0.01 WC resolution is selected)\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.4 percent of reading from -20 to 20 WC at rated conditions\u003c\/li\u003e\n\u003cli\u003e150-hour battery life from a single 9-volt battery with low-battery LED indicator\u003c\/li\u003e\n\u003cli\u003eAuto power-off at 15 minutes to conserve battery in the field\u003c\/li\u003e\n\u003cli\u003eIncludes two 3\/16-inch I.D. flex tubes with gas pressure fittings and a 5\/16-inch adapter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an accessory head compatible with the FIELDPIECE modular instrument system.

Always shut off gas supply and power to the appliance before connecting or disconnecting pressure taps. Use only the included or approved flexible tubing and fittings to maintain a leak-free connection at pressure ports. Do not expose the instrument to corrosive gases, condensing moisture, or pressures outside the rated measurement range.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: -60.0 WC to 60.0 WC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.1 WC or 0.01 WC (selectable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.4 percent of reading (-20 to 20 WC) at 73 degrees F, under 90% RH; 1.0 percent of reading (-60 to -20 WC and +20 to +60 WC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnits of Measure\u003c\/strong\u003e: Inches of water column (WC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Port\u003c\/strong\u003e: 3\/16-inch (4 mm) I.D. flexible tubing connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Dry, non-corrosive gases\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e: 32 degrees F to 105 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Humidity\u003c\/strong\u003e: 15 to 90 percent RH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: 9-volt (NEDA 1604 \/ JIS 006P \/ IEC 6F22)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Life\u003c\/strong\u003e: 150 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto Power-Off\u003c\/strong\u003e: 15 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: approximately 5.19 inches (H) x 2.44 inches (W) x 1.25 inches (D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: approximately 0.34 pounds including battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Accessories\u003c\/strong\u003e: Two 3\/16-inch I.D. flex tubes with gas pressure fittings, 5\/16-inch adapter with tube, battery (installed), operators manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FIELDPIECE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: amn2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FIELDPIECE","offers":[{"title":"Default Title","offer_id":51138399633714,"sku":"AMN2","price":97.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/AMN2_fieldpiece.jpg?v=1778255307","url":"https:\/\/voomisupply.com\/products\/fieldpiece-amn2-manometer-head-differential-pressure","provider":"Voomi Supply","version":"1.0","type":"link"}
