Scientists have found through experiments that the pressure of\nliquid or gas increases with the increase of depth or height, which laid the\nfoundation for the later research on hydraulics and gas mechanics. Until the\nmid-19th century, a liquid level gauge based on pressure changes was invented,\nwhich provided a theoretical basis for the invention of the differential\npressure gauge.Differential pressure gauges are used to measure pressure\ndifferences between two locations and are commonly used in the following\napplications: flow measurement, air quality monitoring, level measurement, gas\nthermometry, and HVAC system control.Specifications:Accuracy:\n±0.3%FSLinearity\/hysteresis:± 0.1% FS of full scaleLimit maximum\npressure:6PsiRepeatability: ±0.25%FSFunctions：✓Backlit✓Data Hold✓Auto Power\nOff---25 mins without operation✓MAX\/MIN\/AVG\/DIF✓Zero SettingPackage\nIncluded:1 AP-189A Manometer1 Protective bag1 Small screwdriver2 1.5V\nBattery1 6 Languages manualAfter-sale Guarantee:Our handheld manometer comes\nwith 365 days warranty and lifetime technical support, if it has any product's\nquality problem, just get in touch with us, we will solve the problem for you\nASAP.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eHigh Accuracy ManometerAs a professional manometer with measurement range: +\/-2.000psi; Accuracy: +\/-0.3%FSO (at 25C) ; Repeatability: +\/-0.25%; Linearity\/Hysteresis: +\/-0.1%FSO; Limit maximum pressure:6Psi\u003c\/li\u003e\n         \u003cli\u003e11 Selectable UnitsEasily toggle between Psi, kPa, Kgfcm2, ozin2, Bar, mbar, inHg, mmHg, inH2O, ftH2O and cmH2O;Keep you work like a pro, Widely used in the following applications: flow measurement, air quality monitoring, level measurement, gas thermometry, and HVAC system control\u003c\/li\u003e\n         \u003cli\u003eData Record \u0026amp; Zero SettingThis Manometer would be record data, You can see the MAX\/MIN\/AVG value in this time, which help to easier to analyze the data conveniently; But before you did the measurement, you'll best try to set the zero setting first, long press the HOLD for 5 seconds, then it is zero setting\u003c\/li\u003e\n         \u003cli\u003eMulti-FunctionalProfessional manometer measuring Differential pressure, Positive and Negative Pressure, Data Hold, MAX\/MIN\/Average, Large LCD backlight, Low battery indicate, Auto Power Off, DIF Function\u003c\/li\u003e\n         \u003cli\u003ePackage Included1* AP-189A Manometer; 1* Protective bag; 1*Small screwdriver; 2*1.5V Battery; 1* 6Languages manual; This high-quality manometer is suitable for gas measurement systems, which measuring the air and ventilation system, calibrating and trouble shooting of gas pressure systems, HVAC, gas appliance repair and installation\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"AOPUTTRIVER","offers":[{"title":"Default Title","offer_id":45077123694743,"sku":"B0C1GFJYKR","price":209.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0461\/8380\/9175\/files\/B0C1GFJYKR.jpg?v=1737851336","url":"https:\/\/newnestshop.com\/products\/manometer-ap-189a-professional-gas-pressure-tester-dual-port-manometer-air-pressure-meter-11-selectable-units-differential-pressure-gauge-hvac-digital-manometer-with-backlight-data-record-ap-189a-6psi","provider":"NewNest Australia","version":"1.0","type":"link"}
