It replaces laborious analog manifolds by delivering real‑time data for better decisions on the job.\u003c\/p\u003e\n\u003cp\u003eTwo temperature‑compensated pressure sensors deliver quick, accurate measurements of high and low pressure and automatically calculate evaporating and condensing temperatures. With two connections for external temperature probes, you can compute superheating and subcooling in real time. It also supports a temperature‑compensated leakage test to quickly confirm system tightness, comparing initial and end pressures. It stores 60 common refrigerants and offers an automatic heat pump mode for seamless hose switching. The robust metal valve block with three connections and three hose holders, together with IP42 protection and an illuminated display, makes measurements easy even in challenging environments. A suspension hook keeps the instrument secure during use.\u003c\/p\u003e\n\u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eUse the 2‑sensor setup for fast, accurate high\/low pressure readings and immediate evaporating\/condensing temperatures.\u003c\/li\u003e \u003cli\u003eAttach external temperature probes to calculate superheating and subcooling in real time, reducing manual comparisons.\u003c\/li\u003e \u003cli\u003ePerform a temperature‑compensated leakage test to quickly assess system tightness and detect leaks.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eModel: testo 549 digital refrigerant meter\u003c\/li\u003e \u003cli\u003eMeasuring temperature range: -50 to +150 °C • Accuracy: ±0.5 °C • Resolution: 0.1 °C\u003c\/li\u003e \u003cli\u003eProbe connections: 2 x plug‑in (NTC)\u003c\/li\u003e \u003cli\u003eMeasuring pressure range: -1 to 60 bar • Accuracy: ±0.5% of full scale • Resolution: 0.01 bar\u003c\/li\u003e \u003cli\u003eProbe connections: 3 x 7\/16\" – UNF\u003c\/li\u003e \u003cli\u003eOverload relative pressure (high pressure): 65 bar\u003c\/li\u003e \u003cli\u003eDimensions: 200 x 109 x 63 mm\u003c\/li\u003e \u003cli\u003eOperating temperature: -20 to +50 °C • Protection class: IP42\u003c\/li\u003e \u003cli\u003eRefrigerants in instrument: R114; R12; R123; R1233zd; R1234yf; R1234ze; R124; R125; R13; R134a; R22; R23; R290; R32; R401A; R401B; R402A; R402B; R404A; R407C; R407F; R407H; R408A; R409A; R410A; R414B; R416A; R420A; R421A; R421B; R422B; R422C; R422D; R424A; R427A; R434A; R437A; R438A; R442A; R444B; R448A; R449A; R450A; R452A; R452B; R453a; R454A; R454B; R454C; R455A; R458A; R500; R502; R503; R507; R513A; R600a; R718 (H2O); R744 (CO2) and many more (60 refrigerants stored as standard)\u003c\/li\u003e \u003cli\u003eIncludes: 1 x 549 Digital Manifold\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1 x Testo 549 Digital Manifold\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings \/ reminders\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eRefrigerants in instrument: 60 most common refrigerants stored in the instrument as standard.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eProviding quality and trusted service since 2002 at intercyprus.com\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"Testo 549","offer_id":54889358950742,"sku":"1005008920928875-Testo 549","price":376.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/Scb433adfef5b47ef91d4dd5cd42e12f4i.webp?v=1785828643","url":"https:\/\/www.intercyprus.com\/products\/testo-549-digital-manifold-gauge-refrigerant-pressure-gauge-2-valves-system-for-hvac-0560-0550-air-conditioning-pressure-meter","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
