The unit features a triple display that reads three parameters simultaneously, allowing technicians to monitor wet bulb, dry bulb, and dew point readings at the same time without cycling through screens. These measurements are essential for diagnosing air-conditioning system charge conditions, evaluating heating and ventilation performance, and assessing indoor air quality. Licensed HVAC technicians and mechanical contractors rely on instruments like the dth31 to make accurate load and comfort calculations in the field.\u003c\/p\u003e\n\u003cp\u003eThe dth31 is suited for residential and light commercial HVAC service work where psychrometric measurements are required. Typical applications include verifying system charge on split-system air conditioners, performing Manual J load assessments, evaluating economizer performance, and measuring entering and leaving air conditions across coils and heat exchangers. It is also used in ventilation commissioning and indoor air quality investigations where simultaneous wet bulb and dry bulb readings reduce total measurement time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTriple display shows wet bulb, dry bulb, and dew point readings simultaneously\u003c\/li\u003e\n  \u003cli\u003eHandheld form factor supports field use without bench setup\u003c\/li\u003e\n  \u003cli\u003eMeasures the core psychrometric parameters needed for HVAC system charging and load analysis\u003c\/li\u003e\n  \u003cli\u003eSupports heating, cooling, and ventilation diagnostic workflows\u003c\/li\u003e\n  \u003cli\u003eFast response time reduces wait between measurement locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose handheld psychrometer for use across residential and light commercial HVAC, refrigeration, and ventilation service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThe dth31 is a handheld test instrument and does not require permanent installation. HVAC technicians should allow adequate probe stabilization time before recording readings, following standard psychrometric measurement practice. Keep the sensing element clean and free of contamination that could affect humidity accuracy. Store the instrument in its protective case when not in use to prevent sensor damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Parameters\u003c\/strong\u003e: Wet bulb, dry bulb, dew point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: Triple simultaneous parameter readout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Handheld\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: UNIVERSAL ENTERPRISES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dth31\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UEI TEST INSTRUMENTS","offers":[{"title":"Default Title","offer_id":51162108657970,"sku":"DTH31","price":129.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306255598.jpg?v=1778890656","url":"https:\/\/voomisupply.com\/products\/universal-enterprises-dth31-digital-psychrometer","provider":"Voomi Supply","version":"1.0","type":"link"}
