It reads from -40 to 120 degrees F and uses a bimetallic sensing element inside a 9-inch stem to convert temperature changes into a mechanical dial reading. The housing and stem are constructed from 18-8 grade stainless steel, making it suitable for installations where corrosion resistance is required. Accuracy is rated at 1.0 percent of full scale. Connection is made at the back of the dial housing. Licensed HVAC technicians, plumbers, and mechanical contractors are the typical installers.\u003c\/p\u003e\u003cp\u003eThis thermometer is well suited for residential and light commercial HVAC systems, hydronic heating loops, domestic hot and cold water piping, and boiler installations where a reliable, direct-reading temperature gauge is needed. The 9-inch stem length allows it to reach the center of most standard pipes and ducts, providing an accurate reading of the fluid or air stream. The back-connected mount configuration integrates cleanly into panel-mounted or pipe-mounted instrument setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTemperature range of -40 to 120 degrees F covers typical HVAC and plumbing service conditions\u003c\/li\u003e\n\u003cli\u003e9-inch stainless steel stem reaches into pipe centers for accurate fluid temperature measurement\u003c\/li\u003e\n\u003cli\u003e18-8 grade stainless steel construction resists corrosion in wet and chemical environments\u003c\/li\u003e\n\u003cli\u003eBack-connected mount suits panel installations and inline pipe fittings\u003c\/li\u003e\n\u003cli\u003e1.0 percent full-scale accuracy meets standard mechanical instrumentation requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation bimetal dial thermometer for residential and commercial HVAC, plumbing, and hydronic system temperature measurement points requiring a back-connected, 9-inch stem instrument.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or plumbers. Shut off and isolate the system, and relieve pressure in the pipe or vessel before inserting or removing the stem. Use an appropriately sized thermowell or fitting to ensure a leak-free seal and to protect the stem from flow-induced stress. Verify the process temperature range does not exceed the thermometer's rated limits before placing into service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 120 degrees F (-40 to 50 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1.0 percent of full scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Back Connected\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WIKA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30090A002G4MM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51689136423218,"sku":"30090A002G4MM","price":153.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec70c41a58c454d4665daff87d776b04.jpg?v=1788255153","url":"https:\/\/voomisupply.com\/products\/wika-30090a002g4mm-bimetal-dial-thermometer-9in-stem","provider":"Voomi Supply","version":"1.0","type":"link"}
