It features a 1.5-inch dial and a bimetal spiral spring sensing element that reads both Fahrenheit and Celsius scales. The connection is a 1\/2 inch NPT threaded fitting using a lead free brass thermowell with set screw. The case is zinc-plated steel with a Kostil Polymer window. Lead free construction meets current lead free installation requirements across applicable codes.\u003c\/p\u003e\n\u003cp\u003eSeries LFTB thermometers are suited for hydronic heating systems, chilled water lines, domestic hot and cold water piping, and general HVAC fluid monitoring. The center back-entry mount allows clean inline installation where space is limited on pipe runs. The dry-type design and compact 1.5-inch dial make this thermometer a common choice for commercial mechanical rooms, institutional facilities, and residential boiler and water heater applications where a compact, readable temperature indicator is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead free construction for compliance with lead free installation requirements\u003c\/li\u003e\n  \u003cli\u003e1.5-inch dial with dual-scale readout in Fahrenheit and Celsius\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch NPT threaded center back-entry connection\u003c\/li\u003e\n  \u003cli\u003eBimetal spiral spring sensing element for reliable, maintenance-free temperature indication\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel case with Kostil Polymer window for durability\u003c\/li\u003e\n  \u003cli\u003eDry-type design rated from 32 to 176 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation thermometer for HVAC, plumbing, and hydronic systems requiring a 1\/2 inch NPT back-entry bimetal thermometer with a 1.5-inch dial.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or HVAC technician. Shut off fluid flow and relieve system pressure before inserting or removing the thermowell. Apply appropriate thread sealant to the 1\/2 inch NPT connection per local plumbing code requirements. Tighten the thermowell set screw to secure the sensing element before restoring system pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Size\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount\u003c\/strong\u003e: Center Back Entry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 32 to 176 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Scale\u003c\/strong\u003e: Fahrenheit and Celsius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\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: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W-0121666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51672601755954,"sku":"W-0121666","price":67.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4413a973cb3c8cd24c2c267083b0e161.jpg?v=1787969682","url":"https:\/\/voomisupply.com\/products\/watts-w-0121666-bimetal-thermometer-1-5-in-dial-lead-free","provider":"Voomi Supply","version":"1.0","type":"link"}
