It uses an optical (luminescent) DO sensing approach that needs no membranes to replace and no electrolyte to refill, so there is far less to maintain than on a traditional Clark-cell DO meter — and no stirring dependency to bias a reading.\u003c\/p\u003e\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003eSuited to groundwater and surface water sampling, low-flow purge monitoring, aquaculture and fish hatcheries, wastewater aeration checks, and any field round where DO drives a decision. Automatic temperature compensation is built in, the sensor is user replaceable (order \u003cstrong\u003eRPT5\u003c\/strong\u003e), and a single N-type battery powers the pen.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDissolved oxygen and temperature in one pen\u003c\/li\u003e\n\u003cli\u003eNo membranes or electrolyte to service\u003c\/li\u003e\n\u003cli\u003eAutomatic temperature compensation\u003c\/li\u003e\n\u003cli\u003eUser-replaceable DO sensor cap\u003c\/li\u003e\n\u003cli\u003eWaterproof housing with fully encapsulated electronics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDocumentation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.myronl.com\/wp-content\/themes\/myron_l_theme\/dl\/PT5DS.pdf\" target=\"_blank\" rel=\"noopener\"\u003ePT5 Data Sheet (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.myronl.com\/wp-content\/themes\/myron_l_theme\/dl\/PT5OM.pdf\" target=\"_blank\" rel=\"noopener\"\u003ePT5 Operation Manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.myronl.com\/wp-content\/themes\/myron_l_theme\/dl\/PT5QS.pdf\" target=\"_blank\" rel=\"noopener\"\u003ePT5 Quick Start Guide (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eReplacement DO sensors, calibration solutions and accessories:\u003c\/strong\u003e see our \u003ca href=\"\/collections\/myron-l-parts-accessories\"\u003eMyron L Parts \u0026amp; Accessories\u003c\/a\u003e collection.\u003c\/p\u003e","brand":"Myron L Company","offers":[{"title":"Default Title","offer_id":48461671399614,"sku":"MYR-L-PT5","price":473.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/pt5.png?v=1785874595","url":"https:\/\/envirotechonline.com\/products\/myron-l-ultrapen-pt5-dissolved-oxygen-do-temperature-pen","provider":"EnviroTech Services","version":"1.0","type":"link"}
