Bluetooth Low Energy (BLE) provides convenient wireless communication with a mobile device or Windows computer, allowing users to configure the logger, perform guided pH calibration and download recorded data using the HOBOconnect app.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe MX2501 is designed for deployment in streams, rivers, lakes, estuaries and oceans, with a rugged PVC housing suitable for both freshwater and saltwater applications. The integrated potentiometric pH electrode has a plastic body, gel electrolyte and double-junction design, while an anti-biofouling copper guard helps protect the sensor during extended deployments. The pH electrode, battery and copper guard are user-replaceable.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe pH sensor measures from 2.00 to 12.00 pH with a resolution of 0.01 pH and accuracy of ±0.10 pH units within ±10°C of the temperature at calibration. The temperature sensor measures from -2 to 50°C, with ±0.2°C accuracy. Logging intervals can be programmed from 1 second to 18 hours, with both fixed-interval and burst logging modes available.\u003c\/p\u003e\n\u003cp\u003eWith 152 KB of memory, the MX2501 can store up to 43,300 measurements. The logger is waterproof to 40 m (131 ft)and features an IP68-rated enclosure. A water-detection system can help extend battery life by allowing Bluetooth to remain off while the logger is submerged. Depending on configuration and logging conditions, the user-replaceable AA battery provides approximately one to three years of typical operation.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003epH Range:\u003c\/b\u003e\u003cspan\u003e 2.00 to 12.00\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eTemperature Range:\u003c\/b\u003e\u003cspan\u003e -2°C to 50°C (28.4°F to 122°F).\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eAccuracy pH:\u003c\/b\u003e\u003cspan\u003e, ±0.10 pH units within ±10°C of temperature at calibration; \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eAccuracy Temperature:\u003c\/b\u003e\u003cspan\u003e ±0.2°C (±0.36°F). \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eResolution pH:\u003c\/b\u003e\u003cspan\u003e 0.01; \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eResolution Temperature:\u003c\/b\u003e\u003cspan\u003e 0.024°C at 25°C (0.04°F at 77°F). \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eResponse Time pH:\u003c\/b\u003e\u003cspan\u003e 1 minute typical to 90% at constant temperature in stirred water; \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eResponse Time Temperature: \u003c\/b\u003e\u003cspan\u003e, 7 minutes typical to 90% in stirred water. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eOperating Range:\u003c\/b\u003e\u003cspan\u003e -2°C to 50°C (28.4°F to 122°F), non-freezing. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eTransmission Range:\u003c\/b\u003e\u003cspan\u003e Approximately 30.5 m (100 feet) line-of-sight in air. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eLogging Rate:\u003c\/b\u003e\u003cspan\u003e 1 second to 18 hours. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eBattery Type:\u003c\/b\u003e\u003cspan\u003e One AA 1.5V. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eEnvironmental Rating:\u003c\/b\u003e\u003cspan\u003e IP68. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eDimensions:\u003c\/b\u003e\u003cspan\u003e 9\" x 1.68\". \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- \u003c\/span\u003e\u003cb\u003eWeight:\u003c\/b\u003e\u003cspan\u003e 9.46 oz.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe HOBO MX2501 data logger requires the \u003ca href=\"https:\/\/www.onsetcomp.com\/products\/software\/hobomobile\"\u003eHOBOmobile App\u003c\/a\u003e and a compatible mobile device. The system requirements for the HOBOmobile app can be found at the bottom of the \u003ca href=\"https:\/\/www.onsetcomp.com\/products\/software\/hobomobile\"\u003eHOBOmobile software page.\u003c\/a\u003e\u003c\/p\u003e","brand":"Onset","offers":[{"title":"Default Title","offer_id":45543982596227,"sku":"MX2501","price":1014.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2593\/8322\/products\/MX2501.jpg?v=1553875255","url":"https:\/\/dynamicaquasupply.com\/en-us\/products\/hobo-mx2501-ph-temperature-data-logger","provider":"Dynamic  Aqua-Supply","version":"1.0","type":"link"}
