It reads in four scales - uS, mS, ppm on the 0.5 (NaCl) scale and ppm on the 0.7 (442) scale - with automatic temperature compensation, so operators get a fast, dependable check of nutrient strength and water purity.\u003c\/p\u003e\u003cp\u003eUse the COM-100 to spot-check nutrient reservoirs, irrigation water, RO permeate and source water throughout indoor cultivation and controlled-environment agriculture facilities. The IP-67 housing is submersible and floats, push-button digital calibration works at any point within the meter's range, and the sensor is user-replaceable (model SP-C1) when it wears out.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCOM-100 meter - ships with translucent cap, 2 AAA batteries and lanyard\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeasures EC, TDS and temperature, with temperature shown on screen alongside every reading\u003c\/li\u003e\n\u003cli\u003eFour scales: uS, mS, ppm 0.5 (NaCl) and ppm 0.7 (442)\u003c\/li\u003e\n\u003cli\u003eEC range 0 - 9990 uS (0 - 9.99 mS); TDS range 0 - 8560 ppm (0.7 scale) or 0 - 5000 ppm (0.5 scale)\u003c\/li\u003e\n\u003cli\u003eTemperature range 32 - 130 deg F (0 - 55 deg C) with 0.1 deg resolution\u003c\/li\u003e\n\u003cli\u003eAccuracy +\/- 2%\u003c\/li\u003e\n\u003cli\u003eAutomatic temperature compensation (ATC) using three temperature coefficients\u003c\/li\u003e\n\u003cli\u003eIP-67 waterproof housing - submersible and floats\u003c\/li\u003e\n\u003cli\u003ePush-button digital calibration to any point within range; factory calibrated with a 1413 uS solution\u003c\/li\u003e\n\u003cli\u003eReplaceable, detachable sensor (model SP-C1)\u003c\/li\u003e\n\u003cli\u003eAuto-off, data-hold and low-battery indicator; approx. 100 hours of battery life on 2 AAA batteries\u003c\/li\u003e\n\u003cli\u003e18.5 x 3.4 x 3.4 cm (7.3 x 1.3 x 1.3 in); 127 g (4.5 oz)\u003c\/li\u003e\n\u003cli\u003eOne-year limited warranty on the meter and on the SP-C1 sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNutrient solution EC\/TDS checks in hydroponic and fertigation systems\u003c\/li\u003e\n\u003cli\u003eRO, DI and filtration system performance checks\u003c\/li\u003e\n\u003cli\u003eIrrigation and source water testing\u003c\/li\u003e\n\u003cli\u003eAquaculture, cooling tower and general water-treatment testing\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Global Garden Company","offers":[{"title":"Default Title","offer_id":53075644416311,"sku":"BL226246","price":74.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/hm-com100_1.jpg?v=1790824278","url":"https:\/\/www.blacklabelsupply.io\/products\/hm-digital-pro-series-com-100-pen-style-tds-ec-temp-meter","provider":"BLACK LABEL","version":"1.0","type":"link"}
