Its backlit LCD shows pH, temperature and EC\/TDS at the same time, and it can be calibrated with a range of calibration solutions and buffers.\u003c\/p\u003e\u003cp\u003eWith 2 m (80 in) probe cables and AA battery power, the HM-200 travels between reservoirs, batch tanks and irrigation zones in indoor cultivation and controlled-environment agriculture facilities. Operators can save up to 20 readings during a walk-through and recall them later, and both the pH probe (SP-P5) and the EC\/TDS\/temp sensor (SP-C2) are replaceable.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eHM-200 meter - ships with SP-C2 EC\/TDS\/temp sensor, SP-P5 pH probe, protective sleeve, pH 4 and pH 7 buffer packets and 2 AA batteries\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeasures pH, EC, TDS and temperature; backlit LCD shows three parameters at once\u003c\/li\u003e\n\u003cli\u003epH range 0.0 - 14.0 (0.1 pH resolution, +\/- 0.1 pH accuracy)\u003c\/li\u003e\n\u003cli\u003eEC range 0 - 9990 uS \/ 0 - 20.00 mS; TDS range 0 - 9990 ppm; EC\/TDS accuracy +\/- 2%\u003c\/li\u003e\n\u003cli\u003eTemperature range 32 - 130 deg F (0 - 55 deg C), +\/- 1 deg accuracy\u003c\/li\u003e\n\u003cli\u003eScales: pH, uS, mS, ppm 0.5 (NaCl) and ppm 0.7 (442)\u003c\/li\u003e\n\u003cli\u003eAutomatic temperature compensation from 0.0 - 60.0 deg C\u003c\/li\u003e\n\u003cli\u003ePush-button digital calibration; factory calibrated for pH and EC\/TDS\u003c\/li\u003e\n\u003cli\u003eStores up to 20 readings; auto shut-off after 5 minutes\u003c\/li\u003e\n\u003cli\u003eSingle-junction Ag\/AgCl pH probe and conductivity sensor on 2 m (80 in) cables\u003c\/li\u003e\n\u003cli\u003eRuns on 2 AA batteries; approx. 5.5 x 2.6 x 1.1 in (14 x 6.6 x 2.8 cm)\u003c\/li\u003e\n\u003cli\u003eOne-year limited warranty on the meter and EC probe; six months on the pH probe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWalk-through pH and EC\/TDS checks of reservoirs and batch tanks\u003c\/li\u003e\n\u003cli\u003eIrrigation and runoff spot testing across multiple zones\u003c\/li\u003e\n\u003cli\u003eVerifying in-line controller and doser readings\u003c\/li\u003e\n\u003cli\u003ePortable water-quality testing for RO and source water\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Global Garden Company","offers":[{"title":"Default Title","offer_id":53075646185783,"sku":"BL226250","price":274.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/hm-hm200_1.jpg?v=1790824311","url":"https:\/\/www.blacklabelsupply.io\/products\/hm-digital-hydromaster-hm-200-portable-ph-tds-ec-temp-meter","provider":"BLACK LABEL","version":"1.0","type":"link"}
