Single-use packets mean every calibration starts with fresh solution, as HM Digital's meter manuals recommend.\u003c\/p\u003e\u003cp\u003eKeep packets at reservoir stations, in field kits and in the facility lab so operators can calibrate pH and EC\/TDS instruments on schedule in indoor cultivation and controlled-environment agriculture. These are the same pH 4, pH 7, 1000 ppm and storage packets HM Digital supplies with its HydroMaster monitors, and they can also be used with other brands of pH and EC\/TDS meters that calibrate to these values. Storage solution is for keeping pH electrodes hydrated between uses - calibrate with a buffer, not storage solution.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1000 ppm TDS Calibration - CP-1000, sodium chloride (NaCl) standard, 1000 ppm \/ 2000 uS (2 mS)\u003c\/li\u003e\n\u003cli\u003epH Electrode Storage - PH-PSTOR, potassium chloride (KCl) storage solution\u003c\/li\u003e\n\u003cli\u003epH 4.0 Buffer - PH-P4\u003c\/li\u003e\n\u003cli\u003epH 7.0 Buffer - PH-P7\u003c\/li\u003e\n\u003cli\u003eMixed Pack (1000 ppm TDS, pH 4, pH 7, Storage) - ASP-20, 5 packets of each solution\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e20 single-use 20 mL packets per box\u003c\/li\u003e\n\u003cli\u003eFresh, single-use solution for every calibration\u003c\/li\u003e\n\u003cli\u003eBoxes marked NIST traceable\u003c\/li\u003e\n\u003cli\u003e1000 ppm NaCl standard calibrates EC (2000 uS \/ 2 mS) or TDS meters\u003c\/li\u003e\n\u003cli\u003epH 4 and pH 7 buffers for one- or two-point pH calibration\u003c\/li\u003e\n\u003cli\u003eKCl storage solution keeps pH electrodes hydrated between uses to extend sensor life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRoutine calibration of pH and EC\/TDS pens, portable meters and continuous monitors\u003c\/li\u003e\n\u003cli\u003eRecalibration after installing a replacement sensor or probe\u003c\/li\u003e\n\u003cli\u003eOvernight and long-term pH electrode storage\u003c\/li\u003e\n\u003cli\u003eField kits for multi-room or multi-site checks\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Global Garden Company","offers":[{"title":"1000 ppm TDS Calibration","offer_id":53075647332663,"sku":"BL226252","price":24.95,"currency_code":"USD","in_stock":true},{"title":"pH Electrode Storage","offer_id":53075647365431,"sku":"BL226253","price":24.95,"currency_code":"USD","in_stock":true},{"title":"pH 4.0 Buffer","offer_id":53075647398199,"sku":"BL226254","price":24.95,"currency_code":"USD","in_stock":true},{"title":"pH 7.0 Buffer","offer_id":53075647430967,"sku":"BL226255","price":24.95,"currency_code":"USD","in_stock":true},{"title":"Mixed Pack (1000 ppm TDS, pH 4, pH 7, Storage)","offer_id":53075647463735,"sku":"BL226256","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/hm-solution-packets_1.jpg?v=1790824332","url":"https:\/\/www.blacklabelsupply.io\/products\/hm-digital-calibration-buffer-and-storage-solution-packets-20-x-20-ml","provider":"BLACK LABEL","version":"1.0","type":"link"}
