Hanna Instruments single-use pH calibration packets make calibrating your pH probe simple and fast. Just tear open the top, and stick your probe into the solution when performing the calibration procedure.\u003c\/p\u003e\n\u003cp\u003eOver the course of a couple months, it is common for pH probes to not read exactly correct and that can be fixed by calibrating your probe. Almost all monitoring devices will allow you to calibrate your pH probe, and a majority of them will let you calibrate your probe to a high and a low point. For saltwater aquariums, it is best to use a calibration solution with a pH of 7.0 for the low point and 10.0 pH for the high.\u003c\/p\u003e\n\u003cp\u003eIt is recommend calibrating standard pH probes every 3 months or as needed, where double junction pH probes can go up to 6 months before calibration is required.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch6\u003e\u003cstrong\u003e35 ppt Salinity Calibration Sachet\u003c\/strong\u003e\u003c\/h6\u003e\n\u003cbr\u003e\n\u003cp\u003eHanna HI70024 is a premium quality 35.00 ppt salinity calibration solution that is NIST traceable and contained in portable single-use sachets.
