Review: Great for calibration of PH meters. - The instructions must be followed precisely. Even the temp of the test water makes a difference. If your distilled water is not at 77 degrees, you need to adjust for that. We found that even if the ph tester says it can adjust for water temp, it will probably not, at least the first time you calibrate it. It took us a couple of times to realize that we could not compromise even the smallest. If it says 750ml of test water, it means exactly that, 750ml, not alittle less or more. If you follow the instructions, these will work well for calibration of your meter. Review: Easy to use - These buffers are easy to use because the instructions are clear and the reference values are provided on the back of the sachet. A single sachet lasts me for half a month in refrigeration using small portions to calibrate my sensor controlled by a micro controller. Recommended for use with any type of pH sensor! ## Features - Easy to use- No need to measure, just mix each packs with 250mL distilled water. - Total 15 packs-The set includes 5 pack of 4.01, 5 pack of 6.86 and 5 pack of 9.18 calibration solution powder for all pH needs. - Designed for portability- Individual sized packets can be tucked in drawer, bag or suitcase for travel.,easy to carry. - Save time and money-By mixing powders in a jar of distilled water, this lets you keep them longer and more readily available without needing more packets. - Wide range of applications-Ideal for testing pH balance of drinking water, pool, aquarium, RO system, Spa, or hydroponics. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06X3TKTBC | | Best Sellers Rank | #340,866 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #160 in Chemical Buffers | | Brand Name | ESEE | | Customer Reviews | 4.5 4.5 out of 5 stars (2,100) | | Item Weight | 1.44 ounces | | Manufacturer | Lanboon | | Material Type | pH buffer solution powder | | Sterility Rating | 4.01-9.18 | | UPC | 613706120110 | | Warranty Description | 2 years from the date of purchase | ## Product Details - **Brand:** ESEE - **Manufacturer:** Lanboon - **Material:** pH buffer solution powder - **Ph Range:** 4.01-9.18 - **UPC:** 613706120110 ## Images ![15-Pack pH Meter Buffer Solution Powder for Precise and Easy PH Calibration, PH Calibration Powder Solution 6.86,4.01,9.18 - Image 1](https://m.media-amazon.com/images/I/71wpfyo0amL.jpg) ![15-Pack pH Meter Buffer Solution Powder for Precise and Easy PH Calibration, PH Calibration Powder Solution 6.86,4.01,9.18 - Image 2](https://m.media-amazon.com/images/I/71vUoMgSg+L.jpg) ![15-Pack pH Meter Buffer Solution Powder for Precise and Easy PH Calibration, PH Calibration Powder Solution 6.86,4.01,9.18 - Image 3](https://m.media-amazon.com/images/I/714OR-ZBxaL.jpg) ![15-Pack pH Meter Buffer Solution Powder for Precise and Easy PH Calibration, PH Calibration Powder Solution 6.86,4.01,9.18 - Image 4](https://m.media-amazon.com/images/I/61nBxv4ts0L.jpg) ## Questions & Answers **Q: How often do i need to calibrate the meters?** A: Dear Elsa Aquino, Thanks for your questions for our pH buffer solution powder. How often do you need to calibrate the pH meter, which depends on how often you use the meter. The following information is for your reference: 1, If you find the testing result is not accurate, then you need to calibrate the meter. 2, If you haven't used the meter for a long time, then you need to calibrate it. 3, You need to calibrate the meter again after about 10 times use for the mter. Best regards Ellen from Esee Group **Q: PH test kit for soil?** A: Our pH buffer powder is for calibrating the pH meter, so it is only an accessory, can not use it to test soil directly. **Q: It sounds like I can mix the powder with distilled water into a glass jar and. How long does this mixture last, i.e. 30 days, etc?** A: Yes, you can mix the powder with distrilled water into a glass jar and the mixture can last for around half year, but the glass jar must be sealed. **Q: Can these be mixed and stored in sealable 'plastic' containers?** A: Dear S. Rich, Thanks for your question. Yes, you can mix and store our ph butter powder in a sealed plastic container, it is OK!
