Its waterproof compact design, large dual-display LCD, and automatic temperature compensation make it an essential tool for precise, on-the-go testing. With easy one-button calibration and smart battery management, it delivers lab-quality results without the hassle. ## Description The HI98107 features a large multi-level LCD which displays both pH and temperature readings simultaneously. The pH readings are displayed with a 0.1 pH resolution and with an accuracy of ±0.1 pH. The pH range of the HI98107 is from 0.0 to 14.0 pH. An exposed temperature sensor allows for rapid automatic temperature compensated pH measurements. Temperature can be set to display in ℃ or ℉. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. The pH electrode uses a unique reference cell design that utilizes a cloth junction that provides a larger surface area than a standard ceramic junction. Calibration is performed by pressing the dedicated calibration button. Once in calibration mode the pH electrode can be calibrated to 1 or 2 points using the pre-programmed standard buffers (pH 4.01, 7.01,10.01). When the standard value is recognized and stability is reached, the meter automatically accepts and stores the calibration value. Setup options include automatic shut off timing and temperature unit displayed. Automatic shut-off options are to turn the water pH meter off after 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment. Review: Very good quality for $$ selling price. - Right now, it is working just fine. Seemed to calibrate easily and holding the pH reading pretty steady. Review: It works well, but the manual SUCKS - The manual is a disaster. It instructed me how to change the temperature from degrees Celsius to Fahrenheit, only to learn later that this less-expensive model doesn't support that. Also, the initial calibration procedure is confusing and leads to concern about doing it all properly. After all, all we want is to accurately measure, pH, right? I have a ~1,000 gallon pond with goldfish that I want to take care of. The water chemistry tests that I use have us compare the water color to a chart. The tests work very well but for pH it's almost impossible to be confident of the reading. Hence, I bought this meter. Thankfully there is ChatGPT, which step by step held my hand to set it up and take the measurement. I now believe that what I thought was a pH of 6.5 (with the color comparison system) which might be hurtful to the fish is actually 7.4, which is perfectly safe for them. So, I knocked a star off their review. If they have a product manager that person should either be let go or taught how to be a product manager. Having been one myself this is the kind of thing that one just does as a normal part of the career. ## Features - Hanna HI98107 : easy-to-use pH water tester that makes monitoring water quality simple. - Compact Design : With its compact and portable design, this meter is perfect for on-the-go testing in various applications. - Multi Use : Great for drinking water, aquariums, pools, & ponds - PORTABLE : Handheld tester goes where you go. - EASY OPERATION : Features a user-friendly interface with simple button operation, making it easy to navigate and take measurements. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D98YW66V | | Best Sellers Rank | #273,248 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #248 in Swimming Pool Test Strips | | Brand | WLR Industries | | Brand Name | WLR Industries | | Color | Red | | Customer Reviews | 4.1 out of 5 stars 16 Reviews | | Included Components | cuvettes, reagent starter kit, battery, instructions and quick start guide. | | Manufacturer | WLR Industries | | Measurement Type | pH units, degrees Celsius, degrees Fahrenheit | | Min.
