Ordering Information HI9810302 (HALO2) is supplied with a starter kit consisting of: pH 4.01 buffer solution, (2 pcs.), pH 7.01 buffer solution sachet (2 pcs.), Cleaning solution for soil deposits sachet (1 pc.), Cleaning solution for humus deposits sachet (1 pc.), Electrode storage solution (dropper bottle), Gelled bridge electrolyte (dropper bottle), 3V Lithium battery – CR2032, Instrument quality certificate, and Instruction manual Wireless pH Tester for Soil with built-in specialized electrode Accurate, and easy to use, the HALO2 Wireless pH Tester for Soil is ideal for agricultural, hydroponics, and greenhouse growers that need to monitor the pH of soil or soil slurries. The HI9810302 can be used as a stand-alone pH tester or can be connected to the Hanna Lab App. • The integrated Bluetooth module allows the tester to be connected to a compatible smart device with the Hanna Lab App • Compact, waterproof casing, and automatic pH calibration at up to three points, or four points when used with the Hanna Lab App. • Automatically temperature compensated readings HI9810302 75 mm 75 mm 150 mm 012 mm 05 mm Electrode Features Rugged PVDF Body The rugged PVDF electrode body is easy to clean. Resistant to most chemicals (e.g. solvents, sodium hypochlorite), ultraviolet light, and fungal growth, the PVDF body also has high-abrasion resistance and mechanical strength. Conical Tip The conical tip allows for easy penetration into soil or soil slurries. Fast, Stable Readings The double junction design presents a silver-free electrolyte solution interacting with the sample, making the electrode less susceptible to clogging and guaranteeing a fast response and stable reading. Built-in Temperature Sensor Built-in temperature sensor at the tip of the pH electrode allows for rapid determination of the sample temperature and a high-accuracy temperature reading. Easy pH Electrode Cleaning The PVDF outer junction sleeve can be removed and cleaned. Once cleaned, a small amount of supplied gel electrolyte is added and the junction is refreshed, improving the measurement and extending the life of the tester. pH solutions begin on page 2.158, pH electrode cleaning solutions begin on page 2.172 Hanna Lab App Compatible The Hanna Lab App is now compatible with Hanna Cloud and is available on the App Store® and on Google Play. 2 pH 2.44 | www.hannainst.com HALO2 App Store is a service mark of Apple Inc., Google Play and the Google Play logo are trademarks of Google LLC.
