Wireless pH Tester for Field with built-in specialized electrode Accurate, and easy to use, HALO2 Wireless pH Tester is ideal for field measurements due to its durability. The HI9810422 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 HI9810422 100 mm 75 mm 175 mm 012 mm Electrode Features PEI Resin Body The HI9810422 features a PEI resin body that is easy to clean and resistant to many aggressive chemicals. 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. Maintenance Free Gel-filled reference with no fill solutions required. Other than routine calibration and cleaning, this probe is maintenance free. 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 2.43 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.
