Hanna Instruments HI-9810442 HALO2 Wireless pH Tester for Leather & Paper with built-in electrode
Accurate and easy-to-use, HALO2 Wireless pH Tester for Leather and Paper is ideal for measurements on flat surfaces, or small volume samples, with the specially designed flat sensing tip.
HI-9810442 HALO2 Wireless pH Tester for Leather & Paper with built-in electrode
The HI-9810442 can be used as a stand-alone pH tester or can be connected to the Hanna Lab App.
Features
- 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
- 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.
- The electrode features a non-porous glass body that is easy to clean and withstand harsh chemicals.
- Fast, stable readings thanks to the double junction design which 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
- Maintenance free – Gel-filled reference with no fill solutions required. Other than routine calibration and cleaning, this probe is maintenance free.
- Flat tip – Just one drop of water needed for the sample surface to provide an accurate measurement. Easy to clean.
- Stability tagging sends tagged results to the Hanna Lab App only after measurement stability has been achieved.
- The Hanna app is available on the App Store® and Google Play
HALO2 Wireless pH meter with Bluetooth® Smart Technology includes a dual-level LCD and temperature measurement for automatic temperature compensation. HALO2 pH probes can be used virtually anywhere as their versatility and ease of use will revolutionise the way pH is measured.
Accurate and easy to use, HALO2 wireless pH Testers are ideal for measurements in samples that would be a challenge for standard design pH electrodes.
The meters with their specialised electrodes can measure in the lab or out in the field. Then specialised applications: Cosmetic Creams, Soil, Wine, Beer, Meat, Chocolate, Bread and Dough, Cheese, Milk, Sushi, Skin, Leather and Paper.
Bluetooth Versatility
Connect to the Hanna Lab App via Bluetooth® wireless technology (10m range). The Bluetooth icon on the HALO2 LCD indicates the probe is active and transmitting.
One Button Sample Tagging
Pressing the button on the HALO2 pH probe or the probe icon in the Hanna Lab App will tag sample data for easy reference.
Easy calibration
HALO2 can be placed right into our calibration buffer sachets for easy calibration. Using a Hanna calibration sachet ensures your buffer is always fresh.
Easy to replace battery
HALO2’s CR2032 lithium ion battery is easily replaced and lasts for approximately 1,000 hours.
