GENErAL DESCriPTiON & iNTENDED USE
3. GENERAL DESCRIPTION & INTENDED USE
HI9810302 is a professional wireless pH tester, part of Hanna Instruments HALO2 family.
• The integrated Bluetooth module allows the tester to be connected to a compatible smart device with the Hanna Lab App.
• The tester has a compact, waterproof casing, and automatic pH calibration at up to three points, or four points when
used with the Hanna Lab App.
• Automatically compensated temperature readings are displayed on a large LCD.
• Accurate and easy to use, the tester is ideal for agricultural, hydroponics, and greenhouse growers that need to monitor
the pH of the soil.
Operating Modes
The HI9810302 can be used as a stand-alone pH tester or connected to the Hanna Lab App.
The Hanna Lab App turns a compatible smart device into a full-featured pH meter. Features include: electrode condition,
GLP with time-stamp, live-readings, mV resolution, manual temperature compensation, stability criteria, calibration reminder,
pH (mV) and temperature alarms, tester ID, and data sharing.
Probe Features
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.
The conical tip allows for easy penetration into solids and semisolids.
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.
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 at the tip of the pH electrode allows for rapid determination of the sample temperature and a
high-accuracy temperature reading.
