Description
Elevate your water testing with the Hanna Instruments HI98128 pHep®5, a high-precision, pocket-sized tester designed for professionals who demand laboratory-grade accuracy in the field. Combining a dual-level LCD, advanced automation, and a rugged, waterproof housing, the pHep®5 is the ultimate tool for hydroponics, brewing, environmental monitoring, and laboratory use. Key Features Exceptional Accuracy & Resolution: Measure pH with a precision of ±0.05 pH and a high resolution of 0.01 pH. The expanded range covers -2.00 to 16.00 pH, ensuring versatility across various applications. Dual-Level LCD Display: View pH and temperature (°C or °F) simultaneously. The large screen also provides a battery percentage indicator at startup and a stability tag to let you know exactly when your reading is ready. Replaceable Electrode Cartridge: Unlike most pocket testers, the HI98128 features the HI73127 replaceable pH electrode. This cartridge design uses a sturdy stainless steel connector with no pins to break, significantly extending the life of your meter. Renewable Cloth Junction: The electrode features an extractable cloth junction. If the response time slows down due to clogging, simply pull out 1/8” of the junction to expose a fresh surface and restore the tester’s performance. Fully Waterproof & Floating: Designed to withstand the toughest environments, the housing is completely sealed against humidity and is engineered to float if accidentally dropped in a tank or vat. Advanced Automation: Automatic Calibration: Calibrate at 1, 2, or 3 points using two sets of memorized buffers (standard or NIST). Automatic Temperature Compensation (ATC): Integrated temperature sensor ensures all readings are adjusted for temperature fluctuations. Auto-Off Function: Preserves battery life by automatically shutting down after 8 minutes of non-use Technical Specifications Feature Details pH Range -2.00 to 16.00 pH pH Resolution 0.01 pH pH Accuracy ±0.05 pH Temperature Range -5.0 to 60.0°C / 23.0 to 140.0°F Temp.
