Description
Combo® Low Range pH / EC / TDS / Temperature Tester – Hanna Instruments
The HI98129 Combo® is a compact, waterproof multiparameter tester combining pH, EC, TDS, and temperature measurement in a single handheld unit. The low-range EC measurement (0–3999 µS/cm) and TDS range (0–2000 ppm) make it well suited for drinking water, aquaponics, hydroponics, and aquaculture applications. All readings are automatically temperature compensated to prevent environment-induced measurement drift. The pH electrode cartridge is easily replaced without tools, and the extendable cloth junction improves response in challenging sample matrices. Simple operation makes this instrument suitable for routine monitoring across a wide range of applications.
