Instruction Manual HI 9033 • HI 9034 Waterproof Multi-Range EC and TDS Meters for Field Applications
The Hanna Instruments HI 9033 and HI 9034 are waterproof multi-range meters designed for extended use in wet, humid, dusty, and muddy conditions. They utilize four-ring potentiometric technology to provide higher accuracy than the common amperometric method. The HI 9033 measures conductivity in four ranges, while the HI 9034 measures total dissolved solids (TDS) in three ranges. Both instruments feature automatic temperature compensation (ATC) and a Battery Error Prevention System (BEPS).
