The Hanna HI97106 Chemical Oxygen Demand (COD) Portable Photometer is a rugged, lab-grade instrument designed for field or bench testing of water and wastewater. Here's a complete overview:
Waterproof & durable: Sealed optical system within an IP67-rated floating case—ideal for outdoor conditions
High-precision optics: Dual LEDs (420 /nm for low range; 610 /nm for mid/high/ultra-high) with narrow-band (±1 /nm) interference filters and silicon photocell detector
Consistent readings: Positive-lock vial system ensures exact positioning for repeatability
User guidance: Integrated tutorial walks through sample prep and reagent use
Performance verification: CAL Check™ function with NIST-traceable cuvettes confirms instrument accuracy on-site
Auto data logging: Stores up to 200 measurements, with auto-off after inactivity to save power
