Hanna HI761 Total Chlorine Checker – Ultra Low Range
The Hanna HI761 Total Chlorine Checker is an ultra-low range handheld colorimeter designed to precisely measure total chlorine in water at parts-per-billion (ppb) levels. Ideal for laboratories, environmental monitoring, or any application where trace levels of chlorine must be accurately quantified, the HI761 provides a convenient, digital alternative to traditional chemical test kits, ensuring both simplicity and reliability.
Key Features
Ultra-Low Range Detection: Measures total chlorine from 0 to 500 ppb, suitable for applications requiring high sensitivity.
Digital Precision: Eliminates subjectivity associated with visual color matching by providing a precise digital readout.
EPA-Recognized Method: Utilizes the USEPA method 330.5, based on the DPD colorimetric technique for consistent and reliable results.
User-Friendly Design: Compact and ergonomically shaped for one-handed operation with a single button interface.
Portable & Battery Operated: Ideal for fieldwork and spot-checking with long battery life and automatic shut-off.
