Chlorine Portable Photometer - HI97790 - Hanna Instruments Australia

Description

The HI97790 meter measures free and total chlorine in water samples from 0.00 to 5.00 mg/L (ppm). The method is an adaptation of the Standard Methods, 4500‐Cl G, DPD Colorimetric Method. Chlorine is a widely used disinfectant in the treatment of drinking water, wastewater, and swimming pools.

Main Features:

Only one sample needed for successive free and total chlorine measurements.
– Take a ZERO reading
– Add required reagents for Free Chlorine testing
– Read Free Chlorine levels
– Add required reagents for Total Chlorine testing
– Read Total Chlorine levels
Ideal for regulatory compliance in areas requiring successive sample measurements.
Easy-to-use and cost effective while maintaining high accuracy
Advanced LED optical system
– Innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.
– LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.
– The optical system is sealed from outside dust, dirt and water.
– An exclusive positive‐locking system ensures the cuvettes are placed into the holder in the same position every time.
CAL Check™
– Validate instrument performance at any time using CAL Check cuvettes made with NIST traceable standards. The CAL Check screen guides the user step-by-step through the validation process and user calibration.
On-screen tutorial mode with animations
– Guides users step-by-step through the measurement process
Waterproof and floating IP67 case
Unit of measure is displayed along with reading
Built-in timer
– Built-in reaction timer that ensures consistency between tests.
Error messages on display
– Alerts to problems including no cap, high zero, and standard too low
GLP data:
– Displays the last calibration date.
Auto data log and recall up to 50 individual measurements
Battery status indicator
Auto-shut off
