Applications:Essential for swimming pool chlorine monitoring (residential and commercial), spa and hot tub disinfection verification, drinking water quality testing (EPA compliance), wastewater treatment chlorine residual monitoring, environmental water testing, laboratory analysis, aquaculture water disinfection, and any application requiring accurate free chlorine measurement. Perfect for pool service professionals, water treatment operators, environmental consultants, and water quality laboratories.Compatible Equipment:Milwaukee MW10 Free Chlorine Photometer (required for testing)Why Test Free Chlorine?Free chlorine testing is critical for water safety and disinfection effectiveness. In swimming pools and spas, maintaining proper free chlorine levels (typically 1-3 ppm for pools, 3-5 ppm for spas) ensures effective disinfection while preventing algae growth and waterborne illness. In drinking water, the EPA requires chlorine residual monitoring to ensure safe distribution. In wastewater, chlorine residual testing verifies disinfection before discharge. The MI526-25 powder reagents enable accurate free chlorine monitoring for health, safety, and regulatory compliance.How to Use:
Fill MW10 photometer cuvette with 10 mL water sample to line
Tear open one MI526-25 powder reagent packet
Pour entire contents into cuvette
Cap and shake vigorously to dissolve powder completely
Wait for color development (reaction time per instructions)
Insert cuvette into MW10 Photometer and read free chlorine concentration
Understanding Free Chlorine vs Total Chlorine:Free chlorine is the active, available chlorine that provides disinfection. Total chlorine includes both free chlorine and combined chlorine (chloramines). Free chlorine is the critical measurement for ensuring effective disinfection. The MI526-25 reagents specifically measure free chlorine using the DPD (N,N-diethyl-p-phenylenediamine) method, the industry standard for chlorine testing.Storage & Handling:Store reagent packets in a cool, dry place away from direct sunlight and moisture. Keep packets sealed until ready to use. Do not use damaged or expired packets. Follow all safety precautions on product labeling. Powder reagents offer superior stability compared to liquid reagents when stored properly.Note: Milwaukee MW10 Free Chlorine Photometer sold separately. Reagents are consumable and must be replaced after use. For best results, use fresh reagents and follow all testing procedures carefully.
