Applications:Essential for boiler water treatment monitoring (preventing scale and corrosion), cooling tower water quality control, industrial water treatment programs, power plant water chemistry, steam generation systems, high-purity water production, environmental water testing, laboratory analysis, and any application requiring accurate high-range silica measurement. Perfect for water treatment professionals monitoring silica levels to prevent equipment damage, scaling, and efficiency losses.Compatible Equipment:Hanna HI770 Silica High Range Checker HC (required for testing)Why Test Silica Levels?Silica monitoring is critical in industrial water systems. In boiler water, excessive silica causes hard, glassy scale deposits on heat transfer surfaces, reducing efficiency and potentially causing equipment failure. In cooling towers, silica can precipitate and foul heat exchangers. In steam generation, silica can carry over into steam and deposit on turbine blades. The HI770-25 high range reagents enable accurate monitoring of elevated silica levels to prevent these costly problems.How to Use:
Fill HI770 Checker HC cuvette with 10 mL water sample to line
Tear open one HI770-25 reagent packet (Reagent A)
Pour entire contents into cuvette
Cap and shake to mix thoroughly
Add second reagent packet (Reagent B) if required by method
Wait for color development (reaction time per instructions)
Insert cuvette into HI770 Checker HC and read silica concentration
Storage & Handling:Store reagent packets in a cool, dry place away from direct sunlight. Keep packets sealed until ready to use. Do not use damaged or expired packets. Follow all safety precautions on product labeling.Note: HI770 Silica High Range Checker HC sold separately. Reagents are consumable and must be replaced after use. For best results, use fresh reagents and follow all testing procedures carefully.
