- Record calcium hardness reading in mg/L and store remaining reagents in cool, dry location away from direct sunlight
COMPATIBILITY
System Integration
The HI93720-01 reagent kit works exclusively with Hanna photometers designed for calcium hardness testing. This calmagite method is ideal for monitoring RO system feed water, verifying water softener performance, and testing municipal or well water sources. The 0.00 to 2.70 mg/L range covers typical low-hardness applications where precise calcium measurement is critical for equipment protection and process control.
🔧 Store reagent packets in their original sealed packaging until use and check expiration dates regularly. Temperature fluctuations degrade colorimetric reagents, so keep your HI93720-01 kit in a stable environment for consistent test accuracy across all 100 tests.
