Hanna Instruments
Total Chlorine Checker
Hanna Instruments Total Chlorine Checker
ha_chlor_checkerThe HANNA Checker HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA Checker HC is accurate and affordable.

Check your chlorine levels and know when to replace your carbon filter before chlorine can ruin your TFC membrane.

Checker HC is supplied with sample cuvettes with caps (2), powder reagents for Total Chlorine (6), battery and instructions.
