9057 Taylor Test Block Chlor (0.25-2.5ppm) LOW/ PH 7.0-8.0

The Taylor 9057 Test Block Chlor is a low-range comparator cell used in Taylor Technologies swimming pool and hot tub test kits (specifically the 2000 series kits like K-2100, K-2105, etc.) to measure chemical concentrations colorimetrically. 

Description and Use:

• Function: It is a clear plastic block with vials for holding water samples and comparing the color change after adding reagents against built-in permanent color standards. This method helps determine the concentration of specific chemicals in the water.
• Tests For: The 9057 low-range block is specifically designed for testing:
• Chlorine (Cl): Ranges from 0.25 to 2.5 parts per million (ppm).
• Bromine (Br): Ranges from 0.5 to 5 parts per million (ppm).
• pH: Ranges from 7.0 to 8.0.
• Compatibility: It is a replacement part for various Taylor Technologies test kits and is typically used with DPD reagents for chlorine/bromine and phenol red for pH testing.
• Design: The comparator block includes fill marks for accurate water volume and a frosted backing to ensure uniform color perception during testing.
