Exact 486629 Micro Calcium Hardness Strip for Photometers | Precise Water Hardness Testing

Overview

The Exact 486629 Micro Calcium Hardness Strip is engineered for use with eXact Photometers. Built around a patented reagent delivery system from Industrial Test Systems, it releases a precise amount of reagent into the water sample when the strip is dipped into a photometer cell. The resulting color change or turbidity is measured by the eXact device, offering fast, repeatable results that support informed water management decisions. This kit arrives as a bulk bottle containing 50 individual tests, designed for both technical setups and everyday testing at home or in small facilities.

What’s in the box

• Bulk bottle with 50 calcium hardness tests for water testing
• Reagent compatible with multiple eXact models, enabling flexible use across devices
• Reference for the visual method is Pool Check 3 in 1, part number 481335
• Made in the USA

Compatibility and ranges

Designed to work with the eXact photometer ecosystem, including:

• eXact iDip: 30–720 ppm
• eXact Micro 20 W with Bluetooth SMART: 20–400 ppm
• eXact Micro 10: 20–300 ppm
• eXact Pool EZ: 21–720 ppm
• eXact Spa EZ: 19–550 ppm

How to use

• Dip the strip into a photometer cell to release the exact reagent amount.
• Place the cell in the eXact device and initiate the reading as directed by your model’s user guide.
• Interpret the color or turbidity change on the photometer’s display to estimate calcium hardness.

Why this matters

Calcium hardness is a common parameter in water maintenance. While no single test guarantees a perfect outcome, precise, reproducible readings can help you monitor water quality and adjust balance levels with greater confidence. The Exact Micro Calcium Hardness Strip is designed to deliver consistent results across diverse environments, from residential pools and spas to small commercial facilities. The USA-made kit benefits from a standardized reagent system and a bulk format that can fit into regular testing routines without frequent reordering.
