Exact Industrial Test Systems 486637 DPD-1 Micro Free Chlorine Strip for Photometers

Description

Product Overview

The Exact Industrial Test Systems 486637 DPD-1 Micro Free Chlorine Strip is a specialized reagent designed exclusively for use with eXact photometers, providing a reliable and straightforward method to measure free chlorine levels in a variety of water environments. Each strip is formulated with a high‑purity DPD (N,N‑diethyl‑p‑phenylenediamine) reagent that reacts instantly with free chlorine, producing a distinct color change that can be accurately quantified by the compatible photometer. The product is packaged in a bulk bottle containing 100 individual test strips, each measuring approximately 8.25 x 4 x 1.63 inches and weighing 1.41 ounces, making it convenient for both professional pool maintenance technicians and diligent homeowners. Manufactured in the United States, the strips benefit from stringent quality control processes that ensure uniform reagent distribution, consistent color development, and long‑term stability under typical storage conditions. The DPD‑1 formulation covers a broad detection range, from as low as 0.01 ppm up to 12.0 ppm, depending on the specific eXact photometer model, allowing users to monitor chlorine levels across a wide spectrum of pool, spa, and hot‑tub applications. The product is discontinued by the manufacturer, but existing inventory remains a valuable resource for those who require a trusted, proven testing solution. With a best‑seller rank of #78 in Swimming Pool Test Strips and a customer rating of 4.7 out of 5 stars based on 57 reviews, the strip has demonstrated consistent satisfaction among users who value accuracy, ease of use, and dependable performance.

Usage

These free chlorine test strips are intended for routine water quality monitoring in residential and commercial pool settings, hot tubs, spas, and any recirculating water system where chlorine is used as a primary disinfectant. To use, a small water sample is collected in a clean container, and a single strip is immersed for the recommended time, typically a few seconds, allowing the DPD reagent to react with any free chlorine present. The resulting color is then read by an eXact photometer, which automatically calculates the chlorine concentration based on the intensity of the hue. This method eliminates the need for subjective visual comparison, reducing human error and providing repeatable results. The strips are also suitable for field technicians who need to perform on‑site testing at multiple locations, as the compact packaging and straightforward procedure enable rapid assessments without the need for bulky equipment. Because the strips are compatible with a range of eXact photometer models—including the iDip, Micro 20 BT, Micro 7+, Micro 10, Pool/Spa/Chlorine EZ, and EcoCheck—users can select the appropriate device for their specific testing requirements, ensuring flexibility and scalability across different operational contexts. Proper storage in a cool, dry place away from direct sunlight helps maintain reagent integrity, extending the usable life of the strips throughout the season.

FAQ

What types of water can I test with this strip?

The strip is designed for any water system that uses free chlorine as a disinfectant, including residential swimming pools, commercial pools, hot tubs, spas, and recirculating water features. It works equally well with chlorinated water in indoor and outdoor environments.

How do I store the test strips to maintain their accuracy?

Store the strips in a cool, dry place away from direct sunlight and moisture. Keep the bottle tightly sealed when not in use. Proper storage helps preserve the reagent’s stability, ensuring reliable results throughout the product’s shelf life.

Can I use these strips with visual methods instead of a photometer?

While the strips are optimized for use with eXact photometers, they can also be used with visual comparison kits such as the SenSafe Free Chlorine Water Check (part numbers 481026 or 481126). However, using a photometer provides more accurate, objective readings and eliminates the subjectivity of visual interpretation.

What should I do if I get an unexpected reading?

If a result seems unusually high or low, first verify that the water sample was collected correctly and that the strip was fully immersed for the recommended time. Check the photometer’s calibration and ensure the device’s sensor is clean. If the issue persists, contact our support team with the batch number and details of the test; we can provide troubleshooting steps or arrange a replacement if a defect is identified.

Is this product still available despite being discontinued?

Yes, existing inventory remains available for purchase. While the manufacturer has discontinued production, the current stock continues to meet quality standards, and we maintain sufficient supply to fulfill customer orders. We also monitor inventory levels closely to ensure you can obtain the strips when needed.
