This is a comprehensive test kit good for homeowners with pools and spas, if spas are separate as it includes a bromine test.

Taylor® K-2005 Test Kits are designed for comprehensive water quality analysis in pools and spas by measuring essential parameters to help ensure optimal water balance and sanitizer effectiveness.   This is an 9-way test kit using DPD for Chlorine testing and includes Bromine test for separate spas.

This test kit uses 2 oz reagent bottles.  If you have have lesser frequent testing needs, please select the K-2005 model with lesser expensive 0.75 oz reagent bottles.

High Range test kit

Taylor 2000 Series

Maintaining safe pool/spa water for the public is an important responsibility. Therefore, precise test results are essential when checking the water quality of commercial pools and spas. Taylor 2000 Series is designed for the kind of comprehensive, routine testing performed by service technicians, public and semipublic pool operators, and other professionals. Taylor 2000 Series uses printed color standards to achieve a reliable and accurate color match, making frequent test comparisons even easier.

2000 Series kits feature six different chlorine ( High Range : 0.5-5 ppm, Low Range : 0.25-2.5 ppm), bromine (HR: 1-10 ppm, LR: .5-5 ppm) and pH (7.0 to 8.0) standards

Tests for Chlorine, Bromine, pH, Cyanuric Acid, Hardness, Alkalinity and Acid/Base Demand

Features hard shell case, easy to read comparator and 2 oz reagent bottle sizes.

Features and Benefits:

  • Chlorine 1–10 ppm
  • Bromine 2–20 ppm
  • pH 7.0–8.0
  • Acid & base demand
  • Total alkalinity
  • Calcium hardness

More about Pool Test Kits and Water Analysis Tools

Buyer's Guide: Pool Test Kits and Water Analysis Tools

Tier 1: Daily Maintenance (The Quick Check)

  • Best For: Busy homeowners who need a "Go/No-Go" check before swimming.
  • Look For: [Multi-Way Test Strips] (4-way, 6-way, or 7-way).
  • Expectations: Fast and cheap, but susceptible to moisture damage. Good for spotting trends, less good for precise dosing.

Tier 2: The Troubleshooter (The Standard)

  • Best For: Weekly deep-dives and diagnosing cloudy water or algae.
  • Look For: [Liquid DPD Test Kits] (Look for "DPD" or "FAS-DPD" on the box).
  • Expectations: Requires counting drops and matching colors. Provides the accuracy needed to calculate exact chemical additions.

Tier 3: Precision Tech (The Upgrade)

  • Best For: Data lovers and those who struggle with color matching.
  • Look For: [Digital Water Testers] or [Photometers].
  • Expectations: High upfront cost but eliminates the "guesswork" of comparing colors. often includes apps to track history.

Pool Water Balancers for Proper Chemical Balance

Test kits frequently reveal pH or Alkalinity drift, requiring Balancers (like Soda Ash or Muriatic Acid) to correct the water chemistry.

The Diagnostics of Pool Care
You cannot fix what you cannot measure. A Pool Test Kit is the single most important tool in a homeowner's arsenal because it dictates every chemical decision you make. Without accurate testing, adding chemicals is just guesswork—often leading to cloudy water, skin irritation, or wasted money on unnecessary products.

Understanding the Methods
Test kits primarily come in three forms: Test Strips (fast, dip-and-read), Liquid Drop Kits (highly accurate color matching), and Digital Testers (precise photometers). While strips are excellent for a quick "sanity check" before a swim, a liquid drop kit is essential for diagnosing algae blooms or calculating precise chemical dosages.

Why You Need This
Water balance fluctuates daily due to sunlight, rain, and swimmer load. A quality test kit allows you to catch pH drifts and sanitizer drops before the water turns green, saving you from expensive recovery treatments later.

Common Questions +

Q: Are test strips as accurate as liquid kits?
A: Test strips are accurate enough for daily maintenance but can be difficult to read if you are colorblind or the lighting is poor. Liquid Drop Kits (specifically DPD methods) are generally considered more accurate and are better for troubleshooting specific problems like algae.

Q: What is the difference between OTO and DPD test kits?
A: OTO kits (yellow drops) only measure "Total Chlorine," which includes "dead" chlorine that can't kill bacteria. DPD kits (pink/red color match) measure "Free Chlorine," which is the active sanitizer available to clean the water. We always recommend DPD kits for accurate sanitation.

Q: How often should I test my pool water?
A: In the peak of summer, you should use test strips 2-3 times per week and run a full liquid drop test (including Calcium and Alkalinity) once a week.

Q: Do test kit chemicals expire?
A: Yes. Liquid reagents and test strips typically have a shelf life of 12-24 months. Heat and sunlight degrade them faster. If your drops are discolored or your results seem impossible, it is time to buy a Reagent Refill.

Q: My pH color is hard to match. What should I do?
A: Always read the result against a white background (like a piece of paper) and out of direct sunlight. If you consistently struggle with color matching, consider upgrading to a Digital Water Tester.
