Main Product Categories
Drinking & Well Water Analysis Kits
These flagship 16-in-1 and 19-in-1 multi-panel kits come packed with up to 125 strips per vial to aggressively screen your everyday water for critical hazards like lead, copper, iron, nitrates, and erratic pH levels.
Pool, Spa, & Hot Tub Testing Strips
Engineered specifically for recreational water care, this specialized variant line zeros in on precise sanitization chemistry by tracking free chlorine, bromine, total alkalinity, and cyanuric acid stabilizers.
Biological Contamination Add-ons
Providing an extra layer of defense against invisible threats, these comprehensive bundles pair standard chemical test strips with specialized 48-hour liquid incubation vials to accurately detect the presence of Coliform and E. coli.
Customer Reviews
David Miller
“Living out on a rural property means our well water is always at the mercy of nearby agricultural runoff, so I bought the 16-in-1 drinking water kit to stay on top of things. The testing process was incredibly straightforward, and within 30 seconds, the nitrate and iron pads flagged an elevation that prompted me to change out my whole-house pre-filters earlier than planned. While matching the colors requires a steady eye under good lighting, having over a hundred strips in one bottle gives me the freedom to test our taps every single month without breaking the bank.”
Sarah Jenkins
“I have been using the pool and spa strips all summer for our backyard hot tub, and they have completely streamlined my maintenance routine. Instead of messing around with complicated liquid drop kits where I am always second-guessing the chemical drops, I just dip these strips for a couple of seconds and instantly know exactly how much chlorine and stabilizer to add. The airtight bottle keeps the remaining strips completely dry, meaning I don’t have to worry about humidity ruining the reagents before the pool season ends.”
Marcus Vance
“After moving into an older home with questionable copper piping, I wanted a fast way to check for heavy metals, which led me to the complete kit featuring the biological add-on. The standard chemical strips gave me immediate peace of mind regarding our tap’s pH and copper thresholds, but the real value was the 48-hour E. coli incubation vial. Following the simple instructions, I left the sample on my counter for two days, and watching it remain a solid negative color gave my family absolute confidence in our daily drinking water.”
TESPERT FAQ
Why did the colors on my test strip bleed into each other?
This happens when the strip is held vertically or shaken aggressively right after being pulled out of the water. Liquid from one highly reactive chemical pad can run down into an adjacent pad, causing chemical cross-contamination. To fix this, always draw the strip straight out of the water sample and hold it perfectly flat and horizontal like a level until your incubation countdown is complete.
How long do I actually have to read the results before they become invalid?
You must compare the strip colors against the bottle chart between 15 and 60 seconds after immersion, depending on the exact parameter. If you wait longer than 2 minutes, ambient oxygen reacts with the exposed reagent chemical pads, triggering natural oxidation that permanently distorts the color blocks and creates false metrics.
Why do some of my test pads match the baseline zero color perfectly?
If your water source is balanced and free of pollutants, the pads measuring elements like Lead, Nitrates, or Copper will logically match the baseline “level 0” square on the packaging. To verify if a batch of strips is working properly, you can run a diagnostic test on a known source—such as checking a commercial sports drink to see the pH pad react intensely or testing outdoor pool water to view the chlorine pad turn bright green or blue.
What is the ideal environment to read the color blocks accurately?
Strips should always be evaluated under normal, clear daylight or well-lit, neutral white indoor lighting. Avoid reading the results under highly colored ambient light, dim shadows, or direct, intense sunlight, as these conditions significantly alter how the subtle gradient shades appear to the human eye.
Why did my bacteria incubation test bag change color after the 48-hour mark?
The biological screening vials or bags are formulated to yield an accurate positive or negative reading strictly within a 24-to-48-hour incubation window at room temperature. Once you pass the 72-hour threshold, the organic nutrients inside the testing media will naturally degrade and shift colors on their own, making any late readings entirely invalid.
Can these strips replace a certified professional laboratory water analysis?
No, these kits are designed exclusively as semi-quantitative, rapid screening tools to help you identify sudden baseline spikes or check if an existing home filtration system is operational. They display findings in broad color ranges rather than specific decimal percentages, meaning any positive indicator for hazardous heavy metals like Lead should always be cross-verified by an EPA-certified laboratory.
