What to do if the Industrial Test Systems Pool eXact EZ Test Equipment shows 'HI' on the LCD Display while reading?
If the Industrial Test Systems Test Equipment displays 'HI' on the LCD while reading, it means the result is above the detection level. To address this, re-run the test to verify the result.
Why does the Industrial Test Systems Pool eXact EZ Test Equipment show 'LO' on LCD Display while zeroing?
If the Industrial Test Systems Test Equipment displays 'LO' on the LCD while zeroing, several factors could be responsible. It could be due to low batteries, which requires replacing them. Another potential cause is a dirty cell; in this case, clean the cell. A cloudy sample might also trigger this error, so dilute the sample or use a sieve. If none of these resolves the issue, a bad LED might be the cause, and you should contact ITS.
What does it mean when the Industrial Test Systems Test Equipment shows 'LO' on LCD Display while reading?
If the Industrial Test Systems Test Equipment displays 'LO' on the LCD while reading, it indicates that the result is below the detection level. To confirm, re-run the test.
What to do if the Industrial Test Systems Pool eXact EZ 'LO' flashes on LCD Display, then Err?
If the Industrial Test Systems Test Equipment's LCD Display flashes 'LO' and then shows 'Err', it usually means the test procedure for Combined Chlorine was not correctly followed. Carefully re-read the test procedure and ensure you follow the directions precisely.
How to fix a dim screen or no response from Industrial Test Systems Test Equipment?
If the Industrial Test Systems Test Equipment screen is dim or the meter isn't responding, the most likely cause is a low battery. Try replacing the batteries.

The Pool eXact® EZ Photometer is an advanced photometric system designed for precise and easy maintenance of pool water quality, delivering lab-quality results directly poolside. This device is engineered for digital accuracy, ensuring better pool care through reliable water testing. It is a waterproof (IP-67 rated) handheld meter with a built-in sample cell, enhancing its usability and durability.
The primary function of the Pool eXact® EZ Photometer is to measure various parameters of pool water using a photometric method. It utilizes eXact® Strip Micro reagents to perform tests for Free Chlorine (DPD-1), Combined/Total Chlorine (DPD-3), pH, Calcium Hardness, Total Alkalinity, and Cyanuric Acid. The meter works by detecting color changes in the water sample after the addition of a reagent strip, converting these changes into a digital reading displayed on its LCD screen.
The device operates on a simple "Fill, Dip, Read" principle. To begin a test, the user fills the built-in sample cell with the water sample. After selecting the desired test parameter using the MENU button, a reagent strip specific to that test is dipped into the sample cell. The meter then initiates a countdown timer, during which the strip is gently moved back and forth in the sample. Once the countdown is complete, the meter measures the sample and displays the result in parts per million (ppm) or pH.
For Combined/Total Chlorine tests, a continuation method is used. After running the Free Chlorine (DPD-1) test, the sample is retained in the cell, and a DPD-3 strip is added to measure Combined Chlorine. If Total Chlorine is required, the READ button is pressed again after the Combined Chlorine result is displayed.
The photometer is equipped with a ZERO/ON button that serves multiple purposes: it turns the meter on, initiates the zeroing process to establish a baseline for water testing, and is used in conjunction with dipping the strip to start the countdown timer. The READ button starts the test timer and displays the final result. The MENU button allows users to cycle through different test menus and, when held down, can retrieve stored test results.
The meter incorporates state-of-the-art technology, including a long-life LED and a photo cell, which contribute to its fixed calibrations remaining valid for the life of the meter. The software algorithms are designed to correlate with AWWA, US EPA, DIN, and ISO reference test methods for chlorine, ensuring high accuracy and compliance with health department requirements for reporting Free and Total Chlorine.
The Pool eXact® EZ Photometer is designed for user-friendliness and convenience. Its compact, handheld design makes it ideal for poolside use. The built-in plastic 4ml sample cell simplifies the process of collecting water samples, eliminating the need for external vials. A cell cover is provided to protect the cell and ensure accurate readings in bright light conditions, as well as for mixing samples.
The LCD display clearly shows test names, results, and units (ppm, pH, %T). Indicators for low battery and result units are also present. The meter has an automatic shutdown timer that activates after 5 minutes of inactivity to conserve battery life.
A significant feature is its internal memory, capable of storing up to 20 results per test menu, totaling 100 results across all menus. Users can retrieve these stored results by pressing and holding the MENU key, allowing them to review the last 20 readings in sequence, from the most recent to the oldest.
For optimal accuracy, the manual provides specific usage tips:
Maintaining the Pool eXact® EZ Photometer is straightforward, focusing on ensuring its longevity and accuracy. The device requires four AAA batteries for operation, which are installed in the base. The battery compartment is IP67 rated waterproof, protecting against water ingress. The manual provides clear instructions for battery installation, including the use of a Phillips head screwdriver to remove the base screw. The meter powers on automatically once batteries are correctly installed.
Cleaning the sample cell is a crucial maintenance step. After each test, the sample cell should be rinsed immediately with water. The photometer comes with a cleaning brush specifically designed to thoroughly scrub the sample cell. For more stubborn residue, dish soap or distilled white vinegar can be used, but solvents like acetone should never be used as they can damage the cell. Regular cleaning helps prevent residue buildup that could affect test accuracy.
For prolonged storage, it is recommended to remove the batteries to prevent corrosion. The meter and test materials should be stored away from direct sunlight and chemical storage areas to protect them from degradation. Minimizing exposure to heat above 90°F (32°C) is also advised for both the meter and reagents.
When reinstalling batteries, users are reminded to verify that the O-ring is properly attached to the screw before tightening, ensuring the waterproof seal remains intact. The built-in sample cell, made of transparent plastic, is designed to withstand over 20,000 readings, and minor scratches will not compromise the accuracy of results due to its fixed position.
Troubleshooting guidance is provided for common issues such as a dim screen, "LO" or "HI" readings on the LCD, or "Err" messages, offering solutions like replacing batteries, cleaning the cell, diluting samples, or re-reading test procedures. This comprehensive approach to maintenance ensures the photometer remains a reliable tool for pool water analysis.
