eXact® Strip Micro CL (DPD-1, DPD-3, DPD-4) Interferences

Interfering Substance

Interfering Levels & Treatments

Acidity If sample has acidity above 150mg/L CaCO3 test may not develop

full color. Neutralize to pH 6.0 to 7.0 with 0.5N Sodium hydroxide.

Alkalinity If sample has alkalinity above 200mg/L CaCO3 test may not

develop full color. Neutralize to pH 6.0 to 7.0 with 0.5N Sulfuric acid.

Color similar to other oxidizer reaction at all levels.

Chlorine, Cl

Color similar to other oxidizer reaction at all levels.

Chlorine Dioxide, ClO

Color similar to other oxidizer reaction at all levels.

Copper, Cu

Color development is reduced above 10 ppm (mg/L).

Iodine, I

ACRYLIC CALIBRATION KEY

READ RESULT & RECORD

Result is displayed on the Pool eXact® EZ. Record value below. For additional tests, repeat steps 4-6.

Expect the result to be within

0.15 units from previous calibration. If variation is greater, please re-check your ZERO procedure (steps 3-4 on page 10) and be sure to use clean water (deionized or distilled if necessary).

The Acrylic Calibration Key is a tool for verifying the calibration of your Pool eXact® EZ Photometer compared to its original factory settings. Run this test immediately upon receipt and record value for future reference. Follow steps 1-4 on page 10 (do not use cap during ZERO). Then, follow the remaining steps below.

FOR BEST ACCURACY

The Pool eXact® EZ photometer has a 5 minute auto-shutoff timer.

Each test menu can store 20 results. To retrieve the stored results, go to the desired test using the MENU key. When the desired test is displayed, press and hold down the MENU key. Continue holding down the MENU key to scroll the stored results for that test, starting with the most recent result. The meter will display, from memory, the last 20 readings in sequence beginning with -20, which is the latest result, followed by -19, which is the 2nd latest result, etc; and ﬁ nally -01, which is the oldest result retained. Only the last 20 readings are stored in each menu. This meter is able to store 160 results in memory (20 in each menu).

Before testing rinse CELL and clean with brush thoroughly. (Rinsing minimizes the potential for cross-contamination from a previous test.)

Always ﬁ ll the cell to capacity (4mL); be careful not to splash liquid over the side.

When testing pH, it is recommended to run the pH test prior to running Chlorine. If you choose to run the pH after Chlorine, ensure you thoroughly clean the cell with water and the brush provided. Test immediately after ﬁ lling the cell with the water sample.

Due to the strip slitting process, you may ﬁ nd one or two strips that are noticeably smaller or larger in width than the normal strips in the bottle. These should be discarded. Using these strips may give unreliable results.

Meter is not compatible for use with powder pillows, tablets, or liquids from other manufacturers.

Dip strip for entire countdown.

Each eXact® Strip Micro is valid for ONLY one test. Discard strip after use.

Dry the outside of the meter and inside the mixing cap before storage to prevent corrosion.

Remove batteries before storing for prolonged periods.

Store the meter and test materials out of direct sunlight and away from chemical storage areas.

Minimize exposure of meter and test reagents to heat above 90°F (32°C).

When installing batteries, verify the O-ring is still attached to the screw before tightening.

Even if all pads are not immersed in water, DO NOT BEND THE STRIP. Make sure the strip touches the bottom of the CELL while dipping the strip for 20 seconds.

To ensure lab quality results, it is recommended to clean the cell with the brush provided after every test. Use Distilled White Vinegar to clean the cell after testing for Phosphate to remove reagent deposits from the cell wall.

Manufacturing quality products since 1989

POOL EXACT® EZ ACCURACY

All tests have been calibrated using certiﬁ ed reference standards and analytical spectrophotometric methods. The Pool eXact

EZ has been factory calibrated and will stay valid because of its exceptional quality. We are so conﬁ dent in the Pool eXact

EZ,

we offer an industry leading 2-year warranty.

We built the Pool eXact

EZ to be easy, accurate and environmentally friendly. We have achieved this by utilizing our patented eXact

Strip Micro Technology, which uses 60% less water and chemistry than alternative methods. Instead of using a 10mL water sample, eXact

Strip Micro uses a 4mL water sample. The accuracy of the meter is maintained by designing the sample cell with an 11mm path-length.

Page 25

exactmeters.com

BUILT IN SAMPLE CELL

The built-in sample cell is made of transparent plastic; the sturdy cell design will last for over 20,000 readings. Our studies have shown that scratches on the cell will not compromise the accuracy of your results because of the cell’s ﬁ xed position.

WARRANTY (2 YEARS)

Registration of your Pool eXact® EZ photometer must be received within 30 days from date of purchase to activate the warranty. Registration is available over the phone (+1-803-329-9712 Ext. 0) or online at

(Personal data is kept conﬁ dential). The Pool

eXact

EZ photometer is warranted to be free from defects in materials and workmanship for a period of two (2) years from the date of purchase by the customer. ITS will repair or replace, at its discretion, product which is deemed to be faulty due to manufacturing defect. Warranty does not cover product damage caused by abuse (such as crushing a tablet in the cell), battery corrosion damage, or improper use. If the meter is faulty or otherwise defective contact ITS by phone (+1-803329-9712 Ext. 0) or email ([email protected]) to describe the problem and obtain a return authorization form before returning the photometer to ITS. Damage caused by improper packing of the photometer for return shipment to ITS will not be covered by the warranty. Customer is responsible for shipping charges to ITS. ITS pays postage when photometer is returned to customer. A maximum processing fee of $75 will be charged for repair or replacement of non-registered photometers and damages not covered by this warranty. The repair or replacement of the photometer will not extend or renew the period of guarantee. This warranty does not affect your statutory rights. The warranty is not transferable.

COMPLIANCE TESTING

This DPD test system for Chlorine is accepted for reporting by most health departments because the tests are USEPA (DIN Standard 38 408 G4/G5, ISO 7393/2) accepted for testing requirements for Free Chlorine and Total Chlorine.

The compliance requirement is a photometer wavelength to measure between 490 and 530nm. The Pool eXact® EZ smart photometer uses a 525nm wavelength and 11 mm path-length. The eXact® Strip Micro CL (DPD-1) use the same reagents and proportions, and the resulting solution pH is maintained between

6.2 and 6.5 as speciﬁ ed by AWWA method 4500-Cl G/ClO2-D. The USEPA does not “approve” commercial DPD delivery systems. The eXact® Strip Micro CL (DPD-1) for Free Chlorine, and the eXact® Strip Micro CL (DPD-3) for Combined Chlorine, and the eXact® Strip Micro CL (DPD-4) for Total Chlo rine meet your reportable testing requirements because the eXact® Strip Micro strips deliver the same chemicals in identical proportions. Consult with your local health department for ofﬁ cial regulations.

MODEL AQUATIC HEALTH CODE

AND NSF/ANSI 50 CERTIFICATION

The Model Aquatic Health Code (MAHC) is a set of guidelines published by the Centers for Disease Control and Prevention (CDC). This document brings together the latest knowledge based on science and best practices to help state and local government ofﬁ cials develop and update pool codes. They may use the code in whole, choose to use parts, or modify to ﬁ t their needs. Use of the MAHC is intended to save time and resources spent individually developing and updating codes across the country, while giving agencies the beneﬁ t of the latest science and best practices to help keep pools fun, safe, and healthy.

The MAHC requires NSF/ANSI 50 certiﬁ cation of water quality testing devices (WQTD) used in recreational facilities such as public swimming pools, interactive fountains, and Waterparks. Third-party certiﬁ cation to NSF/ANSI 50 allows manufacturers to make veriﬁ ed claims regarding the performance, accuracy and operating range of their WQTD. The performance testing of a WQTD involves accuracy and repeatability testing on two different lots of new production. Unlike most NSF/ANSI 50 certiﬁ cations, WQTDs require follow-up testing of the product at the end of the manufacturer’s speciﬁ ed shelf life. Certiﬁ ed products are given an accuracy rating to one of three levels: L1, L2 or L3, with L1 being the highest accuracy rating.
