I-2020 Peracetic Acid

The I-2020 Peracetic Acid Meter is designed for accurately and quickly measuring Peracetic Acid in water levels from 0 - 5.00 ppm. This device uses the DPD Method for testing.  In the USEPA-accepted DPD methodology, free chlorine reacts with DPD to form a pink product. When ammonia or amines are present, some of the chlorine may exist as combined chlorine. Combined chlorine will not interfere with the free chlorine results, provided the readings are taken at one minute. To determine total chlorine (the sum of free and combined), use the A-2500 Activator Solution (potassium iodide) supplied in the kit. Results are expressed as ppm (mg/L) Cl2. The DPD method is also applicable to the direct determination of hypochlorite concentrations in various cleaning preparations and disinfectants prior to their dilution. DPD reacts with hypochlorite ions to form a pink color. Results are expressed as percent (%) NaOCl.

This device has LED display for precise and accurate readout and is easy to use.  Once the I-2020 has been purchased the cost per test is only $1.02.

What's Included:

     -SAM Photometer (I-2020)

     -K-7913 Peracetic Acid Vacu-vials

     -4 AAA batteries for operation

     -Screwdriver for installing/replacing batteries

     -Instruction manual

     -Carrying case to hold device & accessories

How to Use:

Before beginning the test, the I-2020 must be set to zero. Press the power key to turn on the device. The display will show "PAA". Insert the ZERO ampule supplied with the Vacu-vials kit flat end first into the sample cell compartment. Place the light shield over the ZERO ampoule and press the zero/test key. The "PAA" symbol will flash for approximately 8 seconds, then the display will show "0.0.0". Follow the test procedure in the Chlorine Vacu-vials kit also shown below.

1. Add 5 drops of Activator Solution to the empty sample cup.	2. Fill the sample cup to the 25 mL mark with the sample to be tested.
3. Immediately place the Vacu-vial ampoule tip-first into the sample cup. Snap the tip and the ampoule will automatically fill.	4. To mix the ampoule, tilt it from side to side, allowing the bubble to travel from end to end.
5. Dry the ampoule and wait 1 minute for color development.	6. Insert the Vacu-vial ampoule into the photometer, flat end first, and obtain a reading in ppm.
