HI 93724

Cyanuric A. & pH

The HI 93724 meter measures cyanuric acid and pH content in water

and wastewater in the following ranges: 0 to 80 mg/L for Cyanuric

Acid (CYS) and 5.9 to 8.5 for pH.

SPECIFICATIONS

Range CYS 0 to 80 mg/L

pH 5.9 to 8.5

Resolution CYS 1 mg/L

pH 0.1

Accuracy CYS ±1 mg/L ±15% of reading

pH ±0.1

Typical EMC CYS ±1 mg/L

Deviation pH ±0.1

Light Source Light Emitting Diode @ 555 nm

Method For pH, Phenol Red method. The reaction with

reagent causes a red tint in the sample.

For cyanuric acid, adaptation of the turbidimet-

ric method. The reaction between cyanuric acid

and the reagent causes a white suspension in

the sample.

• Fill one graduated mixing cylinder up to the

25 mL mark with deionized water.

• Add the content of one packet of HI 93746 TPTZ reagent, close

the cylinder and agitate for 30 seconds. This is the blank.

• Fill a cuvet with 10 mL of the blank up

to the mark and let it sit for 3 minutes.

• Replace the cap, insert the blank into

the holder and make sure that the notch

on the cap is positioned securely into

the groove.

• Press ZERO and "SIP" will appear on the display.

• Wait for a few seconds and the display will

show "-0.0-". Now the meter is zeroed and

ready for measurement.

• Fill one graduated mixing cylinder up to the

25 mL mark with the sample.

• Add the content of one packet of HI 93746 TPTZ reagent, close

the cylinder and agitate for 30 seconds.
