HI 98308 (PWT) -An Inexpensive Way to Measure the Purity of Water

Low conductivity read-out on LCD display
Check quality of your distilled or deionized water
Stick shape in a rugged housing
Long battery life
Maintenance-free use
Ideal anywhere distilled and pure water are used.

Pure Water Test (PWT) enables you to check the purity of your distilled or demineralized water in laboratory or industrial environments. PWT is ideally suited for fields such as Printed Circuit Board washing, laundry, steam cleaning, checking car battery water and all areas where distilled, demineralized or pure water is used.

PWT is housed in a completely redesigned and much more durable case which provides excellent protection against harsh industrial environments. The new casing also provides a much larger LCD and is easier to handle with a more ergonomic shape and calibration trimmer on the side. The range of the Pure Water Tester is 0.1 to 99.9 µS/cm, which gives a resistivity read-out as low as 10 Mohm.

The following table shows a typical conversion of the PWT readings:

µS/cm Reading	Resistivity	mg/L of NaCl
99.9	10 Kohms	48
10	100 Kohms	4.3
1	1 Mohms	0.4
0.1	10 Mohms	0.04
