Page 61: Tempco Variation
B. Tempco Variation Most conductivity instruments use an approximation of the temperature characteristics of solutions, perhaps even assuming a constant value. The value for KCl is often quoted simply as 2%/°C. In fact, KCl tempco varies with concentration and temperature in a non-linear fashion. Other solutions have more variation still. -
Page 62: A Chart Of Comparative Error
A KCl correction of 10 (degrees below 25) x 1.9% indicates the solution is reading 19% low. Dividing by (.81) yields 1111 microsiemens for a compensated reading. The difference is 29 out of 1082 = 2.7%. D. A Chart of Comparative Error In the range of 1000 µS, the error using KCl on a solution that should be compensated as NaCl or as 442 , is illustrated in the graph below. -

Page 64: When Does It Make A Lot Of Difference
C. When does it make a lot of difference? First, the accuracy of temperature compensation to 25°C determines the accuracy of any TDS conversion. Assume we have industrial process water to be pretreated by RO. Assume it is 45°C and reads 1500 µS uncompensated. -

Page 66: Ph And Orp/Fc
XXIII. pH and ORP/FC A. pH 1. pH as an Indicator pH is the measurement of Acidity or Alkalinity of an aqueous solution. It is also stated as the Hydrogen Ion activity of a solution. pH measures the effective, not the total, acidity of a solution. A 4% solution of acetic acid (pH 4, vinegar) can be quite palatable, but a 4% solution of sulfuric acid (pH 0) is a violent poison. - Page 67 4. The Myron L Integral pH Sensor ® The sensor in the Ultrameter III (see Figure 34) is a single construction in an easily replaceable package.

5. Sources of Error The basics are presented in pH and ORP/FC , pg. 62. a. Reference Junction The most common sensor problem will be a clogged junction because a sensor was allowed to dry out.
