Page 7: Epa Compliance
Epa compliance the 1200 chlorine colorimeter is an epa accepted instrument. Epa accepted means that the instrument meets requirements for colorimeters as found in test procedures that are approved for the national primary drinking water regulations (npdwr) or national pollutant discharge elimination...
Page 8: Chemical Testing
Chemical testing water sampling for chemical analysis taking representative samples the underlying factor to be considered for any type of water sampling is whether or not the sample is truly representative of the source. To properly collect a representative sample: • sample as frequently as possibl...
Page 9: Sampling of Closed System
For dissolved oxygen studies, or for tests requiring small sample sizes, a water sample bottle (lamotte code 1060) will serve as a subsurface or in-depth sampler. This weighted device is lowered to the sampling depth and allowed to rest at this depth for a few minutes. The water percolates into the ...
Page 10: An Introduction to
An introduction to colorimetric analysis most test substances in water are colorless and undetectable to the human eye. To test for their presence we must find a way to “see” them. The lamotte colorimeter can be used to measure any test substance that is itself colored or can be reacted to produce a...
Page 11: Reagent Blank
The 1200 colorimeter has been specially calibrated to read test results directly in parts per million (ppm) of the test factor. The sensitivity of the response has been maximized by using a specific, complementary light source for each test. Reagent blank some tests will provide greater accuracy if ...
Page 12: Sample Dilution Techniques
Sample dilution techniques & volumetric measurements if a test result using the 1200 colorimeter gives an er2 (over range) message, the sample must be diluted. Then the test should be repeated to obtain a reading which is in the concentration range for the test. (note: this is not true for colorimet...
Page 13: Interferences
Interferences lamotte reagent systems are designed to minimize most common interferences. Each individual test discusses interferences unique to that test. Be aware of possible interferences in the water being tested. The reagent systems also contain buffers to adjust the water sample to the ideal p...
Page 14: Overview
General operating information overview the model 1200 colorimeter is a portable, microprocessor controlled, direct reading colorimeter. The microprocessor enables factory programmed calibrations to optimally match non-linear curves. The auto zero feature eliminates the need to dial in the zero manua...

Page 18: Calibration Procedure
Calibration procedure the 1200 has been pre-calibratede. Recalibration of the 1200 by the user is not required. However, a procedure to standardize the calibration (shown below) should be performed to obtain the most accurate readings. 18.
Page 19
U the 1200 can be calibrated with two prepared standards. The concentrations of the standards should be chosen from the low and high ends of the range of the meter. The low standard must be less than 5% of over range. To calibrate the meter with two standards, follow steps 1-11 of the calibration pr...
