Page 4: General Information
24 hours a day from the Poison Control Center listed in the front of the phone book. Be prepared to supply the name and four digit LaMotte code number found on the container label or at the top of the MSDS. LaMotte reagents are registered with POISONDEX, a computerized poison control information system available to all local poison control centers. -

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 Systems (NPDES) compliance monitoring programs. -
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 possible. -
Page 9: Filtration
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 sample chamber displacing the air which bubbles to the surface. -
Page 10: 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 color. -
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 a reagent blank is determined, to compensate for any color or turbidity resulting from the reagents themselves. -
Page 12: Sample Dilution Techniques & Volumetric Measurement
SAMPLE DILUTION TECHNIQUES & VOLUMETRIC MEASUREMENTS If a test result using the 1200 Colorimeter gives an (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 colorimetric determination of pH.) -
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 pH for the reaction. -
Page 14: General Operating Information Overview
This will not affect the user calibration and the meter will not have to be re-zeroed. The calibration and the last zero reading will be stored in memory. The 1200 is supplied with a 9 volt alkaline battery. An optional AC power adapter is available. -

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. - Page 19 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 procedure for one reacted sample.

RS232 PORT The 1200 Colorimeter may be interfaced with any IBM compatible computer using an Interface cable (Code 27359-04). The meter may also be interfaced with an RS-232 serial printer, using an appropriate cable and setting the printer configuration to the output below. -
Page 25: Replacing The Battery
MAINTENANCE REPLACING THE BATTERY The LaMotte 1200 uses a standard 9-volt alkaline battery that is available worldwide. The battery compartment is located on the bottom of the case. To replace the battery: 1. Open the battery compartment lid. 2. Remove the battery and disconnect the battery from the polarized plug. - Page 26 5.00 • RM626728...
