Model 1200 Single Test Colorimeter The Model 1200 Series of single test, direct reading colorimeters incorporates design advances that enhance reliability, improve accuracy, and simplify the calibration process, all in a portable, hand-held package.

Field & Lab Use: An optional AC adapter (Order Code 1754) is available to save battery life when in the laboratory. Large Display: The large 3 digit display presents measurements in absorbance, and indicates low battery warnings. RS-232 Interface: An RS-232 port is provided to interface with a datalogger or computer. Optional cable available, Order Code 1772. European CE Mark: The 1200 has been independently tested and has earned the European CE Mark of compliance for electromagnetic compatibility and safety. EPA Compliant: Employing the proper wavelength and the DPD test method, the 1200 Chlorine Colorimeter Kit meets or exceeds EPA design specifications for NPDWR and NPDES chlorine monitoring programs (EPA 330.5 and Standard Method 4511-Cl-G). 0-4 ppm Chlorine: No need to select a low or high range. The 1200 covers the entire critical chlorine range of 0-4 ppm with a 0.05 sensitivity. A Great Value: Complete, economical package! The 1200 Chlorine Colorimeter Kit comes with enough tablets for 100 tests or liquid reagents for 140 tests, six sample vials with screw caps, instruction manual, and sturdy carrying case. * Water Resistant Design: Designed with excessive exposure to moisture in mind, the 1200 colorimeters deliver trouble-free performance in the field and lab. Improved Accuracy: The microprocessor enables the factory programmed calibrations to optimally match non-linear curves. Auto-Zero: Simply insert the sample blank and press the zero key. No more dialing in the zero. Hinged Light Cover: Flip-top lid over sample chamber prevents any stray light, especially in the field, and avoids misplacing separate light caps.   Specifications Instrument Type: Single wavelength, direct-reading colorimeter Display: 3-1/2 digit LCD Photometric Precision: ±0.001 Absorbance Unit Detector: Silicon Photodiode Sample Chamber: Accept 25mm flat-bottomed glass vials with screw caps Light Source: LED Interface: RS-232 serial interface, 8 pin mDIN, 9600b, 8 data bits, 1 stop bit, no parity Power: Battery Operation: Alkaline 9-volt DC battery Line Operation: 120V/60Hz, 220V/50Hz with adapter Size (LxWxH): 15 x 8 x 5.5 cm; 6 x 3-1/4 x 2-1/2 inches Test Factor Code Model Range (ppm) Detection Limit Test Method (# of Reagents) Ammonia Nitrogen 3680-01 DC1200-NH 0-5.0 0.05 Nessler (2) Bromine 3672-01 DC1200-BR 0-7.0 0.05 DPD Tablets (1) Chlorine (Free & Total) 3670-01 DC1200-CL 0-4.0 0.05 DPD Tablets (2) Chlorine (Free & Total) 3670-01-LI DC1200-CL-LI 0-4.0 0.05 DPD Liquid (3) Chlorine Dioxide 3671-01 DC1200-CLO 0-7.0 0.05 DPD with Glycine Solution (2) Chlorine Dioxide 3671-01-LI DC1200-CLO-LI 0-7.0 0.05 DPD Liquid (3) Copper 3673-01 DC1200-CO 0-6.0 0.03 Diethyldithiocarbamate (1) Fluoride 3674-01 DC1200-FL 0-2.0 0.028 Alizarin-Zirconyl (2) Iron 3681-01 DC1200-FE 0-4.0 0.25 1-10 Phenanthroline (2) Manganese 3682-01 DC1200-MN 0-0.7 0.02 PAN (3) Molybdenum 3676-01 DC1200-MO 0-30 0.5 Thioglycolate (3) Nitrate Nitrogen 3677-01 DC1200-NA 0-3.0 0.05 Cadmium Reduction (2) Ozone 3678-01 DC1200-OZ 0-0.4 0.04 Indigo Blue (3) Ozone (without other oxidizers) 3598 DC1200- OZ-DPD 0-3 0.03 DPD Liquid Phosphate 3679-01 DC1200-PLR 0-3.0 0.07 Ascorbic Acid (2) Sulfate 3683-01 DC1200-SU 0-100 1.0 Barium Chloride (1) Chlorine Standards for Model 1200 For use with the 1200 series of chlorine colorimeters. Secondary standards provide a fast way to check calibration without the burden of making primary standards. Based on Standard Methods for the Examination of Water and Wastewater, 20th ed., 1998, the operator can calibrate a colorimeter using a permanganate primary standard or a chlorine primary standard. Once the meter is calibrated using the primary standard, the operator can insert secondary standards periodically to evaluate the calibration of the instrument. Secondary standard kit contains a blank and 3 standards for low, mid-range, and high chlorine calibrations. Packaged in a small plastic case with Certificate of Analysis stating range of each standard.
