Choose from Three Models
Depending on the testing needs, we select an ATO-CM-SC-10, ATO-CM-NR110, and ATO-CM-NH300 Colorimeter, preprogrammed to test for at least 20, 50, or 90 parameters, respectively. All three models include the same convenient features: auto-wavelength selection, data logging capabilities, and user-generated calibrations.
These durable, hand-held, filter photometers are designed specifically for the rigors of on-site testing, with rugged components and waterproof, dustproof, chemical-resistant housings. The ATO-CM-NH300 of model Colorimeters offers simple, push-button program selection and step-by-step prompts that guide users through the testing procedure.
Advanced Features Add Value
- Easy-to-use software offers push-button method selection, automatic wavelength selection, and a preprogrammed method timer. The result, units, and parameter names are displayed immediately, with no countdown. The large digit display is very easy to read.
- The ATO-CM-SC-10 retains the selected method until a new method is entered, even if it is turned off and then back on. This allows a series of analyses to be performed for the same parameter without reselecting the method.
- Data logging capability includes push-button record management. Easily store data in the field for later access, with no delay in testing. The instrument stores up to 99 measurements in internal, non-volatile memory. Data stored includes date/time, parameter, program number, concentration/absorbance/%T, sample number, and instrument serial number.
- Results are displayed directly in units of concentration, absorbance, or % transmittance. In many methods, concentration in alternate chemical forms is also available. For example, phosphate readings are available as P, PO4, and P2O5. Displayed results can be changed from one form to the next at the touch of a button.
- The User-program feature allows users to generate up to 10 custom procedures, with up to 12 data points each, and store them in a non-volatile instrument memory for later use.
- Advanced software includes an automatic correction for reagent blanks and the option to fine-tune calibration curves with the standard adjust feature.
- Batteries provide self-contained power for field testing.
Accessories Simplify Data Management
The Data Transfer Adapter (DTA) fits on the colorimeter and accepts data sent from the instrument’s infrared LED transmitter. The DTA converts data to a standard format and connects directly to a computer or printer. Data can be printed or downloaded conveniently, after storage, or during collection. Information including date/time, parameter, concentration/absorbance/%T, sample number, operator identity, and instrument serial number is accepted and stored in either text or tabular (spreadsheet) format, and can be easily transferred to a popular spreadsheet or word-processing applications.
Easy Quality Control
The standards are the optional choice to verify the performance of your ATO-CM-SC-10 Colorimeter in seconds. Standards are formulated with neutral density gel that produces similar absorbance readings at any wavelength. For all parameters at all wavelengths, running three secondary absorbance standards will verify your instrument’s calibration easily, anytime.
