Generic pocket colorimeter DR300 instruments are intended for customised applications not included in standard analysis systems. They are available in a range of wavelengths appropriate for many custom calibrations. In addition to the factory absorbance calibration (0 to 2,5 A), the instruments offer two user-entered, two-point linear calibrations, and provide a choice of either 0,00 to 2,55 or 0,0 to 99,0 for the display value.
- Single parameter
- Waterproof, lightweight, rugged
- Backlit display
- Data logging recall function
These instruments accept two user-prepared calibration curves. The calibration curve can be from 0 to 2,5 absorbance. Make sure that the calibration curve includes standard values that are less and more than the range of interest. The instrument range will be the same as the calibration range. For example, when the standards that are used are 1,00; 2,00 and 4,00, the instrument range is 1,00 to 4,00. There are two options to enter a user calibration curve:
- By standards: Standard solution values are entered with the keypad and the absorbance values are measured
- By data entered via keypad: Standard solution values and absorbance values are entered using the keypad.
Ordering information: Reagents must be purchased separately.
Delivery information: Each DR300 pocket colorimeter is delivered as an instrument kit in a sturdy custom carrying case, including batteries, sample cells (1" Ø and 10 mm Ø, two of each), and a printed user manual.
