Portable multi-parameter colorimeter DR890

Portable multi-parameter colorimeter Model: DR890 instrumental data: DR / 800 series single wavelength colorimeter, measurement parameters, more stable performance, DR820 / DR850 / DR890 variety of models, portable, and can store measurement data. RS-232 communication interface DR / 800 Series Colorimeter specially designed for field testing, easy to carry, to provide rapid test results for water quality analysis. Easy to use, each colorimetric parameters are preset calibration curve method selection buttons and automatic wavelength selection, analysis requires very little time and preparation, the results directly show the concentration of light transmittance or absorbance in the LCD screen. This handheld colorimeter There are three models to choose from: DR / 820, DR / 850 and DR / 890, respectively, can test up to 20, 50 or 90 kinds of parameters, each model are dust, corrosion, waterproof. DR / 800 Series Colorimeter includes many advanced parameters: Preset good way of data recording capability up to 50 kinds of measurements can remember the last time the procedure to change the display mode can store the results of five operator input method when combined with Hach COD reactor and the prepared reagent bottle used in conjunction analysis provides COD choose traditional methods or the new manganese Ⅲ law, can remove heavy metals interference Technical parameters: Wavelength Selection: Automatic selection luminosity (Photometric) Range: 0 ~ 2A operational modes: concentration, ABS,% T concentration units: μg / L, mg / L, g / L, ABS,% T External output: the DateTransferAdapter the RS232 output (Optional Accessories) store data: 50 samples reading, each reading includes date / time, parameters, program number, concentration, absorbance, transmittance, sample number, instrument number display: liquid crystal (LCD) display the measurement results, parameters and unit size: 23.6 × 8.7 × 4.7 cm (9.3 × 3.4 × 1.9 ") Weight: 470g (1lb) Power: 4AA alkaline batteries or rechargeable batteries, the normal working life of 6 months Temperature range: -40 to 60 ℃ (-40 to 140 ℉) Operating temperature range : 0 to 50 ℃ (32 至 120 ℉) Environment: IP67 rated water depth of 1 meter 30 minutes can be waterproof, dustproof image preview:
