DR1900 Portable Spectrophotometer for field measurements of chemical composition of water
Description of equipment
Technical data:
- Measured properties: depending on the purchased additional equipment (220 pre-programmed methods) - concentration of each chemical parameter (currently Fe2+ and Mn) in the water
- Operating conditions: 10–40 °C (50 to 104 °F); up to 80-% relative humidity (non-condensing); relative humidity: max. 80 % relative humidity, non-condensing; temperature: 10–40 °C
- Detector: silicon photodiode
- Photometric linearity: < 0.5 % (0.5 – 2.0 Abs)
- Photometric accuracy: ± 0,003 Abs at 0,0 to 0,5 Abs
- Wavelength selection: automatic
- Photometer measurement range: 0–3 Abs (wavelength 340–800 nm)
- Mode of action: transmittance (%), absorbance and concentration
- Wavelength accuracy: ± 2 nm (340 - 800 nm range)
- Wavelength range: 340–800 nm
- Pre-programmed methods: 220 (Note: Measurement with LCK cuvette tests is possible, but without the 2D barcode reading function and 10-fold evaluation.)
- Diffused light: < 0.5 %T at 340 nm with NaNO2
- Temperature range: 0 - 50 °C (32 - 122 °F)
- Wavelength calibration: automatic
- Data record: 500 measured values (result, date, time, sample ID, resistor ID. for good lab practice)
- Display: LCD (backlight): 240 or 160 pixel graphic display (LCD, B&W, backlit)
- Cuvette compatibility: 10 mm square/1-inch square and 13-mm/1-inch round; 13 mm and 1-inch round, 10 or 10 mm 1-inch square; – adapter for round vials and 10 x 10 mm
- Battery life: 15 days (normal) at 5 measurements per day, 5 days per week without display illumination
- Optional purchase of additional equipment (powder pillow, LCK cuvette tests, Liquid Reagent test or Accuvacs
Access to equipment of equipment
The device is used to make measurements on water samples in the laboratory or in the field. The device is currently used for Fe2+ and manganese measurements (field measurements) in water.
Equipment rental
Measurements are also carried out for external clients on samples in the GeoZS laboratory or in the field.
