Features:
- Covers the 320–1100 nm visible spectrum with a reference-beam optical system.
- Runs programmed transmittance, absorbance, concentration and wavelength-scan methods.
- Stores measurement records and transfers data through USB or Ethernet without an RFID workflow.
HACH DR3900 LPG440.99.00002 identifies the non-RFID DR3900 instrument configuration.
Its touchscreen links method selection, sample measurement and result review in one operating sequence.
The reference channel helps the photometer separate optical-system variation from the sample response.
The HACH DR3900 LPG440.99.00002 Laboratory Spectrophotometer without RFID may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Light Generation and Measurement
- Lamp: A halogen lamp supplies light across the instrument wavelength range.
- Wavelength Selection: The monochromator selects the programmed wavelength before light passes through the sample cell.
- Reference Path: The spectral reference beam provides a comparison path for the measured sample signal.
Programmed and User Methods
- Programmed Methods: Programmed methods define wavelength, calibration and measurement sequence.
- User Programs: User programs store additional method settings for repeated laboratory work.
- Result Conversion: Absorbance results can be converted into concentration by the selected calibration relationship.
Result Storage and Transfer
- Result Records: Each stored result can include time, sample identification and operator identification.
- USB Transfer: USB supports removable-media and direct computer transfer paths.
- Ethernet Path: Ethernet connects the instrument to supported laboratory data workflows.
Cuvette Selection and Placement
- Cell Formats: The cell compartment accepts supported round and rectangular cuvette formats.
- Path Length: The selected method must match the optical path length of the installed cell.
- Cell Handling: Cell orientation and clean optical faces remain part of the measurement path.
