Overview Manuals Optical Path Methods Data Handling Sample Cells

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.
Description

HACH DR3900 LPG440.99.00002 is the non-RFID configuration of the DR3900 laboratory visible spectrophotometer. Its spectral reference-beam optics cover 320–1100 nm and support absorbance, transmittance, concentration, and wavelength-scan measurements for water-analysis methods.

Inside DR3900 LPG440.99.00002, the halogen source and monochromator select the programmed wavelength before the detector compares the sample beam with the reference path. The instrument converts that optical result into the selected measurement mode and stores it with the associated sample and operator data.

The touchscreen of DR3900 LPG440.99.00002 combines method selection, sample measurement, and result review, while its USB and Ethernet interfaces separate local data transfer from network communication. Because this configuration omits RFID, sample identification uses the instrument’s standard manual-entry, barcode, and wired data paths.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What distinguishes HACH DR3900 LPG440.99.00002 from an RFID-equipped DR3900?
HACH DR3900 LPG440.99.00002 retains the standard DR3900 optical and data functions but omits the RFID sample-identification workflow.
Which measurements can HACH DR3900 LPG440.99.00002 perform?
Depending on the selected method, HACH DR3900 LPG440.99.00002 reports transmittance, absorbance, concentration, or a wavelength scan across its visible-spectrum range.
How does the reference beam work in HACH DR3900 LPG440.99.00002?
Within HACH DR3900 LPG440.99.00002, a separate optical reference is compared with the sample path to account for changes in the light and optical system.
Where are custom methods stored on HACH DR3900 LPG440.99.00002?
User-program memory in HACH DR3900 LPG440.99.00002 stores laboratory methods in addition to its factory-programmed procedures.
How can results leave HACH DR3900 LPG440.99.00002 without RFID?
Stored records from HACH DR3900 LPG440.99.00002 can be transferred through USB media, a USB computer link, or Ethernet.
Why must the cuvette type match the method on HACH DR3900 LPG440.99.00002?
Each programmed calculation on HACH DR3900 LPG440.99.00002 assumes a defined sample-cell geometry and optical path length, so the selected cell format must match the method.
