Hach Company DU 800 Series


DU 800 Series

The DU 800 Spectrophotometer is a PC controlled system intended for use in quantitative and qualitative analysis in biological and industrial procedures that require spectrophotometric measurements in the UV and visible region of the electromagnetic spectrum. If the instrument is used in a manner other than as described, the safety and performance of the instrument can be impaired.

The DU 800 Spectrophotometer operates in the wavelength range of 190 to 1100 nm and has a bandwidth of <= 1.8 nm. The focused micro-beam design provides a wide linear range and other specific benefits for small volumes and precious samples. Various accessories are available to address micro-volume samples and individual application requirements.

Wavelength calibration failed , Service Diagnostics Password

Hello Every one : I have two questions. 1) Why I am not able to do the wavelength calibration?  I am sure my instrument is fine (I have checked that with a Holmium cell and I have got the exact number 445.7nm) but It says wavelength...

Beckman Coulter DU 800 not communicating via USB to PC

I have a BC DU 800 that will not communicate with the PC. I have uninstalled and reinstalled the software on the PC like a new installation. The USB port sees the device, the software is seeing the device, but they will not talk. Any suggestions?

Software command set

Does anyone have the software commands for the DU-800, a programming manual, or even better a Labview program to run the instrument.  Can one use the commands used for the DU 640?
