Hach DR 4000 UV-Vis Spectrophotometer is accurate, easy to use, and affordable! By design, the Hach DR/4000 is ideally suited for both routine testing and demanding analysis in water treatment, industrial processes, surface finishing, food and beverage processing, pharmaceutical production, and chemical synthesis.
The DR/4000’s innovative sample modules slide in and to accommodate manual testing modules, multi-position carousels, pour-thru cells, a sipper system module, and a temperature control module. Plus, more than 130 preprogrammed use PA accepted Hach methods are permanently stored in instrument memory, and you may add up to 100 calibrations of your own.
Using the DR/4000's sophisticated software and advanced interactive user interface, you can call up programs and wavelengths with just a few keystrokes. You get fast, accurate and convenient testing results when you use the DR/4000 with Hach simplified methods and prepared reagents.
The DR/4000 Spectrophotometer's optical design allows for an exceptionally stable analysis system to be compacted into a small, efficient package. A large graphical display with adjustable LCD shows graphical representations of wavelength scans, and peaks and valleys are available in tabular form.
Flexible software means you can choose readout values in concentration, ABS or %T, scan any wavelength range, perform time-course operations, or use the innovative standard addition function to check for accuracy.
DR/4000 V has visible spectrum capabilities with range of 320 to 110 mm

When this equipment is being turned on, it performs all self test but fails wavelength calibration check. With this, we can not use the equipment. We later managed to turn it, and it passed all self tests.
What must I do to overcome this great...
