The XD 7500 is a UV-VIS Spectrophotometer. It combines a state-of-the-art optical system with ease of use and flexibility for a wide range of water testing applications. By providing users with the full range of functions that is required from a spectrophotometer, including the ability to measure transmission and absorbance; the scanning of spectral data; recording of kinetic measurements; and the ability to create custom measurement methods, the XD 7500 is the ideal spectrophotometers for water quality testing in the laborarory.

Description

Optimized for Water Quality Analysis
Pre-programmed with over 150 analytical methods that cover a wide variety of applications and industries. All methods are compatible with Lovibond® reagents.
Intuitive Interface that Prevents Measurement Errors
Save time and eliminate errors with the automatic test recognition feature. Each Lovibond® method is recognized by the instrument with a barcode, which ensures the instrument is in the correct measurement mode before taking a reading. The automatic cuvette type detection feature confirms that the proper vial is being used with the test, which is a critical component to achieving accurate results.
Analytical Quality Assurance
Standard procedures for analytical quality assurance support the verification of the photometer, the overall system (including the chemical methodology) and the verification of matrix effects. Support of analytical quality assurance procedures include the ability to set tolerances and reminders for calibration protocols.
User Security for Data Protection
Create up to 3 different user levels with password protection. Each user account can be assigned a level of access to the instrument, ensuring users only have access to what they need.
Custom Measurement Methods
Users can create their own methods based on up to ten wavelengths with various mathematical operations.
