Redi-Check® is an easy, economical way to monitor calibration, linearity, and repeatability of Stat Fax® chemistry analyzers and many other filter photometers (both aspirating and tube reading).

Each kit comes with Calibration charts, linearity plots and repeatability records.

Red-Check® is quick and easy... dilute, read, and compare results with pre-determined acceptance ranges. Simulates true test conditions using your own glassware.

• Graphic records provide instant visual interpretation.
• Includes data for wavelengths from 340nm - 650nm.
• Acceptance ranges are provided for both bichromatic and monochromatic readings.
• NIST traceable absorbance calibration.
• Long shelf life at room temperature.
