The Acrylic Calibration Stick (Part number 480909) is a quick and easy way to confirm (verify) your photometer is functioning within factory specifications hourly, daily, weekly, or monthly (according to your frequency of using the Acrylic Calibration Stick).

The Calibration Stick is reusable as many times as you want.

NOTE. The Calibration Stick only verifies the calibration of your meter and does not actually calibrate the instrument. All of our photometers are factory calibrated and no calibration is required or possible throughout the lifetime of the meter. This Calibration Stick is used to make sure your instrument functions the same at Day 1 from purchase as it will do on Day 100 and Day 1000 and so on.

Used in the following photometers:

• eXact Micro 20
  
• eXact Eco-Check
