You are drawing sweeping conclusions from one example, and without really explaining how you judged the lack of accuracy. Even if you are right in this instance and intra-instrument agreement is the cause, it doesn't follow that all colorimeters have the same issues with intra-instrument agreement. The DTP94 (for instance) has a good reputation in this area. Graeme Gill.
