Isotech manufactures a wide range of dry block calibrators. To select the appropriate drywell calibrator you should be able to answer the following questions;

1) What Temperature range do I need to cover?

2) What's more important to me, speed of changing temperatures or stability, capacity and immersion depth of the block?

3) What basic accuracy do I need or will I use a Reference Thermometer as my temperature standard?

4) Would I like the flexiibility to change my dry block calibrator into a liquid bath, blackbody source, or Fixed Point apparatus?
