Versatile Block Heaters for Every Application

OHAUS offers versatile dry block heaters that are perfect for applications requiring temperature stability. These units are designed for daily use with accessories meant for each application.

All block heaters hold two optional interchangeable modular blocks with more than 40 options. They can be used easily and do not require any tools. In addition, close tube-to-block contact allows the highest heat retention, leading to efficient heating.

Digital models provide excellent temperature stability and uniformity for repeatable results. Non-digital models offer a low-cost choice.
