Ohaus 4 Block Dry Block Heaters

Ohaus 4 Block Dry Block Heaters are ideal for applications that require temperature stability. All units hold 4 optional interchangeable modular blocks with over 40 choices. Blocks are easy to use, no tools required. Close tube-to-block contact enables maximum heat retention, resulting in efficient heating. Digital models offer exceptional temperature uniformity and stability for repeatable results, while non-digital models are an economical choice.
