The Leyro LHC 400 dry block temperature calibrator is a portable device designed for precise calibration of probes and thermocouples. The basic model features a dual display with 0.18°F resolution, ±0.09°F uniformity, and ±0.018°F stability, while the advanced model offers selectable resolutions of 0.18°F, 0.018°F, or 0.0018°F, ±0.054°F uniformity, and stability of ±0.072°F. Both models operate across a temperature range of 104 to 842°F with an accuracy of ±0.18°F.

Its durable aluminum dry block and wide selection of interchangeable inserts accommodate various sensor sizes and types, making it versatile for use in multiple industries. With an immersion depth of 165mm, the LHC 400 ensures secure and stable probe placement. The device offers intuitive menu controls with up to 10 calibration points and optional RS485 Modbus RTU communication for seamless integration into external systems.

The LHC 400 heats from 122 to 797°F in 22 minutes and cools from 797 to 212°F in 35 minutes. Along with a 3-year warranty, the LHC 400 is built for reliable performance in demanding environments such as calibration laboratories, testing laboratories, universities and R&D centers, chemical and pharmaceutical industries, and the food industry.
