Overview
The Bench-top Temperature & Humidity Test Chamber DTH-80 Series is a compact laboratory chamber for precise environmental testing of small samples. It provides controlled temperature and humidity conditions for R&D, quality control and certification testing in space-limited environments.

Description
The benchtop chamber features a 7-inch PLC color touch display, integrated temperature and humidity control, and multiple safety protections. Its compact desk/tabletop format makes it suitable for electronics, materials, pharmaceutical and educational labs that require repeatable thermal and humidity profiles for small specimens.
