The Envirotronics S-H-TM series delivers precision environmental testing across eight to 32 cubic feet of controlled workspace. These chambers maintain temperature stability to ±0.3°C and humidity accuracy to ±2% RH, meeting stringent requirements for product development, quality assurance, and material characterization. Stainless steel construction with heliarc-welded seams and fiberglass insulation ensures repeatability and durability in demanding laboratory and industrial environments.
