The Temperature chamber series provides an economical and space-saving solution for a variety of temperature testing requirements.
Temperature Only Test Chambers
Temperature chamber models designed to save lab space
The Temperature chamber series provides an economical and space-saving solution for a variety of temperature testing requirements.
Lowest temperature: -20 or -70°C (-4 or -100°F)
Highest temperature: 180°C (354°F)
The extended temperature ranges of the Standard series make testing at extreme conditions possible without buying a larger, stand-alone chamber. Two chamber sizes are available, as well.
The programmer includes a temperature alarm as just one part of Grande's three-tiered over-temperature protection system. A thermal fuse and a user-set independent limit are also included. In addition, a specimen power terminal allows the user to safely operate powered equipment inside or with the chamber.
Features
High performance and quiet operation (65 dBa)
Space-saving footprint, designed for flush installation to wall
Stainless steel exterior
Full thermal break around doorframe
One 50mm (2") or 100mm (4") diameter cable port on left, with flexible silicone plug
Three levels of overheat protection, plus overcool protection
Easy lift-off service panels, electrical access on left
Detachable eight-foot power cord with plug
ETL listed electrical panel conforming to UL 508A
Touch-screen programmer/controller with Ethernet
Save 120 profiles with up to 1200 steps each (ramp, soak, jump, auto-start, end)
One event relay for external device control, plus specimen power interlock relay for safety
Grande exclusive options include: Web Controller for full remote access; Chamber Connect software for basic data logging and monitoring. USB and RS-232 ports available, as well.
