Box material and insulation
shell1.5mm high-quality cold-rolled steel plate, surface treated with electrostatic spraying for rust prevention.
inner linerSUS304 mirror stainless steel plate, corrosion-resistant and easy to clean.
insulation layer: 100mm thick high-density polyurethane rigid foam or glass fiber cotton, saving energy by more than 30%.
Key component optimization
observation window280 × 350mm multi-layer insulated tempered glass with built-in electric heating and anti frost design, ensuring full visibility throughout the test.
Air duct systemLow temperature resistant long shaft motor+multi wing centrifugal wind turbine, forced three-dimensional turbulent circulation, ensuring temperature uniformity.
test holeThe left side comes standard with Ø 50mm lead holes, high and low temperature resistant sealing design, and supports power on testing.
Safety and Convenience
Mobile Design4 PU movable casters are configured at the bottom, supporting fixation and flexible displacement.
pressure balanceTop pressure relief device, automatically adjusts the pressure difference inside and outside the box to prevent deformation of the door seal.


Small high and low temperature test chamber
Intelligent control core
controllerImported microcomputer integrated temperature and humidity controller (such as TT-5166), supporting interface switching between Chinese and English, program editing (multi-stage programming), and remote monitoring (RS485/Ethernet).
sensorPlatinum resistance PT100 Ω, temperature control accuracy ± 0.1 ℃.
data managementSupports storing test data on a USB flash drive and can be optionally printed to output curve charts.
Refrigeration and Heating System
refrigeration unitFrench Taikang fully enclosed compressor, utilizing cascade refrigeration technology to ensure low-temperature stability at -40 ℃.
heating unitNickel chromium alloy U-shaped heating tube, dynamically adjusted by PID algorithm to avoid temperature overshoot.
