TH3-G-408 Low Temp. & Humidity Chamber (408L)
TH3-G-408 Low-Temperature Temperature & Humidity Chamber (408L)
SKU / Cat. No.: AAH800333KThe TH3-G-408 provides 408 L / 14.4 cu ft of controlled test space and extends temperature conditioning down to -40°C. Designed for heat and cold resistance, combined temperature cycling, and long-term humidity testing in accordance with IEC, MIL, and related international test methods, it delivers stable control in a compact floor-standing cabinet.
A differentiated external humidification system, double-sealed door construction, heated viewing window, and LED interior lighting support repeatable conditions and convenient sample observation. Optional inner glass door and hand-in port access help reduce chamber disruption during long-term testing.
Key Features and Benefits
Low-Temperature Performance
- Temperature range from -40 to 100°C without humidity control.
- Humidity range from 25 to 95% RH within the published operating envelope.
- Stable temperature control during long-term operation.
- Suitable for heat and cold resistance testing.
- Supports combined temperature cycling test methods.
- External humidification system simplifies maintenance and cleaning.
Convenient Daily Operation
- Large color touch display with graph-based status display.
- Level-Checker function for real-time humidification tank monitoring.
- Heated tempered-glass viewing window and LED interior lamp.
- Door-mounted key lock, standard Ø50 mm cable port, and casters.
- Easy water refilling during operation; direct water supply is optional.
- Optional cable ports on both sides and compact installation footprint.
Control, Programming, and Connectivity
The multifunction controller stores up to 100 patterns and 100 segments per pattern, with a maximum of 2,000 segments overall. Auto-tuning and temperature calibration support stable control, while 16-zone PID control improves precision. An RS-232 interface is standard, and RS-485 is optional.
Dedicated PC monitoring software is provided for up to four units. Optional LC Connected mobile monitoring requires LC GreenBox, while LC DataKeeper software provides a 21 CFR Part 11-compliant environment for GMP audit support. Validation support for IQ, OQ, and PQ is also available as an option.
