TH3-TG-1500 Constant Temp. & Humidity Chamber (1450L)
TH3-TG-1500 Constant Temp. & Humidity Chamber (1500L Class)
SKU / Cat. No.: AAHC20352KThe TH3-TG-1500 is a high-capacity constant temperature and humidity chamber designed for long-term stability and environmental testing. Its 1500-class cabinet provides 1450 L / 51.2 cu ft (nominal 1500 class), with a -5 to 100°C temperature range and 20 to 95% RH humidity control for demanding ICH Q1A(R2) stability studies.
A differentiated external humidification system, insulated and double-sealed door construction, heated viewing window, and LED interior lighting help maintain stable conditions while making samples easy to observe. The chamber is suited to pharmaceutical, biotechnology, electronics, materials, and quality-control laboratories that require repeatable long-duration testing.
Key Features and Benefits
Stable Test Environment
- Temperature range from -5 to 100°C without humidity control.
- Humidity range from 20 to 95% RH within the published operating envelope.
- Stable temperature and humidity control for long-term operation.
- Supports stability testing in accordance with ICH Q1A(R2) guidelines.
- External humidification system simplifies maintenance and cleaning.
- Excellent insulation and double-sealed door support reproducibility.
Convenient Daily Operation
- Large color touch display with useful graph 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.
- Removable refrigerator condenser grill for easier cleaning.
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.
Safety Systems
