This chamber requires a controlled working environment between +5°C and 30°C and a dedicated AC 220V, 50Hz, 1650W power supply. Installation must allow access to all service areas including air inlets, test ports, shelving, drain, doors, and controller surfaces.
- Power Supply Constraint: Must be connected to an AC 220V, 50Hz power source capable of supplying 1650W.
- Working Environment Constraint: Ambient temperature must be maintained between +5°C and 30°C to ensure stable operation.
- Installation Space Constraint: The chamber requires a minimum footprint of 650 x 800 mm and a height allowance of 1310 mm, with clearance for ventilation and access.
- Transport Orientation Constraint: The chamber must be kept upright during transport and positioning to prevent damage to internal components.
This procedure describes the initial setup and positioning of the constant temperature and humidity chamber. Follow these steps to ensure safe installation and prepare the unit for operation.
Required Equipment: Lifting equipment
- Confirm installation space
Confirm that the installation area meets the required external dimensions of 650 x 800 x 1310 mm with adequate clearance. - Prepare power supply
Prepare a dedicated AC 220V, 50Hz power outlet capable of supplying 1650W. - Position chamber
Position the chamber upright using suitable lifting equipment and ensure all service areas remain accessible.
What is the lowest temperature the LHS-100CH (CH model) can achieve, and how does it compare to the refrigerated versions?
The LHS-100CH model operates from RT+10 to 85°C with no refrigeration function, so it cannot achieve sub-ambient temperatures. In contrast, the CL, CA, and CB versions include environment-friendly refrigeration systems that extend the low-temperature range down to -10°C, -20°C, or -40°C respectively. This makes the CH model suitable only for tests above ambient temperature.
Can the LHS-100CH chamber be equipped with an RS485 communication interface for data logging and remote monitoring?
Yes, the LHS-100CH chamber supports an optional RS485 communication interface and software, which allows integration with external data logging and monitoring systems. This option must be selected during ordering as it is not included in the standard configuration. The chamber also offers optional embedded printer, LCD program controller, and wireless alarm system for further connectivity.
What are the electrical supply and ambient temperature requirements for installing the LHS-100CH chamber?
The chamber requires an AC 220 V, 50 Hz power supply with a rated input of 1650 W. It must be installed in a working environment of +5 to 30°C. The external dimensions are 650 x 800 x 1310 mm, so adequate space for ventilation and access to the side test port, drain, and controller should be ensured. The unit also includes an independent over-temperature alarm for safety during unattended operation.
The LHS-100CH (100 L) provides balanced temperature-humidity control with a microcomputer controller and mirror-finish stainless-steel interior for easy cleaning. It is limited to above-ambient temperatures (RT+10 to 85°C) and high humidity only (80–95% RH), making it unsuitable for refrigeration or low-humidity applications.
Positive
- Balanced temperature-humidity control: Microcomputer balancing controller maintains stable environmental conditions for humidity-sensitive incubation, conditioning, and stability tests.
- Mirror-finish stainless-steel interior: Smooth, corrosion-resistant inner surfaces with removable shelving simplify cleaning and reduce cross-contamination risk between test runs.
Trade-offs
- No refrigeration function: This CH model cannot cool below ambient; temperature range is restricted to RT+10 to 85°C, excluding low-temperature testing.
- Limited humidity range: Humidity control is restricted to 80–95% RH, making the chamber unsuitable for low-humidity or desiccating environments.
