Performance Features

Microcomputer balancing temperature-humidity control improves stability for qualification, conditioned storage and repeatable environmental testing. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.
Imported compressor, fan and humidity-sensor components support dependable chamber performance across long laboratory schedules. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.
Mirror-finish stainless-steel interior and removable shelf supports make cleaning and chamber reconfiguration easier between test programs. This helps support repeated cleaning, chamber hygiene and long-duration laboratory use.
Independent over-temperature protection helps stop the chamber and notify operators when abnormal conditions appear. This reduces operational risk by helping protect samples and notifying operators when abnormal conditions occur.
Side test-port access supports external probes and measurement tasks during chamber verification or method development. This supports more reliable day-to-day use in industrial research, biotechnology testing, textile testing, material performance evaluation, product packaging studies and shelf-life or stability work.
Optional program control, communication, printer and wireless-alarm functions help document and supervise temperature-humidity studies. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.

APPLICATION SCOPE: Suitable for industrial research, biotechnology testing, textile testing, material performance evaluation, product packaging studies and shelf-life or stability work in universities, research institutes, pharmaceutical quality-control laboratories, agricultural research programs and industrial test environments that require controlled chamber operation.

HANDLING: Confirm installation space against 850 x 1100 x 1930 mm, prepare the specified power supply, and keep air inlets, test ports, shelving, drain areas, doors and controller surfaces accessible for cleaning and maintenance. Every unit is shipped with reinforced packaging to reduce movement and impact during transport; keep the packed chamber upright and use suitable lifting equipment during unloading and positioning.

IMPORTANT NOTICE: Confirm the exact controller type, lighting form, humidity function, communication option and accessory package before ordering. Any displayed amount refers to the chamber body only and does not include freight. Freight is quoted separately and should be confirmed according to the delivery location and shipping method.

The LHS-500HC-II constant temperature and humidity chamber requires specific environmental and infrastructure conditions for safe and reliable operation. Adherence to these constraints ensures proper performance and longevity of the equipment.

Ambient Temperature: The chamber must be operated in an ambient temperature range of 5 to 35°C.
Power Supply: The chamber requires a dedicated AC 220V, 50Hz power supply capable of delivering 3850W.
Installation Clearance: The installation space must accommodate the external dimensions of 850 x 1100 x 1930 mm with adequate clearance for air circulation and access.
Accessibility for Maintenance: Air inlets, test ports, shelving, drain areas, doors, and controller surfaces must remain accessible for cleaning and maintenance.
Transport Handling: During transport, the packed chamber must be kept upright and moved using suitable lifting equipment.

HowTo

This procedure outlines the initial handling, installation, and setup steps to ensure safe and proper operation of the chamber. Follow these steps sequentially to avoid damage and ensure correct configuration.

Required Equipment: Suitable lifting equipment (e.g., forklift or pallet jack)

Unload and Position the Packed Chamber
Keep the packed chamber upright and use suitable lifting equipment during unloading and positioning.
Confirm Installation Space
Confirm that the installation space meets the external dimensions of 850 x 1100 x 1930 mm with adequate clearance.

FAQ

What is the temperature fluctuation tolerance of the LHS-500HC-II chamber at high versus low temperature settings?

The chamber provides ±0.5°C fluctuation at high temperature and ±1°C at low temperature, as specified in the technical data. This difference reflects the balancing control logic of the microcomputer controller and the compressor performance across the operating range.

Can the LHS-500HC-II constant temperature and humidity chamber be integrated with external monitoring systems for data logging?

Yes, the chamber offers an optional RS232/485 communication interface and software for data output and external monitoring. Additionally, the side test port (standard) allows insertion of external probes for independent measurement verification during experiments.

What are the installation and power requirements for the 500L constant temperature and humidity chamber?

The chamber requires a 3850 W, AC 220 V, 50 Hz power supply and an ambient operating environment of +5 to 35°C. Installation space must accommodate external dimensions of 850 x 1100 x 1930 mm, with clear access to air inlets, test ports, shelving, drain areas, doors, and controller surfaces for cleaning and maintenance. The unit includes independent over-temperature protection that stops the chamber and alerts operators in abnormal conditions.

Assessment

This 500L constant temperature and humidity chamber (Model LHS-500HC-II) provides stable environmental control via a microcomputer balancing controller and imported compressor, fan, and humidity sensor, making it suitable for industrial research, stability testing, and material evaluation. However, its 3850 W power draw and limited temperature/humidity ranges (10–70°C, 40–95%RH) require careful lab infrastructure planning and restrict low-humidity or sub-ambient applications.

Positive

Balanced temperature-humidity control logic: Microcomputer balancing control improves stability for qualification, conditioned storage, and repeatable environmental testing across humidity-sensitive applications.
Imported key components for reliability: The use of an imported compressor, circulation fan, and humidity sensor supports dependable performance over extended laboratory schedules, reducing downtime.

Trade-offs

Requires dedicated electrical infrastructure: The 3850 W power draw at AC 220V/50Hz and external dimensions of 850 x 1100 x 1930 mm demand careful lab layout planning and adequate power supply capacity.
Limited temperature and humidity range: Temperature control is restricted to 10–70°C and humidity to 40–95%RH, making the unit unsuitable for low-humidity or sub-ambient testing without additional conditioning modules.
