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 690 x 800 x 1430 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 chamber requires a controlled installation environment with ambient temperature maintained between +5 and 35 °C and a dedicated AC 220 V, 50 Hz power supply rated at 2100 W. The unit must be positioned with clear access to air inlets, test ports, shelving, drain areas, doors, and controller surfaces for routine cleaning and maintenance.

Environmental Installation Constraints: Confirm the installation space accommodates the external dimensions of 690 x 800 x 1430 mm and that the working environment temperature remains within +5 to 35 °C to ensure specified performance.
Power Supply Requirement: Prepare a dedicated AC 220 V, 50 Hz power supply capable of supporting the 2100 W input, and verify electrical compatibility before connection.
Accessibility for Maintenance: Keep air inlets, test ports, shelving, drain areas, doors, and controller surfaces accessible to allow proper airflow, cleaning, and maintenance procedures.
Transport and Positioning Constraint: Keep the packed chamber upright during transport and use suitable lifting equipment during unloading and positioning to prevent damage.

HowTo

This procedure covers the initial installation, power connection, and pre-operation verification of the chamber. Follow these steps to ensure safe setup and reliable environmental control.

Required Equipment: Suitable lifting equipment, AC 220 V, 50 Hz power supply

Position the chamber
Position the chamber in its final location, ensuring the external dimensions of 690 x 800 x 1430 mm fit within the allocated space and that air inlets, test ports, and controller surfaces remain accessible.
Verify environmental conditions
Verify the ambient temperature of the installation room is between +5 and 35 °C to maintain specified performance.
Connect the power supply
Connect the chamber to a dedicated AC 220 V, 50 Hz power supply rated for at least 2100 W, confirming the electrical outlet matches the plug configuration.
Check chamber interior and accessories
Inspect the mirror-finish stainless-steel interior, confirm all 3 shelves are properly installed, and ensure the side test port is unobstructed.
Power on and set parameters
Power on the chamber and use the microcomputer controller to set the desired temperature within 5 to 80 °C and humidity within 40% to 85% RH.
Allow stabilization
Allow the chamber to stabilize at the set conditions, monitoring the display to confirm temperature fluctuation remains within ±0.5 °C at high temperature and ±1 °C at low temperature, and humidity deviation within ±3% RH.

FAQ

What is the significance of the different temperature fluctuation specifications at high and low temperature ranges for humidity-sensitive incubation studies?

The chamber specifies ±0.5°C fluctuation at high temperature and ±1°C at low temperature, which is typical for compressor-based systems. This means tighter control at higher temperatures, while low-temperature operation may exhibit slightly more variation. Users designing protocols that require precise low-temperature humidity control should account for this ±1°C fluctuation to ensure stability of sensitive samples.

Can the chamber be connected to a laboratory environmental monitoring system for data logging and remote supervision?

Yes, the chamber supports optional RS232/485 communication interface and software, enabling data logging, remote monitoring, and integration with laboratory information systems. This is an optional accessory that must be specified at the time of order, as it is not included in the base configuration.

What are the critical installation and power requirements for this 150 L chamber?

The chamber requires an external footprint of 690 x 800 x 1430 mm and a power supply of AC 220 V, 50 Hz, 2100 W. Ensure adequate ventilation and access to the side test port, shelving, and drain areas. The unit is shipped with reinforced packaging and must be kept upright during transport; use suitable lifting equipment for unloading and positioning.

Assessment

The Professional Constant Temperature and Humidity Chamber, 150 L (Model LHS-150HC-I) delivers 150 L capacity with microcomputer balancing temperature-humidity control, mirror-finish stainless-steel interior, and imported compressor for stable environmental testing. However, its humidity range is limited to 40-85%RH with ±3%RH deviation, and low-temperature uniformity is ±1°C, requiring careful consideration of application requirements and ambient conditions.

Positive

Balancing temperature-humidity control: Microcomputer balancing control logic improves stability for qualification, conditioned storage, and repeatable environmental testing, supporting humidity-sensitive incubation and stability studies.
Imported compressor and sensor components: Imported compressor, circulation fan, and humidity sensor deliver dependable long-term chamber performance across extended laboratory schedules, reducing maintenance intervals.

Trade-offs

Limited humidity range and deviation: Humidity control is restricted to 40-85%RH with ±3%RH deviation, excluding applications requiring low-humidity (below 40%RH) or tight humidity tolerance (±1%RH).
Low-temperature uniformity ±1°C: Temperature fluctuation at low range is ±1°C, less precise than high-range ±0.5°C, and the chamber requires a stable ambient environment of +5 to 35°C to maintain performance.
