Temperature Humidity Chamber 50 L AF-LHB0050 ATOMFAIR®

Balanced-Control Constant Temperature and Humidity Chamber, 50 L

Research-grade laboratory product

Product Overview

Balanced-Control Constant Temperature and Humidity Chamber, 50 L is a balanced-control constant temperature and humidity chamber built for animal, textile, food-processing, material and packaging tests that require balanced temperature-humidity chamber control. This configuration provides 50 l chamber volume, RT+10 to 85 C, 80%rh to 95%rh humidity control, mirror-finish stainless-steel chamber interior and microcomputer balancing temperature and humidity controller for stable day-to-day laboratory operation.

This family combines fluorine-free design, mirror-finish stainless-steel inner chamber, balancing control, imported key components, independent over-temperature alarm and a 25 mm test port as core construction points. The chamber combines environment-friendly refrigeration system on CL, CA and CB versions with imported humidity sensor and balancing-control package, 2 shelves and an interior size of 350 x 300 x 500 mm, supporting incubation, cultivation, climate simulation or conditioned test work where repeatable environmental control is important.

The CH, CL, CA and CB configurations give a choice of non-refrigerated and refrigerated temperature bands, allowing users to match humidity-chamber capability to routine environmental tests. Installation planning can be based on the external size of 720 x 620 x 725 mm and the stated power requirement of 1450 W. Optional functions such as rs485 communication interface and software; lcd program controller; wireless alarm system; embedded printer; communication interface and embedded printer are alternative options that should be selected according to the required configuration allow the unit to be adapted for alarm notification, data output, programmable operation, atmosphere support or other application-specific requirements.

Performance Features

Balancing temperature-humidity control helps maintain a stable operating band for routine environmental testing. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.
Mirror-finish stainless-steel inner surfaces with removable shelving make cleaning and chamber preparation easier between test runs. This helps support repeated cleaning, chamber hygiene and long-duration laboratory use.
Independent over-temperature alarm protection improves safety during unattended conditioned testing. This reduces operational risk by helping protect samples and notifying operators when abnormal conditions occur.
Model-specific low-temperature bands let the user choose between non-refrigerated, -10 C, -20 C or -40 C starting points. This supports more reliable day-to-day use in animal, textile, food-processing, material and packaging tests that require balanced temperature-humidity chamber control.
Side test-port access helps chamber verification and external measurement tasks. This supports more reliable day-to-day use in animal, textile, food-processing, material and packaging tests that require balanced temperature-humidity chamber control.
Optional communication, printer, wireless-alarm and program-controller functions support more traceable chamber operation. This improves parameter review, setpoint editing and day-to-day operation in controlled chamber workflows.

APPLICATION SCOPE: Suitable for animal, textile, food-processing, material and packaging tests that require balanced temperature-humidity chamber control 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 720 x 620 x 725 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.

Supplier: Atomfair

Brand: ATOMFAIR®

The chamber requires a stable ambient temperature between +5 and 30°C and a dedicated AC 220 V, 50 Hz power supply. Independent over-temperature alarm must be enabled to protect samples during unattended operation.

Ambient Temperature Range: Operate the chamber only in environments with ambient temperature between +5 and 30°C to maintain proper performance.
Electrical Supply: Connect the chamber to a dedicated AC 220 V, 50 Hz power supply rated at 1450 W to avoid electrical hazards.
Over-Temperature Alarm: Enable the independent over-temperature alarm before any unattended testing to automatically notify operators of abnormal conditions.
Installation Orientation: Keep the chamber upright during transport and positioning, and use suitable lifting equipment to prevent tipping or damage.
Air Inlet and Ventilation: Maintain clearance around air inlets, test ports, and drain areas to ensure proper airflow and prevent overheating.

HowTo

Unpack and position the chamber upright, connect to the specified power supply, and configure the over-temperature alarm before use. Perform routine cleaning of the stainless-steel interior to maintain hygiene and performance.

Required Equipment: Lifting equipment

Unpack and Position

FAQ

What is the effective temperature range of the LHS-50CH humidity chamber without refrigeration?

The LHS-50CH (CH configuration) operates from RT+10°C to 85°C, with no refrigeration function. This means the minimum achievable temperature is 10°C above the ambient room temperature, typically limiting low-temperature testing to around 25-40°C depending on lab conditions.

Can the chamber control humidity below 80% RH?

The humidity control range is specified as 80%RH to 95%RH, with a deviation of +/-3%RH. The chamber cannot control humidity below 80%RH, as it uses a balanced control system without dehumidification capability. For lower humidity requirements, consider refrigerated models (CL, CA, CB) that may offer broader humidity ranges.

What are the space and power requirements for installing the LHS-50CH chamber?

The chamber external dimensions are 720 x 620 x 725 mm, requiring a clear installation footprint. It requires a single-phase AC 220V, 50Hz power supply with a rated input of 1450W. The working environment must be maintained at +5 to 30°C. Ensure adequate ventilation and access to the side test port, drain, and controller surfaces for maintenance.

Assessment

The LHS-50CH 50 L balanced-control constant temperature and humidity chamber provides stable RT+10 to 85°C and 80–95%RH control with mirror-finish stainless steel interior, but lacks refrigeration (cannot cool below ambient) and cannot achieve humidity below 80%RH.

Positive

Balancing temp-humidity control: Microcomputer balancing controller maintains stable operating conditions for incubation, cultivation, and stability studies, reducing drift during long-duration tests.
Mirror-finish stainless steel interior: Smooth, corrosion-resistant inner chamber with removable shelving simplifies cleaning and decontamination between test cycles, supporting laboratory hygiene and repeatability.

Trade-offs

No refrigeration function: This CH model cannot cool below room temperature (minimum setpoint RT+10°C), limiting its use to above-ambient conditions and excluding low-temperature testing.
Restricted humidity range: Humidity control is specified only from 80%RH to 95%RH, preventing low-humidity or desiccating experiments and requiring alternative equipment for drier conditions.
