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 550 x 790 x 1080 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 dedicated power supply of 2000 W at AC 220 V, 50 Hz and must be operated in an environment between +5 and 35°C. The unit must be kept upright during transport and positioned with adequate clearance for all service points.

Power Supply Constraint: Connect the chamber only to a dedicated AC 220 V, 50 Hz power source rated for 2000 W.
Operating Environment Constraint: Maintain the ambient temperature between +5 and 35°C to prevent condensation and ensure stable humidity control.
Orientation Constraint: Always transport and position the chamber in an upright orientation to avoid compressor damage.
Clearance Constraint: Keep air inlets, test ports, shelving, drain areas, doors, and controller surfaces accessible for routine cleaning and maintenance.

HowTo

Follow these steps to unpack, position, and power on the chamber for the first time. Ensure that all installation space and power requirements are met before operation.

Required Equipment: Lifting equipment

Inspect packaging
Inspect the chamber packaging for damage and keep the unit upright during transport to prevent compressor oil migration.
Position chamber
Position the chamber in the installation space, maintaining accessible clearance around air inlets, test ports, shelving, drain areas, doors, and controller surfaces.
Connect power
Connect the chamber to a dedicated AC 220 V, 50 Hz power supply rated for 2000 W.
Set environment
Set the operating environment temperature between +5 and 35°C to ensure stable chamber performance.

FAQ

What is the temperature stability specification for the LHS-80HC-II at high versus low temperature setpoints?

At high temperature ranges, the chamber achieves a temperature fluctuation/uniformity of ±0.5°C, while at low temperature ranges it is ±1°C. This difference is stated in the technical specifications for the LHS-80HC-II model, which covers a full control range of 10 to 70°C.

Can the Atomfair AF-LH20180 constant temperature and humidity chamber be connected to a laboratory data acquisition system for remote monitoring?

Yes, the chamber supports optional RS232/485 communication interface and software, which enables data output and integration with external monitoring systems. Additionally, a side test port is provided for external probe access during chamber verification or method development.

What are the electrical and spatial installation requirements for the 80L professional constant temperature and humidity chamber?

The chamber requires an AC 220V, 50 Hz power supply with a 2000 W capacity. Its external dimensions are 550 x 790 x 1080 mm, and it must be operated in an ambient environment of +5 to 35°C.

Assessment

The Professional Constant Temperature and Humidity Chamber (80 L, with Printer) offers reliable balancing humidity control from 40% to 95% RH and temperature range of 10 to 70°C, with an imported compressor and humidity sensor. Its mirror-finish stainless steel interior and side test port support cleaning and external probe access, but the 2000 W power requirement and ±3%RH humidity deviation impose operational constraints.

Positive

Balancing temperature-humidity control: Microcomputer balancing control logic maintains stable temperature and humidity conditions, critical for repeatable environmental testing in incubation, cultivation, and stability studies.
Imported compressor and humidity sensor: Reliable performance from imported compressor, fan, and humidity sensor components supports long-duration laboratory schedules and consistent chamber operation.

Trade-offs

High power requirement (2000 W): The chamber requires 2000 W at 220 V, 50 Hz, necessitating appropriate electrical infrastructure and circuit capacity in the lab.
Humidity deviation ±3%RH: The specified humidity deviation of ±3%RH may limit suitability for applications requiring tighter humidity accuracy, such as certain pharmaceutical stability tests.
