Performance Features

10%RH to 95%RH humidity capability expands the chamber for broader conditioning and stability-study workflows. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.
Imported capacitive humidity sensing avoids wet-bulb maintenance and supports continuous real-time humidity monitoring. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.
Color touchscreen programming provides multilingual operation, live curve display and easier segment editing for staged methods. This improves parameter review, setpoint editing and day-to-day operation in controlled chamber workflows.
PID control and imported sealed-compressor refrigeration help improve control accuracy, running efficiency and chamber stability. This helps maintain dependable low-temperature performance and stable chamber recovery during repeated use.
Independent alarm and protection functions cover over-temperature, overload, over-current, compressor overheating, fan overheating and water-shortage conditions. This helps maintain dependable low-temperature performance and stable chamber recovery during repeated use.
Optional printer, communication, wireless-alarm and App functions help preserve records and monitor chamber status away from the instrument. This reduces operational risk by helping protect samples and notifying operators when abnormal conditions occur.

APPLICATION SCOPE: Suitable for pharmaceutical storage studies, materials conditioning, electronics testing, cosmetics evaluation and controlled humidity laboratory research 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 740 x 1105 x 1680 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 indoor laboratory environment with dedicated power and space clearance. Transport and positioning must maintain upright orientation and use appropriate lifting equipment to prevent damage.

Installation Environment: The chamber must be installed in a stable indoor laboratory with adequate service access on all sides.
Power Supply: The chamber requires a dedicated AC 220 V, 50 Hz power supply capable of delivering 3950 W.
Transport Orientation: The packed chamber must be kept upright and moved using suitable lifting equipment to prevent damage.
Accessibility: Air inlets, test ports, shelving, drain areas, doors, and controller surfaces must remain accessible for cleaning and maintenance.
Safety Protection: The chamber's independent alarm and protection functions for over-temperature, overload, and other conditions must not be bypassed.

FAQ

What is the temperature uniformity specification for the Atomfair AF-BH2250 constant temperature and humidity chamber at high versus low temperature operation?

The chamber maintains ±0.5°C uniformity at high temperature (above 0°C) and ±1°C at low temperature (below 0°C), as stated in the technical specifications. This level of control supports applications such as pharmaceutical stability studies and materials conditioning where consistent thermal distribution across the 248 L working volume is critical.

Does the BH-250CA constant temperature and humidity chamber support RS485 communication and data logging for compliance monitoring?

Yes, the chamber offers an optional RS485 communication interface and software, along with optional embedded printer, wireless alarm, and App control system. The standard color touchscreen controller already includes operating-log functions and a curve display, enabling data review and programmable segment logging (100 programs, 1000 segments, 999 cycles) for record-keeping in regulated environments.

What electrical and spatial requirements are needed for installing the Atomfair 248 L constant temperature and humidity chamber?

The chamber requires a 220 V, 50 Hz power supply with a 3950 W input, and must be installed in a stable indoor laboratory with service access around the unit. Its external dimensions are 740 x 1105 x 1680 mm, so the installation space should accommodate these dimensions with clearance for ventilation, test ports, and maintenance access to the drain area and controller.

Assessment

This 248 L constant temperature and humidity chamber offers a -20 to 100°C range and 10-95%RH humidity control with a color touchscreen programmer, making it suitable for pharmaceutical stability studies and materials conditioning, though its 3950 W power draw and 1680 mm height demand careful lab infrastructure planning.

Positive

Wide humidity range 10-95%RH: The 10%RH to 95%RH humidity capability expands the chamber for broader conditioning and stability-study workflows, supporting humidity-sensitive incubation, cultivation, and stability-study applications.
Capacitive humidity sensor avoids wet-bulb maintenance: Imported capacitive humidity sensing eliminates wet-bulb maintenance and supports continuous real-time humidity monitoring, reducing routine upkeep and improving measurement reliability.

Trade-offs

High power consumption 3950 W: The 3950 W power requirement demands a dedicated AC 220 V, 50 Hz circuit and may increase operational energy costs, requiring careful electrical infrastructure planning.
Large external footprint requires space: External dimensions of 740 x 1105 x 1680 mm require significant laboratory floor space and clearance for service access, which must be confirmed before installation.
