Temperature Humidity Chamber 247 L AF-HSP250BE ATOMFAIR®

Temperature and Humidity Chamber, 247 L

Research-grade laboratory product

Product Overview

Temperature and Humidity Chamber, 247 L is a practical chamber for environmental protection, epidemic prevention, veterinary research, drug testing, aquatic research, BOD measurement, microbial culture, plant cultivation and breeding tests. It brings together 247 l of usable space, 5 to 50 C, 50%rh to 90%rh humidity control, so the chamber can keep samples in a steady, repeatable working condition.

The inner door uses tempered glass, the outer door uses a magnetic sealing strip, and the ducted air system helps improve chamber uniformity and observation convenience. The cabinet uses a stainless-steel chamber with rounded corners, removable shelves, a magnetic door seal and hot-cold air ducts, with an internal working room of 500 x 550 x 900 mm and an external footprint of 740 x 705 x 1560 mm. That combination of chamber size, shell build and liner material makes the unit easier to place, clean and use in routine laboratory work.

The series combines temperature and humidity control with memory and self-diagnosis functions so that the chamber can keep operating reliably after power interruptions or alarms. The stated input power is 800 W, and the timer range is 0 to 9999 min. It is well suited to the day-to-day work listed above, including culture, incubation, climate simulation or illuminated growth tasks, depending on the family.

Performance Features

Self-diagnosis and over-temperature self-limiting help protect samples and reduce running risk. This supports more reliable day-to-day chamber use.
Power-off memory preserves settings after interruptions and supports continuous workflows. This helps preserve operation settings after power interruptions.
The embedded screen and multi-parameter display make operation and status review straightforward. This supports more reliable day-to-day chamber use.
The magnetic outer door seal and tempered-glass inner door improve sealing and observation. This improves observation and helps reduce heat loss while checking samples.
Hot and cold air ducts help improve chamber circulation and temperature uniformity. This helps improve chamber circulation and temperature uniformity.
Programmable temperature, humidity and time control suits repeatable laboratory methods. This is useful for cultivation, conditioning and biological workflows that need moisture control.

APPLICATION SCOPE: Suitable for environmental protection, epidemic prevention, veterinary research, drug testing, aquatic research, BOD measurement, microbial culture, plant cultivation and breeding tests in universities, laboratories, research institutes and quality-control environments that need controlled chamber performance.

HANDLING: Keep the chamber upright, maintain clear air paths and allow sufficient service space around the unit for ventilation and maintenance. Every unit is shipped with reinforced packaging for transport safety; keep the unit upright during unloading and positioning.

IMPORTANT NOTICE: When the set temperature is 10 C or below, ambient temperature should not exceed 26 C. When the set temperature is above 40 C, the humidity setpoint is normally kept below 80% to protect service life. Any quoted amount refers to the chamber body only and does not include freight. Freight should be confirmed separately according to the delivery destination.

When the set temperature is 10°C or below, ambient temperature must not exceed 26°C. When the set temperature is above 40°C, the humidity setpoint should generally not exceed 80% to protect service life.

Temperature-Dependent Ambient Limit: At setpoints at or below 10°C, ambient room temperature must not exceed 26°C to maintain chamber stability.
High-Temperature Humidity Constraint: When the chamber is operating above 40°C, the humidity setpoint must be kept at or below 80% to prevent damage to the system.

HowTo

Position the chamber upright with clear air paths and sufficient service space for ventilation and maintenance. Program temperature, humidity, and time parameters using the LCD controller for repeatable workflows.

Required Equipment: Temperature and Humidity Chamber (247 L, 5 to 50°C)

Position the Chamber
Place the unit upright on a level surface with at least 15 cm of clearance on all sides for airflow and maintenance access.
Connect Power Supply
Connect the chamber to a grounded AC 220 V, 50 Hz outlet rated for 800 W continuous load.
Set Temperature Conditions
Enter the desired temperature setpoint (5 to 50°C) via the LCD controller, ensuring ambient temperature does not exceed 26°C if setpoint is 10°C or below.
Configure Humidity Parameters
Program the humidity setpoint (50% to 90% RH) on the LCD, keeping it at or below 80% if the temperature is above 40°C.
Verify Chamber Stability
Allow the chamber to stabilize for 30 minutes and confirm the LCD display shows steady temperature and humidity within specified fluctuation limits.

FAQ

What are the operational constraints for temperature and humidity setpoints in the Atomfair AF-HSP250BE 247 L chamber?

The chamber’s humidity control range is 50%RH to 90%RH, but when the set temperature exceeds 40 °C, the humidity setpoint should generally not exceed 80%RH to protect equipment service life. Additionally, when the set temperature is 10 °C or below, the ambient room temperature must not exceed 26 °C. These constraints are explicitly stated in the technical specifications and important notice.

Is the Atomfair AF-HSP250BE suitable for BOD measurement and microbial culture?

Yes, the product description lists BOD measurement and microbial culture as intended applications, along with environmental protection, veterinary research, drug testing, aquatic research, plant cultivation, and breeding tests. The 247 L capacity, 304 stainless steel interior, programmable LCD controller, and ducted air circulation system support these workflows by providing steady, repeatable temperature and humidity conditions.

What power and installation requirements are needed for the Atomfair AF-HSP250BE humidity chamber?

The chamber requires an AC 220 V, 50 Hz power supply with an input of 800 W. Its external dimensions are 740 × 705 × 1560 mm and net weight is 106.5 kg. The unit must be kept upright during handling and positioning, with clear air paths and sufficient service space around the unit for ventilation and maintenance. Shipping uses reinforced packaging, and freight is quoted separately.

Assessment

The Temperature and Humidity Chamber, 247 L (AF-HSP250BE) provides 247 L of usable space with temperature control from 5 to 50°C and humidity from 50% to 90%RH, featuring a 304 stainless steel chamber, self-diagnosis, and power-off memory. However, operation below 10°C requires ambient temperature ≤26°C, and when set above 40°C, humidity setpoints must be kept below 80% to protect service life.

Positive

Self-diagnosis and over-temperature protection: Built-in self-diagnosis and over-temperature self-limiting functions help protect samples and reduce operational risk, supporting reliable day-to-day chamber use.
Power-off memory for continuous workflows: Power-off memory preserves temperature, humidity, and time settings after interruptions, allowing uninterrupted operation and repeatable experimental conditions.

Trade-offs

Low-temperature ambient constraint: When set temperature is 10°C or below, ambient temperature must not exceed 26°C, limiting placement in unconditioned spaces or hot labs.
High-temperature humidity limitation: When set temperature is above 40°C, humidity setpoints should generally not exceed 80% to protect service life, restricting combined high-temperature/high-humidity tests.
