How It Works
The incubator operates through integrated temperature and humidity control systems working in coordination to maintain precise environmental conditions. The PT100 temperature sensor provides accurate measurement with 0.1°C resolution, feeding data to the control system that manages both heating and cooling functions. Stainless steel heating elements distribute heat uniformly throughout the chamber, while R134a refrigerant enables cooling when ambient conditions exceed the setpoint.
Humidity control is achieved through built-in steam humidification, which introduces water vapor into the chamber atmosphere to maintain the desired relative humidity levels. The system continuously monitors both temperature and humidity, making real-time adjustments to maintain setpoints within specified tolerances. Air circulation ensures uniform distribution of temperature and humidity throughout the working volume.
The control algorithm maintains temperature uniformity within ±2°C at 37°C and humidity fluctuation of ≤±8% RH in the operational range, providing stable conditions for temperature and humidity-sensitive applications requiring precise environmental control.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Temperature Range | 0-60°C with PT100 sensing | Basic models often limited to 15-50°C range | Wider temperature range accommodates refrigerated storage and elevated temperature testing in a single unit. |
| Humidity Control Method | Built-in steam humidification system | Many units require external water connections or pan evaporation | Self-contained humidification simplifies installation and reduces contamination risk from external water sources. |
| Temperature Precision | 0.1°C with ±1°C fluctuation at 37°C | Entry-level models typically offer ±2-3°C control | Higher precision enables tighter process control for temperature-sensitive applications and regulatory compliance. |
| Sensor Technology | PT100 resistance temperature sensor | Basic thermistors or thermocouples in lower-end units | PT100 sensors provide superior long-term stability and accuracy for critical temperature monitoring applications. |
| Humidity Range | 50-90% RH with 1.0% RH precision | Limited humidity control or wider tolerance ranges | Precise humidity control supports applications requiring specific relative humidity conditions for sample integrity. |
| Refrigeration System | R134a refrigerant cooling to 0°C | Many units lack cooling capability below ambient | Active cooling extends application range for low-temperature storage and conditioning protocols. |
The BJPX-HTB combines precise temperature control using PT100 sensing with integrated steam humidification in a self-contained unit. The system provides both heating and cooling capability across a wide temperature range with tight control tolerances, suitable for applications requiring documented environmental stability.
Practical Tips
Place calibrated reference sensors at multiple locations within the chamber to verify temperature and humidity uniformity during qualification.
Why: Spatial mapping ensures the entire working volume meets specification requirements.
Clean and refill the water reservoir weekly with fresh distilled water to prevent microbial growth and mineral deposits.
Why: Fresh water maintains humidification system performance and prevents contamination of the chamber atmosphere.
Allow the chamber to stabilize for at least 30 minutes at setpoint before loading critical samples or beginning time-sensitive experiments.
Why: Equilibration time ensures uniform conditions throughout the chamber volume for consistent results.
If humidity levels drift low, check the water reservoir level and ensure the humidification system is operating properly.
Why: Low water levels or system malfunctions directly impact humidity control performance.
Monitor and document both temperature and humidity continuously during critical experiments rather than relying solely on setpoint values.
Why: Continuous monitoring provides evidence of actual conditions and helps identify any deviations from specifications.
Ensure adequate ventilation around the unit and avoid blocking air vents to prevent overheating of the refrigeration system.
Why: Proper ventilation maintains system efficiency and prevents thermal damage to internal components.
Use perforated shelving or sample holders that allow air circulation around samples for uniform temperature distribution.
Why: Airflow restriction can create temperature gradients and affect the uniformity specifications.
Inspect door seals regularly and clean with mild detergent to maintain proper sealing and prevent condition drift.
Why: Compromised door seals allow air exchange that affects temperature and humidity stability.
