DB510-DB115 Humidity and Temperature Sensor

The Golden Combination for Precise Temperature & Humidity Control in Incubators

A biotech enterprise specializing in the R&D and production of probiotics and microbial agents relies heavily on professional incubators for its core microbial culture process, which demands strict temperature and humidity stability: the temperature must be precisely controlled at 35±0.5℃, and the relative humidity maintained at 60±5% RH. Real-time data monitoring is also required to ensure strain activity.

Previously, the enterprise’s traditional temperature and humidity monitoring equipment had obvious shortcomings: the large-sized monitoring probe could not be embedded in the compact internal space of the incubator and had to be installed externally, resulting in a measurement deviation of over ±1℃ from the actual environment inside the chamber; without real-time display, staff had to frequently open the incubator for checks, which disrupted the internal temperature and humidity balance and made it impossible to detect abnormalities in a timely manner; additionally, data could not be automatically recorded, failing to meet the requirements for production compliance traceability. Multiple batch culture failures caused by temperature and humidity fluctuations resulted in heavy losses.

To solve this problem, the enterprise adopted DABECO’s combined solution of the DB115 temperature and humidity probe and the DB510 monitoring instrument. Their synergistic advantages perfectly meet the needs of the incubator scenario:

The DB115 features an industrial flame-retardant plastic housing and a compact size, which fits into tight installation spaces. It can be directly embedded in the interlayer or corner inside the incubator, eliminating the measurement deviation caused by external installation. At 25℃, it achieves a precision of ±2% RH (humidity) and ±0.2℃ (temperature), with a measurement range of -20~80℃ and 0~100% RH, fully matching the enterprise’s culture requirements of constant temperature at 35℃ and constant humidity at 60% RH.
Meanwhile, the probe supports an I2C digital interface and adopts a low-power design (supply current ≤15mA, voltage 2.15-5.5V), eliminating the need for frequent power replacement. Its industrial plastic material is resistant to slight dust, adapting to the clean but non-strongly corrosive environment inside the incubator.

As a supporting monitoring terminal, the DB510 instrument offers three core values:
Dual-Line LCD Real-Time Display: Installed outside the incubator, it can simultaneously display the temperature and humidity data transmitted by the DB115. Staff can intuitively grasp the internal environment without opening the incubator, avoiding temperature and humidity fluctuations caused by frequent opening.

Multi-Interface Data Transmission: Supporting 4-20mA analog output and RS485 digital output (standard Modbus RTU protocol), it can be directly connected to the enterprise’s laboratory monitoring system to realize automatic recording and storage of temperature and humidity data, meeting the requirements for production compliance traceability. When data exceeds the preset threshold (e.g., temperature >35.5℃ or <34.5℃), the system can automatically trigger an alarm.

Strong Compatibility with External Probes: It accurately matches the signal transmission of the DB115, ensuring no data delay or drift.

Application Results
Since the deployment of this combined solution, the temperature and humidity control capability of the enterprise’s incubators has been significantly improved:
Data Precision and Stability: The measurement deviation of temperature and humidity inside the chamber has been reduced to ±0.3℃ and ±1.5% RH, far exceeding the previous monitoring level. The qualification rate of probiotic strain activity has increased from 82% to 99.5%, and there have been no more batch failures caused by temperature and humidity fluctuations.
