precision lab oven specifications
The JBS202-2 precision lab oven boasts better temperature uniformity, which is with a specification of ±1.5%℃, significantly better than the common ±2.5%℃, ensuring a highly consistent temperature throughout the chamber.
Suitable for precision processes such as aging tests of electronic components, thermal stability testing of materials, pharmaceutical drying, and heat treatment of scientific research samples.
The lockable door, combined with a high-temperature resistant silicone sealing strip, enhances sealing and prevents heat loss and external interference.
The equipment has a compact structure, with dimensions of only 675×710×1025mm, saving space and suitable for various laboratory layouts.
Equipped with a paperless recorder, it facilitates real-time monitoring and data traceability, meeting the needs of quality management and auditing.
As a representative of Hoson Technology's precision temperature control equipment, the JBS202-2 provides customers with a reliable testing platform through its high uniformity, intelligent control, and user-friendly design.
Dimensions can be customized to your requirements.

FAQ
Q: How can I trust your capabilities?
A: We can provide you with videos and photos of our factory, showing you our actual production process and factory environment.
Q: Is the quality and after-sales service of this drying oven guaranteed?
A: Yes, it is. The equipment uses high-quality stainless steel and brand-name core components, adhering to the manufacturing standards of our large-scale non-standard projects. We offer a 12-month free warranty and lifetime technical support to ensure rapid response and peace of mind.
Q: How long does it typically take to ship a customized drying oven?
A: Usually 30-45 days. After the contract is signed, we will first provide you with 3D drawings for review. Only after your review and approval will we begin manufacturing the drying oven, ensuring the equipment perfectly meets your testing site requirements.
Q: What exactly do you mean by "precision" and "good uniformity"?
A: The core indicator is temperature uniformity better than ±2.5%℃. This means that the temperature is highly consistent throughout the chamber, ensuring the accuracy and reliability of data from the same batch of samples and avoiding misjudgments caused by temperature differences.
