【Case Background】Our client is a key materials science laboratory affiliated with a top-tier domestic university conducting cutting-edge research projects. The laboratory operates multiple high-sealing inert gas glove boxes filled with high-purity nitrogen and argon as shielding atmospheres, with core experimental conditions requiring stable long-term oxygen concentration control below 10 ppm inside chambers.

【Product Core Advantages】

The HT-TA025 trace oxygen transmitter is custom-designed for trace oxygen monitoring in sealed inert chambers, fitted with imported fuel cell sensor cores to perfectly meet long-term continuous monitoring demands of laboratory glove boxes:

1.Ultra-high Precision Trace Oxygen Detection

Optional measuring ranges: 0~10 ppm / 100 ppm / 1000 ppm O₂, with a resolution of 0.1 ppm. The accuracy reaches ≤±3% FS within the 0~10 ppm range. It delivers stable and drift-free readings under low-oxygen environments and accurately detects trace oxygen leakage at the ppm level.

2. Fast Response for Real-time Risk Control

The T90 response time is ≤60 seconds. It rapidly feeds back oxygen fluctuations caused by air intake through chamber doors or sealing leaks and supports threshold alarm linkage with the chamber purification unit.

3. KF40 Standard Flange for Non-destructive Glove Box Installation

Comes with standard KF40 vacuum flanges that directly connect to standard testing ports of glove boxes without modifying internal pipelines. Easy to disassemble and assemble; only the sensor core needs independent replacement, greatly cutting maintenance and consumable costs.

4. RS485 Signal Output Compatible with Automation Systems

Adopts RS485 communication protocol, which can be synchronously connected to local glove box controllers and laboratory upper computers. It continuously stores oxygen content data 24/7 to meet the data archiving requirements of scientific research.

【On-site Application】

After 6 months of continuous and stable equipment operation, the laboratory issued an official usage report with the following core improvements: 

1. Sharply higher experiment success rate and drastically reduced consumable loss

Accurate and stable low-oxygen monitoring enables long-term atmosphere control inside the chamber, almost eliminating scrapping incidents of active materials due to oxidation. The experiment success rate rose from 62% before renovation to 96%, saving more than 30,000 RMB per year on precious metal and organic reagent consumables.

2.Rapid locations of tiny leaks and improved glove box maintenance efficiency

The transmitter can capture minimal oxygen leakage at ppm concentrations, allowing lab staff to quickly identify sealing defects including door gaskets, pipeline joints and airlock valves. Man-hours spent on glove box leak detection and maintenance are reduced by 70%.

3. Lower maintenance costs fitting laboratory budgets

Annual maintenance costs are cut by 50%. It features a long calibration cycle and user-friendly operation, enabling self-calibration by laboratory personnel.

【Customer Feedback】

 Laboratory Equipment Manager’s comment: “The original monitoring device built into our glove boxes provided inaccurate readings, leading to the failure of multiple critical experiments. After switching to the HT-TA025, it delivers stable and sensitive measurements in low-oxygen zones. The flange installation requires no major equipment retrofitting, and data can be directly transmitted to our lab system. The supporting technical service responds promptly. It fully satisfies our strict monitoring requirements for oxygen-free environments in cutting-edge materials research. Our research groups and university-industry pilot platforms will continue purchasing this product in the future.”
