Product Features
Advanced Metal Condensation System
The nitrogen analyzer features a built-in refrigeration system that enables water-free condensation without the need for external tap water or a chiller. The condenser is constructed from corrosion-resistant titanium and equipped with a high-precision temperature sensor for real-time monitoring of condensation temperature. This design ensures complete, loss-free condensation of ammonia and water vapor, delivering stable and highly efficient performance. In addition, the compact integrated structure saves installation space and reduces water consumption by up to 99% compared with conventional instruments.
Fully Automated Operation for Efficient Experiments
Fully automated operation enables automatic addition of alkali, acid, and diluent, and the automatic execution of distillation and titration, cleaning, digestion tube emptying, solution level monitoring, over-temperature monitoring, and waste disposal. The system automatically performs result calculation, output, and printing, and supports two operating modes: distillation followed by titration, and simultaneous distillation and titration.
High-precision Syringe Pump Micro-controlled Titration System
The titration system adopts dynamic titration technology, enabling simultaneous distilation and titration while automatically adjusting the titration speed and volume according to the experimental progress,improving efficiency and enhancing testing accuracy. The instrument is equipped with a high-precision syringe pump titration system and comes standard with a 25 ml burette, with compatibility for 5 ml, 10 ml,35 ml and other burette sizes to meet different titration precision requirements.
Dual-layer Vacuum Insulation Structure Design
The steam generator is constructed from food-grade 304 stainless steel and features a dual-layer vacuum insulation structure. It integrates automatic thermal insulation with constant-temperature control and automatic liquid level monitoring. effectively reducing heat-up time and enabling instant steam generation.thereby ensuring efficient and convenient operation throughout the experimental process.
Equipped with a 10-inch Color Touchscreen and Android System for Enhanced Functionality
Equipped with a 10-inch color touchscreen and an Android-based operating system, the system supports Chinese and English user interfaces. It provides a rich set of functions with simple and intuitive operation.enabling real-time monitoring and display of the experimental process.
Cloud Service Functions
Supports Wi-Fi and other network connectivity options and can be integrated with LIMS (Laboratory Information Management Systems). Enables cloud-based data storage or local data download, with a storage capacity of more than 2,000,000 data records.
Rich Software Interface for Real-time Process Monitoring
The software interface provides comprehensive functionality and displays the entire titration process in real time through graphical curves. Data including color changes, titration volume, steam temperature, and condensation temperature are synchronously displayed in real time, offering a clear and intuitive overview.
Status Indicator Light for Real-time Instrument Status Feedback
The front panel of the instrument is equipped with a status indicator light, with different light colors providing real-time visual feedback of the instrument status, including standby, operation, and fault conditions.
Safety Compliant with FDA 21 CFR Part 11
Test results can be exported in XLS, XML, or PDF formats to accommodate various customer needs an dare fully compliant with FDA 21 CFR Part 11. The system incorporates a built-in, multi-level user access control with at least three permission levels, ensuring secure and fully traceable data management.
