Apex Instruments, a leading innovator in air monitoring equipment, is proud to announce the launch of the STM-6000 Automated Mercury Sampling Console. This cutting-edge console is designed to streamline and optimize mercury sampling in industrial applications. By automating critical processes such as data acquisition, sample flow adjustments, leak checks, and calibrations, the STM-6000 ensures precise, efficient, and fully compliant sampling in line with EPA PS 12B and Method 30B standards.
The STM-6000 replaces Apex’s first generation workhorse, the XC-6000. In fact, the new STM-6000 is designed to be a direct, plug-and-play replacement for current owners. Apex offers optional installation and service contracts to simplify operation and ownership.
The STM-6000 stands apart from competing products with its seamless integration of automation, user-friendly software, and real-time data displays. Tailored to meet the unique needs of the stack tester, the system allows operators to focus on results, not manual operations. With an intuitive interface, the STM-6000 simplifies complex workflows and offers enhanced accuracy and reliability in environmental monitoring.
Key Differentiators of the STM-6000:
- Comprehensive Automation: The STM-6000 automates essential tasks like sample flow adjustments, leak checks, temperature control, and calibration, reducing human error and ensuring compliance with strict regulatory standards.
- Seamless Data Acquisition & Transfer: Data from the system is easily captured and transferred to a Windows-based PC via Ethernet. The system’s real-time data display and remote monitoring capability through Modbus connectivity allow for continuous oversight and instant access to critical information from any location.
- Customizable & Flexible Configuration: The STM-6000 can be configured to suit various operational needs with options that include a standard 19” rack mount, an adaptable climate-controlled or weatherproof cabinet enclosure, or wall mount options offering versatility across different environments.
- Ease of Maintenance & Serviceability: Built with easy access to internal components, the STM-6000 is designed for quick serviceability in the field. It features drawer slides for convenient maintenance access, ensuring minimal downtime.

- High-Performance Sampling Components: The system is equipped with a positive displacement dry gas meter, double-headed sample pumps, stainless steel sample manifolds, and mass flow sensors for precise and reliable sample extraction. With a maintenance-free brushless motor and an extended operational lifespan of 10,000 hours (MTBF), the STM-6000 is engineered for durability.
- Advanced Data Security: The STM-6000 offers high-level security with 256-bit encryption (optional) for data storage, ensuring that sensitive sampling data remains safe and secure.
- Real-Time Monitoring & Remote Access: With built-in communications capabilities including Ethernet, USB, and optional TCP/IP Modbus, users can remotely monitor and control the console, providing greater flexibility and reducing the need for on-site presence.
With its unrivaled combination of automation, precision, and ease of use, the STM-6000, represents the future of automated environmental monitoring, offering industries greater accuracy, reduced operational complexity, and enhanced compliance.
