Easy and Efficient Carbon and Moisture Determination
812 Series Carbon/Moisture Determinators
This next-generation multiphase analyzer provides enhanced sensitivity so that even low-level carbon and moisture can be detected, ensuring strict specifications are met with confidence. Its flexible programming makes it reliable for a wide range of applications, including testing surface carbon on inorganic materials, detecting moisture in welds, and quantifying total organic carbon in soil. Faster heating and cooling times allow operators to move through more samples in less time.
More flexible, faster, and more convenient than previous generations, this new and improved carbon and moisture determinator is a reliable and worthwhile addition to labs looking to increase their overall safety, cleanliness, and throughput.
Why Choose the LECO 812 Series?
Speed and Efficiency
Reduce Your Wait Time Between Samples
With an efficiently designed horizontal furnace, the 812 Series boasts excellent temperature control, allowing for staged heating and active cooling. Compared with previous generations, it performs up to 50% faster temperature ramp-ups and 30% faster cool-downs, resulting in less waiting time to begin new analyses.
Using thermal differentiation, carbon and moisture can be measured simultaneously, increasing efficiency and allowing you to do more with your samples.
812 series offers front and side access
Superior Usability
Designed with the Operator in Mind
The 812 Series was engineered to maximize uptime and simplify routine ownership. A thoughtfully designed chassis with both front- and side-access gives operators rapid access to critical service points, reducing maintenance time and minimizing disruptions to laboratory workflows. Combined with enhanced diagnostics, segmented leak checks, and simplified furnace tube connections, routine troubleshooting and service activities can be completed faster and with greater confidence.
Building on LECO’s Cornerstone platform, the 812 Series couples robust hardware with intuitive software to streamline daily operation. From calibration and method development to data review and reporting, Cornerstone software reduces training requirements and helps users work more efficiently. The result is a safer, more productive laboratory.

How the 812 Series Works
The CM812 analyzer determines carbon and moisture in a wide range of organic and inorganic materials using a programmable furnace that precisely controls temperature from near ambient to 1100 °C in either oxidizing (oxygen) or inert (nitrogen) atmospheres. Through configurable heating profiles and purge gases, the system selectively volatilizes or combusts different sample constituents, while an afterburner and oxidation catalyst ensure complete conversion to measurable gases.
Carbon and moisture are quantified by infrared detection of CO₂ and H₂O, and the resulting data allow users to differentiate and quantify multiple carbon and moisture fractions based on their volatilization or oxidation temperatures. This temperature-based approach enables direct characterization of complex samples without extensive sample preparation, providing both qualitative insight and quantitative results.
Features
Enhanced Sensitivity
Detect ultra-low levels of carbon and moisture with confidence. Improved infrared detection provides enhanced sensitivity and precision for demanding applications, including high-purity metals, powders, soils, waste, and welding materials.
Faster Throughput
Increase laboratory productivity with rapid heating, active cooling, and advanced furnace control. Up to 50% faster ramp-up rates and 30% faster cool-down times reduce cycle times and help labs process more samples per shift.
Thermal Differentiation Technology
Gain deeper insight into material composition through programmable temperature-controlled analysis. Different carbon and moisture fractions can be separated and quantified without the time-consuming acid digestion and hazardous chemical preparation required by many traditional methods.
Operator-Focused Design
Designed to simplify ownership and maximize uptime. Front- and side-access service points, enhanced diagnostics, and streamlined maintenance procedures make routine operation, troubleshooting, and service faster and more convenient.
Cornerstone Software
Optimize laboratory workflows with LECO’s intuitive Cornerstone software platform. Streamlined calibration, method development, diagnostics, and data management help reduce training requirements and improve daily productivity.
Application Versatility
One platform for a wide range of carbon and moisture analyses. From TOC, TIC, and ROC determination in soils and waste to residual hydrocarbons, surface carbon, welding consumables, and powder metal moisture, the 812 Series delivers flexible analytical capability across diverse industries.
100-Position Autoloader Option
Automates large analytical batches to increase throughput and reduce operator intervention.
