Indirect Gas Calorimetry
The most accurate and reliable respirometry system measures the animal’s Oxygen consumption and Carbon Dioxide production to calculate key metabolic parameters, including the Respiratory Exchange Ratio and Energy Expenditure.
CaloMax HS — The Breakthrough in Indirect Calorimetry for Mice and Rats
CaloMax HS is our latest innovation — a complete re-engineering of rodent indirect calorimetry from the inside out.
Built on a flexible modular architecture, it integrates all critical components into a compact, intelligent system designed for long-term stability, precision, and effortless operation.
At its core lies a newly developed Multi-Sensor Board that unites all gas analyzers — O₂, CO₂, ¹³C, CH₄, and H₂ — within a single coordinated unit.
This short-path configuration minimizes signal delay and ensures fast, synchronized response across all parameters.
Combined with intelligent gas-flow control and optimized chamber integration, CaloMax HS delivers highly accurate metabolic data with minimal noise and exceptional reproducibility.
An embedded Intelligent Diagnostic System continuously monitors hardware and sensor performance, communicating with the control software in real time to predict maintenance needs and prevent downtime.
Together with Ethernet-based communication, simplified cable management, and a robust air-conditioning and pumping system, CaloMax HS defines a new generation of smart, durable, and efficient calorimetry solutions for metabolic research.
