IR vs TC Sensors in CO2 Incubators

In biological and medical research, CO2 incubators are crucial in maintaining optimal conditions for cell cultures. At the heart of these incubators lies a critical component: the CO2 sensor. This white paper delves into the two primary technologies used for CO2 measurement in incubators - Infrared (IR) and Thermal Conductivity (TC) sensors.

The document begins by explaining the importance of CO2 control in maintaining stable pH levels for cell growth. It then breaks down the fundamental principles behind IR and TC sensor technologies. IR sensors utilize the specific light absorption properties of CO2, while TC sensors measure changes in electrical resistance due to gas composition.

A key focus of the paper is comparing these two technologies in terms of accuracy, reliability, and cost-effectiveness. While more affordable upfront, TC sensors face challenges in maintaining accuracy when incubator doors are opened, potentially leading to significant downtime and inconsistent results. In contrast, IR sensors offer more consistent and reliable measurements, regardless of temperature and humidity fluctuations.

The paper goes beyond technical comparisons, offering practical insights for laboratory managers and researchers. It presents a compelling cost-benefit analysis, demonstrating how increased productivity and more reliable research outcomes can offset the initially higher cost of IR sensors.

The paper makes a strong case for IR sensor-equipped incubators for labs engaged in sensitive research or those looking to expand their capabilities. It argues that the long-term benefits of accuracy, reliability, and time savings outweigh the initial cost difference.

This white paper is an invaluable resource for laboratory professionals who are making decisions about incubator equipment. It provides the necessary information to make an informed choice between IR and TC sensor technologies, considering immediate budget constraints and long-term research quality and efficiency.

Whether setting up a new lab, upgrading existing equipment, or simply seeking to understand the technology behind your current incubators, this document offers clear, concise, and practical guidance. It empowers readers to make choices that best serve their research needs and organizational goals.
