Open Top Chambers (OTC)

Precision Environmental Microclimate Control & Gas Regulation

The primary goal of our Open Top Chambers (OTCs) is to precisely manage and regulate CO2 levels, temperature, and humidity inside the chambers. This allows researchers to conduct high-fidelity investigations on how crops, trees, and plant ecosystems react to elevated carbon dioxide and other greenhouse gas concentrations under realistic field conditions.

Highly customizable solutions developed in collaboration with top agricultural universities. Category: Research & Environment | Availability: Custom Tailored.

Product Overview

Product Overview

Open Top Chambers are a widely recognized, cost-effective method for studying the impact of rising greenhouse gases, ambient temperatures, and humidity gradients on crop growth kinetics, transpiration rates, and final crop yields. Our advanced automated OTC systems feed gases precisely using standard CO2 cylinder manifolds, high-performance piping, micro-solenoid manifolds, and state-of-the-art gas analyzers.

All chambers are controlled via a central, PC-linked Supervisory Control and Data Acquisition (SCADA) network. Our robust STM32-based hardware architecture guarantees accurate closed-loop control and logging of all critical agricultural variables.
