Product Introduction

The FS-3080B Fruit and Vegetable Respiration Tester is an analytical instrument designed to monitor respiratory gas exchange and environmental conditions in fruits and vegetables. By measuring carbon dioxide (CO₂), oxygen (O₂), temperature, and humidity, it helps users evaluate produce respiration characteristics and support postharvest quality management.

The instrument combines infrared CO₂ detection with electrochemical oxygen measurement, providing key gas concentration data for research, storage evaluation, and agricultural quality control. A 3.5-inch TFT true-color LCD offers a clear interface, while the built-in 16 GB memory supports convenient data storage and retrieval.

With automatic result calculation, adjustable gas flow, and USB connectivity for direct data export, the FS-3080B simplifies measurement workflows and helps users organize test results for further analysis. Its applications include postharvest research, fruit and vegetable storage studies, agricultural laboratories, and food quality assessment.

Working Principle

The FS-3080B Fruit and Vegetable Respiration Tester evaluates produce respiration by measuring changes in gas composition and relevant environmental parameters.

Carbon dioxide measurement: The instrument uses infrared detection to measure CO₂ concentration. Carbon dioxide absorbs infrared radiation at characteristic wavelengths, and the detector analyzes the absorption signal to determine gas concentration.

Oxygen measurement: An electrochemical sensor measures oxygen concentration through a chemical reaction that generates an electrical signal related to the oxygen level.

Temperature and humidity measurement: Integrated sensing components measure temperature and relative humidity, providing additional information about the conditions under which the produce is tested.

During operation, gas flow is controlled using the instrument's miniature flow meter. The measured parameters are displayed and processed automatically, and the results can be stored internally or exported through USB for subsequent analysis.

By comparing CO₂ and O₂ measurements over time under controlled conditions, users can study respiration patterns and evaluate how storage conditions affect the physiological activity of fruits and vegetables.
