Fruit and vegetable respiration tester

Instrument Introduction:

The fruit and vegetable respiration tester is specifically used for measuring and analyzing the respiratory intensity of fruits and vegetables under storage conditions such as room temperature, cold storage, controlled atmosphere storage, and supermarket refrigerators. The characteristic of this instrument is that it can select different volumes of breathing chambers based on the size of fruits and vegetables, accelerating balance and measurement time; It can simultaneously display the CO2 concentration, O2 concentration, temperature, and humidity of the breathing chamber. This instrument has the characteristics of multifunctional, high-precision, fast, efficient, and convenient, and is very suitable for respiratory measurement of various fruits and vegetables in various schools and research institutes such as food, horticulture, fruits, vegetables, and foreign trade.

[Basic Product Configuration]

Name and quantity of accessories

One host

Three sets of breathing chambers

One power cord

One card reader

One storage card

Two tracheal tubes

One software CD

One instrument box

General testing process:

1. Put the tested fruit or vegetable into the corresponding breathing chamber and tighten the lid of the breathing chamber

2. Connect the main unit to the breathing chamber using a trachea, connect the main unit to the power supply, and power on the main unit

3. Set the collection time interval and enter the username to enter data measurement. Turn on the air pump for preheating

After preheating for about 30 minutes, press the "Confirm" button to start automatically recording data changes

5. After the test is completed, disconnect the power supply of the host, remove the SD card, and import the data into the computer

6. Input the recorded data into the respiratory intensity calculation software, calculate and save the results
