Instrument Introduction:

The fruit and vegetable respiration tester is specifically designed for measuring and analyzing the respiratory intensity of fruits and vegetables under storage conditions such as room temperature, refrigerated storage, controlled atmosphere storage, and supermarket refrigerators. The feature of this instrument is that it can adapt to the characteristics of fruits and vegetables

Choosing different volumes of breathing chambers based on their size accelerates the balance and measurement time; It can display the CO2 concentration, O2 concentration, temperature, and humidity of the breathing room simultaneously. This instrument has the characteristics of multifunctionality, high precision, speed, efficiency, and convenience, and is very suitable for respiratory measurement of various fruits and vegetables in schools and research institutes such as food, horticulture, fruits, vegetables, and foreign trade.

[Basic Product Configuration]

Accessory name and quantity

One host

Three sets of breathing rooms

One power cord

One card reader

One storage card

Two trachea

One software CD

One instrument box

General testing process:

1. Place the fruit or vegetable to be tested into the corresponding breathing chamber and tighten the lid of the breathing chamber

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

3. Set the collection time interval and enter the username to enter data measurement, then 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 host power, 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
