1. Product Description:
Because any product will collide and vibrate during transportation, use, storage, and cause the product to be bad for a certain period of time, seriously affecting the use of the product and unnecessary economic losses. In order to avoid this happening, we must know the product early. Or the vibration-resistant life of the components in the product.
2. Technical parameters
1. Vibration table size L×W (cm): 30×30, 50×50, 75×75, 100×100
2, the size of the table body L × H × W (cm): vertical 30 × 20 × 30, 50 × 20 × 50, 75 × 20 × 75, 100 × 20 × 100
Horizontal 30 × 25 × 30, 50 × 25 × 50, 75 × 25 × 75, 100 × 25 × 100
3, vibration direction: vertical (up and down) / horizontal (front and rear left and right)
4, zui large test load KG: 100
5, FM function 1 ~ (600HZ, 5000HZ customer-defined) Any frequency must be in the frequency range (zui large acceleration <20g zui large amplitude <5mm)
6, sweep function 1 ~ (600HZ, 5000HZ customer custom): (upper limit frequency / lower limit frequency / time range) can be arbitrarily set the true standard to the sweep frequency
7, programmable function 1 ~ (600HZ, 5000HZ customer custom): 15 segments can be arbitrarily set (frequency / time) can be cycled
8, multiplier function (1 ~ 600HZ): 15 segments into multiples increase, 1. low frequency to high frequency 2. high frequency to low frequency 3. low frequency to high frequency and then to low frequency / can be recycled
9, logarithmic function 1 ~ (600HZ, 5000HZ customer-defined): 1. Down frequency to upper frequency 2. Up to down frequency 3. Down frequency to upper frequency to lower frequency -3 mode logarithm / recyclable
10, vibration machine power (KW): 2.2
11, amplitude (adjustable range mmp-p): 0 ~ 5mm
12, zui great acceleration: 20g
13, vibration waveform: sine wave
14, time control: any time can be set (seconds)
15, power supply voltage (V): 220 + 20%
16, zui high current (A): 5
17, full-featured computer control (optional): 485 communication interface if you want to connect to the computer for control, storage, recording, printing functions need to buy another interface card computer
18, precision: frequency can be displayed to 0.01Hz, precision 0.1Hz
19. Display amplitude acceleration (optional): If you need to see amplitude, acceleration, zui acceleration, accurate number, you need to purchase another measuring instrument.
20, zui large acceleration 20G (unit is g)
Zui large acceleration = 0.002 × f2 (frequency HZ) × D (amplitude p-pmm)
Example: 10HZzui large acceleration = 0.002 × 102 × 5 = 1G
Zui acceleration cannot be greater than 20G at any frequency
21. zui large amplitude 5mm
Zui large amplitude = 20 / (0.002 × f2)
Example: 100Hzzui large amplitude = 20 / (0.002 × 1002) = 1mm
The amplitude cannot be greater than 5mm at any frequency
22. Acceleration and amplitude conversion 1g=9.8m/s2
23. The higher the frequency, the smaller the amplitude. 3. Compliance with the standard: GB/2423 IEC68-2-6 (FC) JJG189-97 GB/T13309-91

A lot of nutrition researches and practices prove that the efficacy of mealworm protein is superior to plant and animal 
protein and has scientifically solved the defect of plant and animal protein.

In mealworm feed, there is less fiber content and rich trace elements, and the content of copper, iron, zinc, selenium is 
higher. In addition, the chlorine acid is more balanced, and containing lipids are soft fats and unsaturated fatty acid, 
which can be digested well and can be absorbed easily. 

Tests show that long-term consumption of mealworm protein feed can reduce the risk of animals, so as to reduce the 
medication costs. So it is the best choice of your pets.

Ingredients: 100% Dried Mealworm
