The working principle and operation method of moisture detector

First, the working principle‍

Edible bacteria moisture meter, also known as halogen rapid moisture analyzer, designed by the principle of pyrolysis weight, is a new type of rapid food industry moisture detection instrument. While measuring the weight of the sample, the instrument uses a circular tube halogen heating method to quickly dry the sample. During the drying process, the moisture meter continuously measures and instantly displays the % moisture content lost by the sample. After the drying process is completed, the final measured moisture is obtained. The content value is displayed as a lock. Compared with the international oven heating method, halogen heating can dry the sample evenly and quickly at high temperature, the surface of the sample is not easily damaged, and the detection result has good consistency with the national standard oven method, and has the alternative, and the detection efficiency is far high. In the oven method. The general sample can be measured in just a few minutes.

Second, the product features ‍

1. The halogen lamp is heated evenly and scientifically;

2, the detection speed is fast, only a few minutes;

3, small size and light weight;

4, fully automatic testing, a wide range of uses;

5. Simple operation and accurate measurement;

6. The display part is displayed by red digital tube (7 parameters: moisture value, sample weight initial value, final value, measurement time, initial temperature value, final value, discrimination time);

7, with a printer, computer connection function (optional accessories).

Third, the operation method

(1) Preparation work‍

1. The instrument is placed on the working platform of the laboratory smoothly, and the bottom protection weighing screw is loosened by 2-3mm;

2. Open the heating system, install the weighing components, and place them into the tripod, bracket, and sample tray in turn;

3. Turn on the power, turn on the power switch at the back of the instrument, and the instrument starts self-test and resets to zero;

4. The actual weight window of the instrument is displayed: 0.00. Put a 20g weight and display 20.00g. If the display is not 20.00, remove the weight, (set to zero), press (calibration), the weight window displays -20-, put the weight, the instrument automatically calibrates. After the calibration is completed, the instrument displays 20.00g and removes the weight.

(2) Sample testing‍

1. Set the temperature;

2. Sampling: If the sample stack is together, take out the sample tray and flatten it. Do not lay the sample directly on the instrument with your hand or sample spoon. If there are large particle samples, please crush or take out (the sample must be even);

3, close the heating system (heating tube)

4, the weighing is stable, press the (↑) button, press the (test) button, the instrument is heated. (Do not put the hand on the heating cylinder during the test to avoid burns)

5. Press the (display) button after recording to record the data.

four,

1. Use environment: no dust, no wind, dry, no vibration, no magnetic field around;

2. The instrument is kept clean;

3, the weighing system can not be overloaded or gravity pressure, must pay attention;

4. If the infrared product, the heating lamp is dirty, wipe it regularly;

5. Turn off the small compartment on the right side of the temperature setting.

Fifth, the main parameters‍

1. Moisture measurement range (%): 0.01-100

2, moisture measurement time: only a few minutes

3. Determination of sample weight (g): 0.5-60

4, the maximum weighing (g): 60

5, water content readability (%): 0.01

6, temperature indication range (°C): start -180

7. Dimensions (mm): 380×205×325

8, net weight: 3.7kg
