Digital Grain Moisture Meter 2%-30% Humidity Tester Detector Instrument Wheat Corn Rice Moisture Probe Hygrometer Measure Tools Description:This instrument is powerful and can measure a variety of grain halves and temperature. It is suitable for the allocation, purchase, storage, and proceing of packaged grains. It can quickly and accurately measure the moisture and temperature of grains during work. Using microcomputer technology (CPU) to make the measurement more accurate With automatic temperature compensation function The large-screen LCD display with backlighting ensures clear readings and no parallax. Special backlight control switch, which is convenient for saving battery. 9V battery to supply power. When the battery voltage reaches the specified value, it will automatically prompt. The structure is sturdy and exquisite, the whole machine adopts durable repairing electronic components, beautiful in appearance, easy to carry, and simple to operate. Measurable food types:wheat, rice, rice, corn Specification:Power supply:1*9V (6F622) battery (not included) Moisture measurement range:2%~30% Maximum error:(1%Rh+0.5) Resolution:0.5% Temperature measurement range:-10~60 Maximum error:2 (4) Resolution:1/4 Operating temperature and humidity:Temperature:-10~60 Humidity:0~70%Rh Material:ABS+metal Size:140*70*30mm Operating Instruction:1. Install the battery and pre the button to turn on. (battery prepare by yourself) 2. Pre the button to select the test item of the meter:the moisture content of the measured grain or the temperature of the environment where the probe is located. When measuring the moisture content of grain, the meter will display ''XX.X%'', and when measuring the temperature at the position of the probe, the meter will display ''XX.X''. By default, the meter is in the state of measuring the moisture content of the grain when it is turned on. 3. Measuring grain moisture content:confirm that the meter is in the state of displaying grain moisture content, pre the button to select the type of grain to be measured (the type display screens 1, 2, 3, 4 represent, 1 is wheat, 2 is rice, 3 is rice, 4 For corn), insert the probe into the grain to be measured to measure the moisture content of the grain. At this time, the meter displays the moisture content of several grains to be measured. During the measurement, if you pre the key, "MAX" is displayed on the screen, and the meter enters the maximum holding mode. Pre the key again to exit this mode. In the maximum hold mode, the display will only be updated when the measured value is greater than the current display value, otherwise it will not be updated. The side button is the value hold key. Pre it for the first time to select the value hold function (the display shows the symbol), and pre it again to cancel the function (the display no longer displays the symbol). 4. Measuring temperature:When selecting the temperature of the position where the measuring probe is located, the meter can roughly display the temperature of the environment where the probe is located. At this time, pre to switch between Celsius and Fahrenheit (the meter displays Celsius by default). 5. After the measurement is completed, pre shutdown and the meter will enter the sleep state. 6. Pre the "" key to turn on/off the display backlight. Tips:1. This instrument is a high-resistance instrument, and each part has good insulation. When using and storing, pay attention to moisture and dust, keep it dry and clean, so as not to affect the accuracy of the measurement. 2. When using a measuring probe to measure moisture, the grain preure has a greater influence on the measurement. Generally, when the sacks are placed in a single layer, the measurement is the most accurate. When placed in multiple layers, the lower grain preure is higher and the index is higher. It should be corrected according to the accumulated experience in use, and the grain preure influence value is subtracted to make the reading more accurate. The greater the grain moisture, the greater the impact on the measurement of grain preure. If the moisture content is below 13%, the grain preure has little effect on the measurement. 3. When measuring multi-layered grains with the measuring probe, the influence of grain preure is mainly reduced based on the experience accumulated by oneself. Even if the high-moisture packaged grain samples placed in multiple layers are measured, the test can still be accurate (within 0.5%) ), but if you must calculate the measurement accuracy and the relationship between the grain preure, the grain bag is placed in a single layer, and the measurement probe is inserted from the top to the bottom for the measurement. You can also compare the data measured by the single layer and multi-layer placement.
