Grain Moisture Meter MD-7822 Grain Moisture Meter Grain Moisture Meter Dimensions 174 38 73 (main unit) (mm) Ambient temperature -1060 () Accuracy (1%Rh+0.5) Measuring range 2%30% Grain type Moisture Meter Model MD7822I. Overview This instrument is powerful and can measure the humidity and temperature of various grains. It is suitable for the allocation, acquisition, storage, processing and other work of packaged grains. It can quickly and accurately measure the moisture and temperature of grains during work. 2. Performance characteristics: * Microcomputer technology (CPU) is used to make the measurement more accurate * Automatic temperature compensation function * Large LCD display with backlight to ensure clear readings without parallax. * There is a special backlight switch to save batteries. * Powered by four AA batteries, it will automatically display when the battery voltage is lower than the specified value. * The structure is sturdy and exquisite, the whole machine uses durable and optimal electronic components, and the shell is made of lightweight and hard ABS plastic. It has beautiful appearance, is easy to carry and simple to use. *Testable grain types: wheat, rice, paddy, corn Three technical indicators Humidity measurement range: 2%~30% Maximum error: (1%RH0.5) Resolution: 0.5% Temperature measurement range: -10~60 (14~140) Maximum error: 2 (4) Resolution: 1/2 Use environment: Temperature: -10~40 (14~104) Humidity: 0~70%Rh Weight: The above weight includes the measuring probe and battery Size: 174 38 73 (host) 365 25 43 (measuring probe) IV. Operation instructions 1. Install the battery and press the button to turn on the meter. 2. Press the button to select the meter's measurement item: the moisture content of the grain being measured or the temperature at the probe location. When measuring the moisture content of the grain, the meter displays "XL.%", and when measuring the temperature at the probe location, the meter displays "1-". The meter can measure the moisture content of the grain by default when it is turned on. 3. Grain moisture measurement: After confirming that the meter can display the moisture content of grain, press the key to select the type of grain to be measured (the type is indicated by 1, 2, 3, and 4 on the screen, 1 for wheat, 2 for rice, 3 for rice, and 4 for corn), insert the probe into the grain to be measured, and the grain moisture measurement can be performed. The meter displays the moisture content of the grain to be measured. During the measurement process, if you press the key, "MAX" will be displayed on the screen, and the meter will enter the maximum value holding mode. Press the key again to exit this mode. In the maximum value holding 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 reads the hold button. Press the key for the first time to select the reading hold function (the display screen displays the symbol), and press the key again to cancel the function (the display screen does not display the symbol). 4. Temperature measurement: When the temperature of the probe location is selected, the meter can approximately display the temperature of the environment where the probe is located. At this time, press the Enter key to switch between Celsius and Fahrenheit (the meter displays Celsius by default). 5. After the measurement is completed, press the Stop key and the meter will enter standby mode. 6. Turn on/off the screen light
