Feature: 1. Measurement Performance: This grain moisture tester is accurate, fast and easy to measure, with LCD display and bright and clear test results. 2. Intelligent Weighing: Automatic weighing, temperature compensation, moisture average calculation, capacity conversion, multi point calibration, error correction. Support more than 20 different kinds of grain moisture testing standards, measuring the weight and temperature, etc. 3. Power Supply and Consumption: Dual use AC and DC power supply, either one of the power supply, intelligent hibernation function, low power consumption, energy saving. 4. Anti Slip Pad Design: The bottom has a non slip foot pad design, can be more smoothly placed on the desktop, easy not to fall damage. 5. Applicable Occasion: Adopting the principle of frequency conversion capacitance measurement for grain testing, the instrument is mainly applicable to the inspection and measurement of grain acquisition and storage, and can also be used for professional teaching in colleges and universities.

Package List: 1 x Moisture Meter4 x Accessories1 x Manual1 x Adapter1 x Weight1 x Cleaning Brush Note: 1. The instrument is a accuracy electronic product, must be lightly handled, shockproof, moisture‑proof, and must be placed horizontally when used and stored, and should be cleaned and maintained regularly. 2. The battery should be removed when the instrument is not used for a long time or transported. 3. The product "balance calibration", "error correction" and "calibration" before, must empty the residue in the instrument. 4. To ensure the accuracy of the instrument, please carry out "balance calibration" before each measurement. 5. When measuring the moisture value of large particles, please use the "average moisture measurement method" to determine. 6. Do not turn off the instrument during "error correction" and "calibration", otherwise the measurement data will be invalid. 7. The instrument "calibration" must be set in order of low, medium and high moisture value. 8. When using the instrument, only one power supply can be connected, do not use the battery and AC power supply at the same time. 9. When the product storage should be cut off the power or remove the battery, and protected by dust cover, placed in a cool, dry place and stored horizontally.
