Soil moisture meter(20cm probe)

I. Introduction HY8FD-T1 soil moisture meter is introducted from foreign advanced technology company  and first launched in the domestic high-performance, digital moisture measuring instruments. Principle of using high-frequency devices, digital display, with a number of stalls used to measure various soil, moisture. The wide range of instruments to measure moisture, high accuracy, shows clearly the rapid measurement of stable performance, reliable indicators, and small size, light weight, portable and rapid detection of the scene, simple to use. Is the ideal instrument for testing soil moisture. main features 1, introducing advanced foreign technology, imported chips, the domestic assembly.
2, the unique sensor design and production methods are beyond the normal ability to penetrate.
3, proprietary sensor technology, the work of a wide range of measurement can be inserted quickly displayed.
4, portable instrument case for the proprietary design.
5, compact instrument design, compact structure, stable performance and excellent quality. Third, the working environment Temperature: -5 ℃ ~ +50 ℃
Humidity: ≤ 85% RH how to work The instrument is the introduction of foreign advanced technology uses high-frequency theory, that is, within the instrument has a natural frequency, measured in different materials, pass through the sensor into the machine a different frequency, the difference between two frequency comparison, the current through the frequency converter into a digital display. Fifth, technical performance 1, measurement range of water

: 0% ~ 80%
2, use of the environment: -5 ℃ ~ +50 ℃
3, shows: 3 1/2LCD LCD display
4, Resolution: 0.1%
5, size: 160 × 60 × 27mm
6, weight: 0.3kg
7, power supply: 9V battery (6F22)
6, for use Moisture meter for the contact measuring instruments, sensors measuring the assumption that the sensitive part (more than 10cm in front of less than) full contact with the measured object, in general, the sensor probe into sensitive areas should be measured as an internal object in order to reduce measurement error. If measured around the metal object will lead to inaccurate measurements, and called for sensors sensitive parts of the insert should not be within 20cm around the metals. 7, steps of using 1, handheld devices, will lead the two ends were inserted into the body outlet and the sensor, will go to file switch to "ON" file (ON to open, OFF is off), LCD screen display ± 00.5, if not within its scope should be slow to adjust to zero knob "ZERO", so that figures can be within the ± 00.5.
2, the probe measured object, the number of cases that stable, indicating the number of water value for the measured object.
3, numerical validation: When the measured values have errors, please turn dial. Example: the actual object under test is 15% water, with 7 stalls tests showed values of 14%, Rotate dial to display showed 15%, look at the location referred to is the dial number, a similar measure later material that choose this stall. If the displayed value is greater than the actual water value, will dial clockwise, the numerical value to the actual water. The same note of this stall. After that you can not check.
4, replace the battery: When the zero adjustment knob can not be adjusted to within ± 00.5 or digital display erratic jump, replace a 9V (6F22) battery. The battery cover up a plug, replace a 9V battery.
