QLY-T high moisture moisture tester - tube measurement - Zhengzhou Zhonggu machinery equipment factory
Model: QLY-T
Product introduction
This instrument is a fast measuring instrument with high sensitivity and wide moisture measurement range for resistance type moisture and temperature. The maximum measured moisture can reach more than 40%. Our factory is the engineering and technical personnel to work together. To tackle technical problems, solve the measurement method can not measure the low water resistance and high moisture problems, according to the State Administration of quality supervision and Quarantine issued by capacitance method and resistance method of grain moisture tester of national standard (Draft) is a new type of measuring instrument design development and production.
Working principle：
(1) open the instrument sign and reveal the adjustment hole. (2) hold the key species, stop when the display shows the number of varieties to be adjusted, quickly press the key temperature display, 00 display (00 for standard position, if not the factory settings of the display 0 knob not in the middle position, does not affect the error adjustment, as long as the adjustment to error correction value can be 0. In order to increase the value of 0 * *, in order to reduce the numerical) clockwise to increase regulation, since the end of the initial rotation in the end, the display of 01 - 30; adjusted counterclockwise to reduce, display V 0.1 - 30 in the adjustment process to be fixed value can be adjusted, can according to the measured error. (3 J after adjusting, press the temperature key and display the display 000. When the instrument enters the test state, it can be tested, and the modified data can be reflected.
Basic indicators:
1, measuring varieties: wheat, corn, soybean, rapeseed, sorghum, japonica rice, Indica Rice
2, measurement of water range: Wheat 8 - 40% corn 8-43% soybean 6 - 35% rapeseed 3-34%
Sorghum 6-37% japonica 8 - 40% indica rice 7 - 37%
3. The main water range:
Wheat 10 - 18% corn 10 - 21% soybean 817% rapeseed 413% sorghum 10 - 20% japonica rice 10 - 2n% indica rice 1020%
4, temperature measurement: 20 C - 40 C.
5. Measurement accuracy:
A: the measurement error of the main water range is less than + / - 0.5%.
B: other water range measurement errors are less than + / 1%
C: the error of temperature measurement is less than + / 1 C.
6, instrument consumption of current:
A: shutdown state, the whole current is less than 0 2uA;
B: starting state, the current of the whole machine is less than 1mA
C: test state, the current of the whole machine is less than less than 9mA, which is related to the water content of the sample, and the duration of this current is 0.5 seconds per test.
Maintenance and maintenance:
L, often check the start contact of the sensor (the clamp sensor at the end of the handle, the cylinder sensor at the bottom of the barrel) to keep in good contact. If it cannot be started, it is generally that the starting contact of the sensor is in bad contact or broken line.
2. When the instrument is not used for a long time, the battery must be taken out in order to prevent the leakage of the battery. The circuit board that has been vacuoled by the battery will not be repaired.
3, the use of dust should try to avoid the dust from the ventilation hole into the instrument, and the internal ash is too much to reduce the insulation performance of the instrument. 4, the instrument is strictly calibrated before leaving the factory. Please do not disassemble it at will. In addition to the error adjusting knob in the circuit, the other elements are strictly prohibited.
5, the instruments and sensors should be kept clean and dry to avoid severe vibration. The sensors should strictly avoid knocking and touching to prevent deformation.
6, when the instrument is used for a long time, the front edge of the upper and lower teeth of the wheat sensor is blunt and blunt. When the measuring data is low, the tooth piece should be replaced. If there is not enough time to replace, the error adjustment knob can be adjusted to make a rough compensation.
7, customer service service: This product from the delivery date within one year + users if found quality problems because of their products in compliance with the provisions of the manual fault conditions, from the factory to be free maintenance, but because the battery leakage caused by circuit board scrap, the material cost of the bear, a years later when a fault occurs only if the collection of materials, use the factory product failure and cannot be ruled out. Please return the product factory, the factory will provide good customer service service for users
