INTRODUCTION
FD-C chemical raw material moisture meter is the introduction of foreign advanced technology, first introduced in the country 's high-performance , digital moisture measuring instruments.
The instrument uses high-frequency theory , digital display, sensor and body as one, with a number of stalls used to measure various types of alkali reactive dyes , chemical mineral raw materials , organic and inorganic chemical raw materials , crude oil, heavy oil , dyes , resins , detergents , metal soaps, chemicals, solutions, additives , explosives , coal, plastic particles , fertilizer, medicine , etc. in powder, granular , liquid water .
The instrument measures the moisture wide range, high precision , clear display and rapid measurement, stable performance, reliable indicators , and small size , light weight , portable on-site rapid test , easy to use . Is detected by the chemical industry product moisture professional equipment .
Second, the main features
1 , the introduction of foreign advanced technology, imported chips, domestic assembly .
2 , the unique sensor design and production methods have the ability to penetrate beyond the ordinary .
3 , proprietary sensor technology a wide operating range , the measurement can be inserted quickly displayed.
4 , stable performance and excellent quality.
5 , portable instrument case as proprietary designs.
6 meter compact design, compact structure.
7 , the national patent number : 95205647.X
Third, the working environment
Temperature : -5 ℃ ~ +50 ℃ Humidity : ≤ 85% RH
Fourth, the working principle
The instrument introduction of foreign advanced technology uses high-frequency principle that there is a natural frequency within the instrument , different analytes water pass into the frequency sensor inside the machine is different, the difference between the two comparative frequency, frequency- to-current converter into digital display .
Fifth, technical performance
1 , measuring moisture range: 0 to 80%
2, the use of the environment : -5 ℃ ~ +50 ℃
3 , Accuracy: 0% to 1% Accuracy : ± 0.01%;
1% to 5% accuracy : ± 0.1%;
5% to 20 % accuracy : ± 0.5%;
20% to 40 % accuracy : ± 1%;
40% ~ 80% Accuracy : ± 2%
4 , Response time: 1 second
5 , the display : 3 ½ digit LCD LCD display
6 , probe length : 200mm
7, Power : 9V (6F22 type ) laminated battery a
8 , size : 160 × 60 × 27 (mm) 9, Weight: 200 g
Sixth, use
The moisture analyzer is a contactless measuring instruments , measuring premise is sensitive parts of the sensor ( in front of more than 10mm or less ) to full contact with the object , in general , sensitive parts of the sensor to be as in-depth as measured inside the object to reduce measurement errors.
Due to high frequency has a longer penetrating , so when measuring analytes , if the surrounding metal can cause inaccurate measurements , and called sensitive areas around the sensor should be inserted inside a metallic substance 20cm. Placing the measured object container diameter should be 50mm, height 50mm ( it should in no magnetic or metal ) above the cylinder , wherein the probe is inserted between the parts.
Seven, using the steps
1 , hand-held instruments, the sensor probe is screwed into the socket body .
2 , based on the object of moisture stalls of different options :
1 file ( Push up ) : 0 to 1% 2 files ( push down ) : 0 ~ 80%
When the water is greater than 1% should select two files.
3 different options for the continuous analyte dial position , due to the different kinds of chemical raw materials, the dielectric constant is different, and therefore should select dial position in comparison check.
4 Press the ON button, the display on the LCD screen (1 file : 0.00 ± 0.05,2 file : 00.0 ± 0.5). If not within this range , you should slowly adjust the zero knob (ADJ), so that the digital display to within 0 ± 00.5 . The probe is inserted into the measured object , to be stable figures , the figures show the value of the test object by water .
5 , numerical parity : When the measured value has an error , turn the dial. Such as : the measured actual moisture content of 5.2% , with a 7-speed test shows a value of 4.8 percent , the dial counter-clockwise , so that the display shows 5.2% , look at the dial position is referred to a few , similar measure later that stall when choosing this material . If the value is greater than the actual value of water , the dial clockwise , so that the actual value reaches the value of water . Also write down the stalls, after also without verification .
6 , 60 seconds after the instrument is switched off automatically , effectively save energy , protect the instrument longer use .
7 , replace the battery : When zeroing knob can not be adjusted to within 0 ± 00.5 or numbers displayed on the jump erratically , or when the upper left corner of the display shows LOBAT, please replace the section 9V (6F22) battery. After the battery cover up the horizontal push to replace a 9V battery. If the battery has power, open the battery cover , take out the battery with a small screwdriver to adjust the side of the small brass screw ( potentiometer ) , the case of a positive tone than zero , counter-clockwise adjustment ; contrary clockwise adjustment . |
