DDB - 2 portable digital conductivity meter Brief introduction:
DDB - 2 type portable digital conductivity meter can be made to match the DJS - type 1 conductance electrode, the determination of various electrolyte solutions and conductivity of pure water, also can with the TYC - type 2 or imported soil salt sensor combination, determination of soil salt content and its dynamic change. Features:
1. The instrument has automatic temperature compensation function, when it is used with salt or conductance sensor electrode, can be easily directly measured conductance value shows at 25 ℃ or conductivity, overcome the use of general conductivity meter in the readout conductance value or conductivity at the same time, also should be determined by measuring point temperature, and then converted to 25 ℃ when the measured value, the procedure more troublesome shortcomings.
2. The instrument measuring conductance maximum value is higher, up to 1 x 105 orders of magnitude, so when faced with high salinity or high conductive value, with other conductivity meter measurement due to exceed the maximum limit, use the instrument can still be determined.
3. The instrument work stability, good reproducibility, and the operation is simple, easy reading, small volume, light weight, power consumption province, therefore particularly suitable for field under the condition of the application.
4. DDB - 3 portable digital conductivity temperature meter, in DDB - 2 type portable digital conductivity meter and on the basis of the function of measuring temperature. Technical indicators:
1. The conductance measurement range is 1 (including S - 100 ms (5 range).
(1) 10 ms - 100 ms
(2) 1-10 ms ms
(3), 100 (including S - 1 ms
(4) to 10 (including S - 100 (including S
(5) 1 (including 10 (including S - S (when the accuracy is not high, can read 0.1 (including S)
2. The conductance measurement precision: < plus or minus 1.5%
3. The temperature compensation error: "+ / - 2%
4. Stability: plus or minus 0.1% (full) plus or minus 1 word (per hour).
5. Weight: 380 g (including battery)
6. Size: 180 x 100 x 40 mm
