DDB – 12A digital conductivity meter Brief introduction:
DDB - 12 digital conductivity meter, the FJA - 10 soil salt sensor (removing) access to the conductance of the test solution into the corresponding linear voltage signal, for measuring. Also can according to the different measuring probe of measurement type configuration. It is saline soil water and salt dynamic observation and study of the important tool, is the study of evolution and improved utilization of saline soil, the ideal observation instruments. At the same time, it also can be used as underground oil and gas pipelines and other pipeline corrosion monitoring. 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. Technical indicators:
Salinity measuring range: 0.01 ~ 0.3 mol/L, the minimum reading is 0.01 mol/L, form a complete set of measurement precision is better than 5%;
Conductivity measurement range: 0-20 mS, minimum resolution: 0.01 mS. 0-200 mu S, minimum resolution: 0.1 mu S
Voltage and conductance correlation (linearity) : 98% or higher
The power supply voltage: 1.5 V battery (5) 2 section;
Instrument appearance size: reading table: 135 * 65 * 24 mm; Weight: less than 0.16 kg;
Working conditions: the environment temperature for - 10 ~ 60 ℃; Relative humidity is less than 90%.
