DDB-12 digital conductivity meter Brief introduction
DDB-12 digital conductivity meter , the conversion value of the measured conductivity of the solution FJA-10 -type soil salinity sensor ( Warming type ) access into the corresponding linear voltage signal for measurement can also be based on the type of measurement configure different measurement probe. It is the observation and study of saline soil and water salinity dynamics important tool to study the occurrence of saline soil , ideal for observing the evolution and improvement of equipment utilization. At the same time , it can also be used as underground oil and gas pipeline corrosion monitoring and other pipelines . Therefore , it is in all sectors in the national economy can be widely used . Features
1, the instrument with automatic temperature compensation function, when used with salt conductivity electrode used in conjunction with a sensor or can be easily measured directly shows the conductance or conductivity at 25 ℃, to overcome the use of general conductivity meter readout conductance value or conductivity , while the measured point temperature measurement needs , and then converted into 25 ℃ is measured values , the procedure is relatively cumbersome shortcomings.
2 , the upper limit of the instrument measured conductance value is higher, up to 1 × 105 micro West middleweight , so when faced with high salt content or high conductivity values other than the maximum amount due to conductivity meter limit can not be determined with use, the The instrument can still be measured by .
3, this instrument is stable, reproducible, and simple to operate, easy to read , small size, light weight , low power consumption , it is particularly suitable for applications under field conditions . Technical Parameters

DDB-12 type digital conductivity meter converts the conductance value of the measured solution connected to the FJA-10 soil salt sensor (warm compensation type) into a corresponding linear voltage signal for measurement. It can also be based on the type of measurement. Configure different measuring probes. It is an important tool for observing and studying the dynamics of saline soil and water and salt. It is an ideal observation instrument for studying the occurrence, evolution and improvement of saline soil. At the same time, it can also be used as anti-corrosion monitoring for underground oil and gas pipelines and other pipelines. Therefore, it can be widely used in all sectors of the national economy.
