HK-1502 Mobile Inspection and Monitoring Device- E-commerce platform

Execution standards:

DL/T677-2018 "Code for Inspection of Online Chemical Instruments in Power Plants"

DL/T561-2013 "Guidelines for Chemical Supervision of Water and Steam in Thermal Power Plants"

At present, many thermal power plants in China, especially large capacity and high parameter units, have increasingly high requirements for water and steam quality. However, the current chemical supervision and control methods are online instrument analysis and offline manual analysis, and many power plants use offline inspection secondary instruments or standard solution static inspection of the whole machine to judge the accuracy of online chemical instruments. They lack connection and cannot be effectively combined to achieve measurement error analysis and judgment, and cannot truly reflect chemical supervision and control.

The HK-1502 mobile inspection and monitoring device is newly launched by Beijing Huake Instrument Technology Co., LtdA mobile online chemical instrument inspection and monitoring device that can simultaneously complete dissolved oxygenpH、 The dynamic monitoring of hydrogen/specific conductivity and ammonia content indicators is mainly used for the inspection of online chemical instruments in centralized heating and thermal power plants, as well as for the supervision and inspection of online chemical instruments by inspection agencies.

Application and Value
