Directing against problems existing in measuring conductivity in the pure water system of power plant

a YHJ -fl type movable chemical instrument checking apparatus has been developed and manufactured by Xi'an Thermal Power Reseach Institute Co Ltd. Adopting said apparatus

the on - line conductivity meter in water - steam system of unit no. 1 in Huaneng Rizhao Power Plant has been checked

and comparison with desk type checking apparatus in our country being carried out. The YHJ -II type movable chemical instrument checking apparatus has neccessary functions for checking pure water conductivity meters

such as for checking performance of the hydrogen exchange column

checking conductivity meter for eliminating the capacitance affecting capability

and checking non - linear temperature compensation etc.. In the event of u-sing said checking apparatus

it is not neccessary to remove the on - line meters

operation of checking to be rapid and convenient.
