KH300B BLUE PAPERLESS RECORDER

KH300B blue LCD display paperless recorder has multi-channel input function, maximal quantity of input are 16 channels. It has full isolated omnipotence function on input type which suitable to various tran***ission signal including thermocouple, thermal resistance, standard voltage, standard current and pulse frequency. Output adopts the most advanced modularization structure. It can offer alarm, feed, transform, print and communication with module installation.

　　KH300B has 4 basic display modes: high precision bar chart display, real time curve display, history curve display, alarm record display. The data can be found according the defined time, it is convenient. Connected the printer to KH300B, the real time data on defined time, history data and curve data can be printed out by printer. By use RS485, it can configure with various special software such as Kingview and MCGS. By USB interface, the data can be read and downloaded convenient.
