KR3S Series Graphic Recorder

KR3000 Series are network-compatible paperless recorders with high performance and high operating function employed high visibility 12.1” TFT color LCD display and touch panel operation system. High speed of sampling rate 100ms for 48 points and high accuracy of ±0.1% were realized, and measured data is stored into internal memory and maximum 2GB compact flash card (CF card). As it can be monitored by a web browser display on several computers on intranet or internet, FTP transfer of data file and E-mail notification are also available.

Adopting clear 10.4" TFT color LCD display
High visibility display with various display functions. Real time/historical trend screen, bar-graph screen and numeric display are selectable for various applications..

Large capacity of data memory and various recording method
Compact flash card (CF card) slot is equipped as standard external memory. Large capacity storage of maximum 2GB is available.
Various data storing methods are selectable such as schedule programming by time of day and time of date, recording start-up by external signal and event, and data logging of before and after trigger points for alarm.

Multi points stable recording with high speed/accuracy
High-speed recording of approximately 1sec. for every points and high accuracy of ±0.1% are realized. Stable measuring and recording are possible with high speed. Withstand voltage between input channels is as high as 1000V AC (Excluding resistance thermometer input).

Easy operating and programming without manual
With touch screen display, operation and settings can be performed easily by touching buttons on the display.

Direct writing on the screen
With attached touch pen, various comments can be written on the screen.

Extend inputs with CHINO controllers
KR3S can communicate with up to 16 CHINO controllers for parameter settings and read/record of measuring values through low-order communications (Option).

USB port provided in front
Readout of data and files are possible by connecting through an USB memory stick for PC

Support LAN network (Option)
Through Ethernet communications (Option), various functions such as remote monitoring by a browser, and FTP server, and Email notification etc. are supported.

Analyzing/data acquisition application software (Option)
It is easy to replay and edit the recorded data file with the software. Replay display has various mode of vertical/horizontal trend, circular trend and also has wave-analyzing and marking by using the cursor.

Custom graphic screen for per each applications (NEW)
By using optional custom graphic screen function, it can display the graphic screen which the user created by PC software KR Screen Designer (optional). Create letters, rectangle, oval, line, etc by drawing tool and allocate KR measuring data while making the background by JPEG or other images. By lower communication, controller SV, MV, PID can also be changed. Register up to 5 screens and its screens are switchable.
