AH4000 Series Hybrid Memory Recorder

AH4000 series is a hybrid recorder which employs bright and clear, easy to view LCD display.

Measuring value display is prepared as 1 point display, multi-points simultaneous display and digital display + bar graph display.

Various measuring and recording settings can be easily done by front key switch and confirmed by LCD digital display.

Universal Power Supply
Universal power supply with voltage range of 100 to 240 V AC (50/60Hz) is applied.

Linear temperature scale

Temperature scale of thermocouple and resistance thermometer input is a linear scale that is excellent in reading value.

Standard 6 Chart speeds

6 Chart speeds (5, 10, 20, 40, 80, 160mm/h) are swichable as standard.
5 chart speed and hour/minute change are prepared as option.
