High Accuracy ±0.25%

By Large scale plate and sharp pointer location, it is easy to see the indication and high accuracy of ±0.25% (DC Voltage Input)

Universal Power Supply

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

Linearized temperature scale prepared

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

6 Chart speeds

6 Chart speeds (12.5, 25, 50, 75, 100, 150mm/h) are swichable as standard. 5 chart speed and hour/minute change are prepared as option.

Easy operation and robust structure

Operation switch and setting switch are separate arranged for easy operation and robust structure that adopted steel casing and die-cast door.
