SENSEZ Level Memory 4CH Water Level Observation Systems
Products Made in Japan
Manufacturer :SENSEZ
Model :Level Memory 4CH
Water level observation system using 4-channel data logger capable of long-term observation
Features
- Immersion-type
- 4-channel type
- System consisting of an immersion-type water level meter and a 4-channel data logger. Text data is transferred to a PC via USB memory.
- Atmospheric correction is not required because atmospheric pressure is released via the vent filter of the waterproof casing housing the water level meter cable and logger.
- A desired model can be selected from a range of 2 m to 50 m for highly accuracy measurement.
- The measurement data is displayed in meters with a direct reading method. It is possible to set the display and measurement of the water level from the datum line.
- Exchangeable AA batteries enable long-term measurement.
- The backup function is supported.
