Description
The MX2001-S Water Level Sensor is used with the HOBO Bluetooth Low Energy Water Level Data Logger (MX2001), the HOBO MicroRX Water Level Stations (RX2103 and RX2104), and the HOBO RX3000 Remote Monitoring Station for accurate water pressure, temperature, and water level measurements. These sensors are available in four depth ranges, as well as in stainless steel or titanium (recommended for use in saltwater).
Feature
- Non-vented design reduces maintenance
- Durable, ceramic sensor can withstand freezing
- 3-point NIST-traceable calibration certificate

* Water Level Accuracy: With accurate reference water level measurement, known water density, and a stable temperature environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected sensor Water Level Accuracy.
** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
*** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes. Measurement accuracy also depends on temperature response time.
