The ISD4000 is a survey-grade depth and temperature sensor that integrates a temperature-compensated piezo-resistive pressure sensor and a high-accuracy and low-latency RTD (Resistance Temperature Detector) probe located close to the water. Depth data can be provided to ±0.01% or 0.005% full scale accuracy, with multiple options available for range and configurable output rates up to 100 Hz. Temperature data can be provided to 0.1 or 0.05 degrees C accuracy.
The unit can also be fitted with a MEMS-based AHRS (Attitude & Heading Reference System) with sensor fusion for highly stable heading, pitch and roll measurement. Heading data is highly resilient to temporary magnetic interference, thanks to a built-in soft and hard iron calibration feature.
