Prologger - Model 7001D -Data Loggers
The Prologger 7001D-1 sets new standards in accuracy and input range. It is packaged in the robust enclosure so familiar to Starlog users with twice the accuracy, eight times the resolution, and sixteen times the dynamic range of its predecessor. All Prologger analogue and digital inputs are processed with 16 bit resolution.
The sixteen inputs now support the following ranges:
- ±5.000V (155uV/bit resolution)
- ±500mV (15.5uV/bit resolution)
- ±50mV (1.55uV/bit resolution)
- ±5mV (155nV/bit resolution)
The superior accuracy of the design means that input voltages will be converted to better than 0.05% of full scale over the full operating temperature range, and 0.1% in the 5mV range.
The Prologger’s increased memory capacity means you can acquire more data or increase the period between downloads. The unit also includes all the familiar Starlog features such as SDI-12 instrument support, modem command/dial-out support, universal battery pack, continuous power source, scheme control of power supplies, and field upgradable control firmware.
The Prologger can also be used with the Neon Internet logging system allowing users to view up to th eminute data directly on their PC, Laptop, Tablet or Smart Phone.
