The Data Dolphin provides the accuracy of a laboratory instrument in the harsh conditions of the field environment. The ultra-high resolution 24 bit analog to digital section provides 8 single ended inputs or 4 differential bipolar inputs (or a combination of both) with resolution down to 90 nanovolts (.00000009 volts). This allows most sensors to be directly connected without any signal conditioning. It`s wide range of input voltages allows for you to attach a wide range of different input types. There are an additional four inputs that can be user selected as pulse, status, event start/stop or analog inputs.Data is stored in a non-volatile flash memory module that gives long term storage without the fear of losing your data because of dead batteries. Data is stored inside a database structure, which allows you to add or delete inputs `on the fly` without having to restart the datalogger. Even the sample rate can be changed without restarting.

SDI-12 sensors, data loggers, or sondes can also be connected to the DD-400 for a wide variety of monitoring capabilities.

The Data Dolphin provides the accuracy of a laboratory instrument in the harsh conditions of the field environment. It`s wide 0-5V range of input voltages allows for you to attach a wide range of different input types. The four externally accessed inputs can be used with 4-20mA sensors just by enabling a shunt inside the sensor connector. Sensor cables can also be identified for instant input configuration in the DD-600.Data is stored in a non-volatile flash memory module that gives long term storage without the fear of losing your data because of dead batteries. Data is stored inside a database structure, which allows you to add or delete inputs `on the fly` without having to restart the datalogger. Even the sample rate can be changed without restarting. Coming soon is the ability to store to the on board SD card.

The Data Dolphin Meter is a data logging flow meter head with a micro SD Card slot for retrieving your data. It is housed in a rugged cast aluminum enclosure and provides three threaded conduit holes and integrated pipe or wall mounting holes.The DD-METER can accept magnetic pickup turbine flow meters (AC signal), as well as magnetic flow meters (open collector signal) simply by changing an internal jumper position. The DD-METER can accept AC power and provide a 12V power source for powered meters, or can run for years off an internal lithium battery for use with magnetic pickup type flow meters.Analog and digital outputs are also available. The DD-METER can output a scaled pulse based on the K factor and units back to external equipment. When ordered with an additional communications daughter card, the DD-METER supports MODBUS communications to provide date, time, rate, and pulse to equipment such as a PLC.
