24-Bits High-Resolution Data Logger

When you need the ultimate in precise and accurate data acquisition, the high-resolution ADC-20 data logger is your perfect solution.

The ultimate in resolution and accuracy
With up to 24-bit resolution the ADC-24 USB data logger is able to detect small signal changes. Features such as true differential inputs, galvanic isolation, and software selectable sampling rates all contribute to a superior noise free resolution, and ensure that your measurements are reliable and are accurate to within 0.1%.

Flexible, multi-channel data acquisition
The ADC-24 feature true differential inputs for excellent noise rejection. To give you a very flexible system each differential input can also be configured as 2 single-ended inputs. With up to 8 differential or 16 single-ended inputs on the ADC-24, this flexibility gives you complete control on what type of inputs you use. For example, you may configure the ADC-24 to use 4 differential and 8 single-ended inputs, or 2 differential and 12 single-ended inputs, and so on...the choice is yours.

With as many as 7 bipolar voltage ranges, the ADC-24 are also flexible enough to be used with a wide range of sensors and signal types. Whilst the optional terminal board provides screw terminals to allow you to quickly connect and disconnect different sensors.

Additionally, the ADC-24 has 4 configurable digital input/output channels that can be used to control alarms or other devices. You can configure these I/O channels in any combination. For example, 3 digital inputs could be used with 1 digital output.

The flexibility of these precision data loggers allows you to use the ADC-24 as an advanced multi-channel data acquisition system with a low cost per channel.

No need for power supplies or batteries
The high-resolution ADC-24 are powered directly by your PC — eliminating the need for batteries or a separate power supply, and making them ideal when you need a portable data logger.


Easy-to-use data acquisition software
All Pico data acquisition products come complete with PicoLog — this powerful, yet flexible, data acquisition software allows you to collect, manipulate, analyse, and display and export data. With PicoLog you can sample up to 1 million readings at selectable sampling rates; and using PicoLog, or our driver with your own software, you can connect up to 4 units to one PC.

Updates to PicoLog are available for free from our website, and you can download a demo of PicoLog to see just how versatile it is.

Your high-resolution data acquisition solution
The high-resolution ADC-24 provide you with a multi-channel, precision data acquisition solution. High resolution, true differential inputs, galvanic isolation, and selectable sampling rates combine to ensure your measurements are always precise and accurate. Configurable inputs, digital inputs and outputs, and programmable voltage ranges give you a truly flexible solution.

When you need the ultimate in high-resolution and accuracy, the versatile ADC-24 provide you with a portable solution with the performance and flexibility you need.
