The ultimate in resolution and accuracy

With up to 24-bit resolution the ADC-20 and ADC-24 USB data loggers are 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

Both the ADC-20 and 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.

terminal board for the ADC-20 and ADC-24

With as many as 7 bipolar voltage ranges, the ADC-20 and 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-20 and 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-20 and 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.

PicoLog data acquisition software

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.

The answer to your data acquisition needs

The high-resolution ADC-20 and ADC-24 provide you with a multi-channel, precision data acquisition device. 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 answer to your data acquisition needs.

When you need the ultimate in high-resolution and accuracy, the versatile ADC-20 and ADC-24 provide you with a portable answer with the performance and flexibility you need.
