Data Recorders

It’s an analog world – strain, pressure, voltage, current — these are the measurements that your Graphtec instrument will faithfully capture for you. On paper or in memory, or both. Trust these Graphtec instruments for your most important measurements!

Data acquisition (DAQ) is the measurement, recording, analyzing, and presentation of real world phenomena. It includes electrical measurements such as voltage, current, power as well as measurements through sensors and transducers including temperature, pressure, flow, level, strain, acceleration, pH, humidity, and more.

 Selecting the ideal recorders/data loggers depends on your application. Typical factors include sample rates, channel scalability, signal conditioning, sensor types, analysis capability, mobility, and environmental conditions we at Keith Electronics help you with these.
