OK, so I am not the test editor here but I am old enough to remember those Gould Brush chart recorders with the little ink needles and long narrow rolls of paper. So it really took me back seeing ...

The Chromalox ECR1 electronic chart recorder allows precise trending and recording for any type of process. This paperless unit records and stores data from up to 18 process sensors, with multiple ...

With so many ways to capture images from paper, do we really need another one? Especially one that takes 15 minutes to capture a 128×128 pixel image? Probably not, but building a single-pixel RGB ...

ECR1 let users monitor up to 18 process sensors for recording, storing, and analyzing data. Multiple combinations of digital inputs and outputs trigger events or alarms. The recorder is configured ...

The CT89 series temperature chart recorder sports an advanced microcontroller design that enables it to accurately measure and record temperatures in air, gas, liquids, powders, solids, and ...

A simple, inexpensive method for building a temperature strip-chart recorder involves a parallel port that communicates with four TMP121 IC temperature sensors (Fig. 1). The sensors communicate via ...
