We are a group of engineers and tech entrepreneurs based in Houston, TX.
We create devices and software that meets the demand of the eco-conscious community for reliable data sources for informed purchasing decision making.

We assessed various risk sources and chose the most dangerous ones that could be detected by an inexpensive portable device during the shopping process.

Dual Electrical Method™ corrects the results of the original electrical method for the influence of natural acidity on the conductivity by measuring the electromotive force generated between two electrodes made of different metals being put into a testing sample.
Whereas the original testing method was prone to false positives due to variation of natural acidity of samples, the Dual Electric Method provided highly reliable results.

We also added a solid-state gamma radiation sensor, low-frequency EMF sensor and TDS-meter functionality to our device (read on that functionality in our Blog and watch our Video Manual in Docs).

Colbo is designed in Texas and assembled in Canada.
