Comes packed in a cardboard box fitted in cutout foam for very secure transport because of sensitivity of the sensor. Screws are included for mounting the module driver but no nut and secure washed for BNC connector as it was shown in the description. The sensor comes with cleaning fluid. The module has slightly different "temperature compensation" element than it's shown in description. The rest of the components look identical. Everything looks well packaged. Will be testing it when I get my buffer PH packets.
Fast postage and works well
