Data Logger

Deliver, Connect, Monitor:

After our qualified service team delivers and connects your equipment, our job isn't finished. CHI Companies will help monitor the project to ensure that the client's needs are filled. Our technicians can place moisture/temperature monitoring devices on the jobsite that calculate hourly or daily reports. We can send the project manager or superintendent these results upon request. These data-logger monitors are an excellent means to help manage your concrete pours, drywall, and painting projects.

Quality Control Checks:

In addition, CHI Companies technicians can perform a Quality Control Check on any project upon request. During a Quality Control Check, a technician will check the temperature, humidity level, natural gas meter size, and/or the LP tank size. Inside the building the technician will check each piece of equipment for proper voltage, safety clearances, thermostat settings, and carbon monoxide levels. The technician will also monitor the inside temperature and relative humidity.

When completed, a copy of the Quality Control Check is left with the superintendent and can be emailed to the project manager. To view a blank Quality Control Checklist Click Here.
