Each tent has a
AC infinity exhaust fan control and a Inkbird ITC-608T to control humidifier in tent with there probes in tent. And have 4 ea. Govee H5100 sensors that only one is accurate out of the box. I use a 30 year old or older sling psychrometer to check calibrations points and set the needed off sets to get the china junk close to reading correctly. My gauge and sensor calibration shop I traded with for over 30 years closed there doors because Americans have become such half ass cheap sobs it wasn't worth it for them to stay open and put up with the china deep throaters. While I am retired I will go out and help a past good customer or friend with pump, boiler, chiller, cooling tower, heat exchangers or system issues. And I now have no idea where I'm going to go to keep my sensors and gauges calibrated.
