Quick Heating questions

So i have my terrarium set up with two infrared lamps and a UTH, the UTH reads at about 90, with the temperture on the cool side at around 83-85, on the hot side i also have another thermonitor that reads the temperature just above the substrate at around 87, is this too hot? (is this not air temp)

Is the UTH on a thermostat? what exactly are you using to measure temperatures?

If the thermometer is above the substrate then how is it not the air temp?

Sorry, i know it is the air temperature i just wanted too know if that was too hot?

no, the hot side (air can be included in this (though it doesn't have to be) should be 88-92 degrees, and the cool side needs to be between 78-82 (all of the air in the cage can be this temperature as long as a UTH provides a 88-92 degree basking spot. (UTH's do not change the temperature of the air in a cage)

When you measure your UTH's temperature you are measuring this with either a temp gun or a probed thermometer on the floor of the cage directly over the UTH correct?

No part of the cage should ever be below 75 degrees or above 95 degrees.
