Analog thermometers are junk, you need an indoor/outdoor probed thermometer.
Analog thermometers are effected by the temperature of the glass which can be and usually is different than the ambient air temperature.
Also without a probed thermometer you can't know the temperature of the belly heat.

Better description of your set up is needed before anyone can really help.
Temps you get now
Type of heat your using
Size of enclosure
etc.
Pictures are especially helpful
