Help with Digital Thermometer / Hygrometer

[Sherlinwed]

Hey Guys,

I'm building a 5' x 3' x 2' 1/2" cage for my cham. I wanted to know if anyone would recommend the best Digital Thermometer / Hygrometer for this size cage?

I have a Zilla Digital Thermometer / Hygrometer with a probe at the moment. Is this capable of taking the temperature of a cage this size?

Any help will be greatly appreciated
