Just get dimming thermostats. You can use them with everything unlike pulse or on/off thermostats. microclimate B1 stats I always use.
As for thermometers any infrared thermometer is going to be great and will be very accurate so don't buy expensive ones. And thermometers for inside the tank any digital ones with a probe will be fine as long as when you get them you test them to see how accurate they read.
Pretty much all hygrometers are off its just luck if you get one thats bang on So do the salt test on any hygrometer you buy to see how accurate it is.
Good Luck
