buying herpstat nd

so i found a herpstat nd, good price, is it like ranco, can i plug several devices in it, also looking at spyder robetics, you can get night drops, then i got to thinking is a herpstat Nd, mean herpstat night drop, or can it be used for a thermostat as well, sorry dumb questions but they guy wants to meet tomor, and we communicating through emails, he hasn't emailed back these question and i figured the great pros, on this forum could hit me back faster. :D
thank ya

I have one and you can connect three different heating sources into as long as their combined wattage doesn't exceed the wattage rating on the Herpstat ND of 600 watts. Herpstats have a proportional setting on them which will power the heating source to the set temperature by increasing or decreasing the power. Ranco stats are on/off which will achieve your set temperature by turning off or powering 100%.

does my 3 heat source have to be same watt, like say all of them have to be 20 gallon UThs or can i have 2- 20 gallon UTHs and 1 ten gallon UTH, thank you again.

herpstats are made by spyder robotics

To achieve the same temperatures, all of your enclosures will have to be exactly the same. Same size UTH's, same size tanks/tubs. Otherwise, you will get different readings on every set up.

If you're looking for a thermostat that can handle multiple different setups, I suggest the Herpstat II or Pro. The II can handle 2 different setups but the Pro can handle 4.

all my heat mats, are cobra and same size, tubs, etc.. just wondering my limits, the guys asking 50 dollars for it, so im getting it no matter what, only problem i have is? is it normal themostat or just the night drop, since its called a herpstat ND, (ND)- just mean night drop

It's also a normal thermostat. The ND is just an add-on as far as I'm aware.

oh, i got paranoid and though i was just buying a night drop

Yep, that's it. Another advantage to the ND over the regular Herpstat is that the ND has a resettable fuse that won't have to be replaced if it is overloaded.

I have 2 of the ND's that I use on my racks. You'll be fine. It's a proportional thermostat. The ND just has the extra Night Drop feature which can be used to drop the temps (you choose how many degrees) at a specific time or shut the heat off altogether.

You can plug a power strip into it if you need to power more heat sources. Just make sure the total wattage doesn't exceed that of the thermostat.
