Hot Plates for water bath?

[markbarendt]

Mark,

Take a look at the horticultural type warming pads.... low enough wattage... (and an available thermostat you can purchase) that should allow for reasonable temperature maintenance.

The thermostats (which one should expect to be 'waterproof' in a horticultural environment) are further down that page...

Those look interesting, 200 watts seems a bit low for my application though.

Anybody tried using a hot plate as a heat source for keeping color chemicals at the right temperature?

Was recently given the heating mat from a water bed. It's about 40" long and 10" wide with a thermostat about 20" long. Have tried it to see if it works and it does. Only thing now is to tune the thermostat.

Well I picked up a 2-burner GE hot plate at WalMart for $33.

It is sweet!

Looks like it holds within a degree or so if I leave things alone. The thermostats adjust infinitely and cover all the temps I'll need.

Close enough for this boy.
