The Precision Temperature Water Bath is custom built
to fit four 500ml square bottles (included with the kit) and a Paterson
Tank (not included with the kit). The tanks are guaranteed to hold the
temperature to within 0.1 degree Celsius. The units are built with smart
tech thermostats and variable voltage heaters so that there is no
oscillation around the target temperature. Home color developing will be
infinitely easier with these kits.
