The J-Kem Temperature Controller is a great addition to any lab especially for those of you worried about accurate temperatures in various parts of your experiment/system. We currently offer two models of J-Kem Temperature Controllers: model 250 and 210.
The 250 unit allows for a top and bottom mantle to be plugged in and controlled, allowing for even greater heating potential. The units regulate temperature by producing a temperature-dependent voltage, which is then read by the unit. The J-Kem Temperature Controller can then calcualte how much electricity the controller needs to output (in pulses or short bursts) to achieve the set temperature.
