Use these heaters as a dry, constant temperature source for various lab and research applications. All models have independent indicator lights to show main power, heater action, and over temperature cut out. A heater that accepts two single width blocks will accept one double width block. Use three and four block models for high throughput applications such as chemical oxygen demand (COD).
