P R E C I S I O N - T H E L C O since 1903 it's what you don't ordinarily see that makes the big difference in Precision-Thelco Ovens. Features like heater controls that hold temperatures accurately, all-welded steel construction, fully gasketed doors that close vapor tight, yet are safety latched to release dangerous internal pressures. The heater, protected from spilled liquids by its diffuser plate cover, is designed for extra quality at no extra cost. Made of long-life nickel-chromium wire, it extends over the entire oven base area to promote uniform heating. Precision-Thelco Ovens are another example of how good design has made possible manufacturing efficiencies that are passed on to you in remarkably low selling prices. There's a complete Thelco line including vacuum ovens, drying ovens and incubators. All are in stock, ready for shipment. Write today for a free copy of Catalog No. 331A which has all the details.
