What are the characteristics of high-quality drying ovens

A high-quality drying oven is definitely more expensive. So, from what aspects can we judge what drying oven is of high quality?
1. uniformity
Uniformity is good. Laboratories can try KENTON GX drying oven. They have uniformity. High-quality drying cabinets will be marked with uniformity parameters, while ordinary drying cabinets do not have this data.
2. Material of liner
The liner of drying oven in the market is nothing more than galvanized sheet, 201 stainless steel, 304 stainless steel, 316 stainless steel and other materials. These materials are actually different in composition. The chromium content of 304 is higher than that of 201, and the natural corrosion resistance is better. The quality and corrosion resistance of 316 are the best, and the price is the most expensive, followed by 304 and 201. Galvanized sheet refers to a steel plate with a layer of zinc on its surface, which has certain rust prevention and weak corrosion resistance, and will still rust after being used for a certain time. High-quality drying cabinets are made of 304 stainless steel liners.
3. Heating accessories
Electric heating tube is a tubular electric heating element, which is composed of resistance wire and crystalline magnesium oxide powder. Compared with ordinary heating wire, it has better overall performance, longer service life and easy maintenance.
4. Control instruments
High-quality drying oven requires precision and uniformity. Control instrument is the core component of the equipment, and the display is generally divided into LCD screen, digital type and pointer type. The control accuracy from high to low is LCD-digital-pointer.
