Configuration instructions for environmental chambers

Environmental chambers have temperature control functions. In addition to temperature control, they are divided into two categories: without humidity and with humidity control. Let’s talk about temperature control first.

Taking the WGD series manufactured by Kenton as an example, the temperature adjustment method adopts a balanced type. And PID intelligent control, that is, the heating and cooling systems will be turned on at the same time regardless of heating or cooling, so that the temperature fluctuation is small, and the PID intelligent control can minimize the temperature rush.

The temperature range is divided into three types: A: -20~150℃, B: -40~150℃, C: -60~150℃, heating rate ≥2℃/min (no load), cooling rate ≥1℃/ min (no load). Nickel-chromium alloy electric heating tube, high-temperature bearing motor with centrifugal wind wheel, refrigeration system adopts single-stage refrigeration or binary cascade refrigeration, imported French Taikang compressor, with overheating, overload, overcurrent, and overpressure protection. Fin type stainless steel welded plate evaporator. The temperature control system has two options: LCD screen and touch screen, programmable segmented control, can be set and kept constant within the temperature range, with timing function, error operation warning and ultra-high and low temperature alarm, temperature difference alarm, etc. The temperature accuracy is ± 0.1℃.
The WGD-SJ series with humidity control function is also known as high and low temperature humidity and heat alternating test chamber. The humidity range is 20%-98%, and the humidity deviation is ±1% (at 10-80℃) and the remaining temperature range is ±3%. The temperature and humidity control system is programmed and adjusted, and is particularly suitable for extreme tests of low temperature and high humidity and high temperature and low humidity.
