Single phase + protective earth wire

Transport(the test chamber is integral, transported as a whole)


Maximum size (without packaging): W700 mm×D1200 mm×H1500 mm

Conditions of use

Installation site

The ground is flat, with flatness ≤ 5mm / 2m

Good ventilation

There is no strong vibration around the equipment

There is no strong electromagnetic field around the equipment

There are no flammable, explosive, corrosive substances and dust around the equipment

Proper space for use and maintenance shall be reserved around the equipment, and the opening and closing space of the box door shall be reserved at the opening door of the equipment, and there shall be no other objects in front of the box door of the equipment.

Environment condition

Temperature: 5℃~ 35℃, Relative humidity: ≤85%, Air pressure: 86kpa ~ 106kpa

Power supply
