Specifications
SDJ series programmable constant temperature /humidity test chamberProduct characteristic
Balanced temperature & humidity control system(BTHC),thod control SSR .The heating and moisture system content is equal to the heat and moisture loss, therefore, can stability use long-term , liquid crystal display digital temperature controllers and humidity controllers, with RS485 communication interface..RS485 communication interfacetest data storage more convenient..
Main performance(room temperature 20°C,no-load )
1. Temp.range :-10°C~150°C;
2. Temp fluctuation :<0.8°C;
3. Temp.gradient:<2°C
4. Temp departure : <±2.0°C;
5. Heating time:from 0°C up to 150°C About 40 Min (Nonlinear no-load );
6. Cooling time:+25°C drop to -0°C About 35 Min(Nonlinear no-load);
7. Humidity range :20%~98%R.H.(Ensure that dry air can reach to min humidity);
