Volume, size and weight
Nominal volume	80~1000L，品達公司可承制非標試驗設備。
Performance
Test environmental conditions	An ambient temperature of + 5 ~ + 28 ℃, relative humidity ≤85%,under conditions of no sample within the test chamber;
Test Methods	GB/T 5170.2-2008 Temperature Test Equipment GB/T 5170.5-2008 Humidity Test Equipment
Temperature range	-70℃～+150℃
Control accuracy	Temperature:±0.2℃ （The difference between the controller setpoint and actual value of the controller）
Temperature fluctuation	≤0.5℃（Temperature fluctuation is half the difference between the center of the highest measured temperature and the minimum temperature.）
Temperature error	≤±1℃（The average temperature of the studio temperature controller displays the value to minus the average temperature measured of the center）
Temperature uniformity	≤2.0℃（Temperature uniformity is each difference in the measured maximum and minimum temperatures of the test of arithmetic mean.）
Warm-up time	3℃/min（Nonlinear load）
Cooling time	0.75~1.2℃/min（Nonlinear load）
4.11 Working noise	A Sound Level≤70dB(A) (At ambient temperature 25 ℃ and measured in the room of echo less interior noise; Using A-weighted, average of eight test points; Each test point level from the noise source 1 m, the height from the ground 1 meter.)
