      • 高低溫試驗箱TEMPERATURE TEST

       

       

      Product Model

      high and low temperature testing chamber MAX-TL720-10

      • Sample restrictions

      The equipment is prohibited to test below:

      Flammable, explosive, volatile substance's sample testing or storage;

      Test samples or storage of corrosive substances;

      Testing or stockpiling of biological specimens;

      Strong electromagnetic radiation source sample's test or storage;

      Testing or storage of radioactive material sample;

      Test samples or store strong toxic substances;

      • Volume, size and weight
      • Nominal volume

      80~1000L，品達公司可承制非標(biāo)試驗設(shè)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.)

      4.11. Meet the test method
