High Precision Temperature Humidity Test Chamber / Programmable Climatic Test Chamber


1. Criteria

 

Performance indicators meet the requirements of GB5170, 2, 3, 5, 6-95 “Basic parameters verification methods for environmental test equipment for electrical and electronic products low temperature, high temperature, constant humidity and alternating humidity and heat test equipment”.

 

Basic environmental test code for electrical and electronic products test A: low temperature test method GB 2423.1-89 (IEC68-2-1)

 

Basic environmental test code for electrical and electronic products test B: high temperature test method GB 2423.2-89 (IEC68-2-2)

 

Basic Environmental Test Rules for Electrical and Electronic Products Test Ca: Constant Humidity and Heat Test Method GB/T 2423.3-93 (IEC 68-2-3)

 

Basic Environmental Test Rules for Electrical and Electronic Products Test Da: Alternating Humidity-Heat Test Method GB/T423.4-93 (IEC68-2-30)

 

Control Methods and Characteristics

 

Balanced temperature control system (BTHC) controls SSR by P.I.D. so that the heating and humidification of the system is equal to the loss of humidity and heat, so it can be used stably for a long time.

 

2. Refrigeration system
 

2.1 Compressor: fully packed compressor imported from France

2.2 Refrigerant: environmental friendly refrigerant R404A

2.3 Condenser: fin type heat sink motor

2.4 Evaporator: fin type multi-stage automatic load capacity adjustment

2.5 Other accessories: desiccant, refrigerant flow window, repair valve

2.6 Expansion system: capacity controlled refrigeration system

 

3. Main technical parameters
 

 Temperature range  -40℃ ~ 150℃
 Temperature fluctuation  ±0.5℃
 Temperature deviation  ≤±2℃
 Heating time  about 4 degrees /min (no load non-linearity)
 Cooling time  about 1 degrees /min (no load non-linearity)
