main feature:

Bench temperature test chamber structural features:

1. The box is machined by CNC machine tools. The model is elegant, novel, and has no counteraction. It is easy to operate.

2. The box body gallbladder is made of imported high-grade stainless steel (SUS304) mirror plate or 304B argon arc welding. The outer shell of the box is sprayed with A3 steel plate.

3. The desktop thermostatic chamber uses a microcomputer temperature and humidity controller to control temperature and humidity accurately and reliably. (Japan OYO meter)

4. With a large observation window attached to the light to keep the inside of the box bright, and the use of double glass, at any time clear observation of the situation inside the box.

5. Unique independent temperature limit alarm system, automatically exceeds the limit temperature is interrupted, to ensure the safe operation of the experiment does not happen unexpectedly.

6. Optional recorder, the printer can print record setting parameters and scan out the temperature and humidity curve, 4 ~ 20mA standard signal.

7. The left side of the box is equipped with a test hole with a diameter of 50mm.

Bench temperature test chamber operation control system:

1) Controller: Imported microcomputer temperature and humidity integrated controller

2) Accuracy Range: Set Accuracy: Temperature ± 0.1°C, Humidity ± 1% RH, Indication Accuracy: Temperature ± 0.1°C, Humidity ± 1% RH

3) Temperature and humidity sensor: Platinum resistance PT100Ω/mV

4) Heating System: Fully Independent System, Nichrome Electric Heater

5) Humidification System: Externally Isolated, All Stainless Steel Evaporator

6) Dehumidification system: Using evaporator coil dew point temperature laminar flow contact dehumidification method water supply system: humidification water supply adopts automatic control, and can recover residual water. Water saving and consumption reduction

7) Refrigeration system: Fully-enclosed air-cooled single-unit compression refrigeration method, original French "Taikang", fully-enclosed air-cooled combined compression refrigeration method

8) Circulatory system: High-temperature and low-noise air conditioner type motor. Multi-blade centrifugal wind wheel

9) Safety protection: With leakage, short circuit, over temperature, water shortage, motor overheating, over current protection, controller power failure memory function
