1. Air conditioning

1.1 air conditioning mode: forced ventilation internal circulation balanced temperature regulation (BTC);

1.2 air circulation device: built-in air conditioning device, circulating air duct, long axial flow fan;

1.3 nitrogen flow meter can be installed to adjust the air intake and air discharge, and the drying effect is better

1.4 heating method: superior nickel-chromium alloy electric heater.

2. Compartment structure

2.1 box structure: the box adopts assembled structure;

2.2 shell material: electrostatic spraying of fine cold-rolled steel plate;

2.3 inner wall material: stainless steel plate;

2.4 insulation materials: ultra-fine glass fiber;

2.5 shelf: 2 layers

2.6 gate seal: adopt environment-friendly silicone rubber strip.

3. Measurement and control system

3.1 temperature measurement: Pt100 platinum resistance;

3.2 control device: Japanese SHIMAX digital temperature controller:

· temperature control mode: no overshoot expert PID algorithm temperature control

· how to set the temperature: push the ▲ - fused button to set the number

· temperature display: LED digital display for setting temperature and measuring temperature

· the product has self-setting function to ensure that the temperature at each set point is constant

· the product has the function of linear compensation to avoid the invariable display error

3.3 the product is equipped with over-temperature protection device, which is used to set the upper limit of working temperature alarm to prevent damage to the sample and test box due to failure;

3.4 operation mode: run at a constant speed while the program runs.
