II. Petroleum Distillation Tester (Low-Temperature Double Tube) Performance Features

1. The instrument's measurement system features a front-mounted double-bend condenser tube made of 304 stainless steel for corrosion resistance. The quartz glass tube sleeve-type heater offers high thermal efficiency, oxidation resistance, oil splash protection, safety, and economy.

2. The instrument's heating chamber has an open glass window for easy observation. The distance between the heating furnace and the flask can be adjusted via a knob for convenient operation.

3. The cold bath temperature is controlled by an intelligent digital display temperature controller with PID auto-tuning function, ensuring precise temperature control and easy observation. The receiving chamber is equipped with refrigeration and constant temperature to ensure cooling for gasoline recovery.

4. The refrigeration system uses compressor refrigeration, featuring fast cooling speed and long service life.

5. The heating system is controlled by a solid-state voltage regulator for sensitive voltage adjustment, reliability, and durability. The furnace is connected in series with high-temperature quartz tubes, making heating element replacement convenient. The furnace lifting knob uses a reverse spiral clamping mechanism for sturdiness, durability, and easy disassembly.

6. The instrument's bath tank is made of stainless steel, offering corrosion resistance and good sealing. The cooling medium is pre-filled before delivery, so users do not need to add it.

7. The instrument is equipped with a cooling system; when the fan is turned on, it cools the furnace, improving experimental efficiency.

8. The overall structure is rational, with an aesthetically pleasing appearance and convenient operation.
