281L Constant Temperature Cabinet （Zhiheng Series） HW-281

Temperature Control System

1. Microcomputer temperature controller with a blue digital display and high temperature control accuracy. Features high- and low-temperature alarms, temperature sensor failure alarms, power-on delay protection, and proportional start/stop functions to prevent accidents;

2. Precise temperature probes and multiple sensors automatically display the internal temperature of the chamber, allowing for easy monitoring of temperature changes at any time;

3. A high-airflow fan ensures more uniform temperature distribution and minimizes temperature deviation.

User-friendly design

1. The interior of the cabinet utilizes ultra-microporous foam technology, offering features such as light weight and excellent thermal insulation;

2. Features triple-pane high-strength insulated glass, providing excellent thermal insulation and high transparency, making it easy to view the items stored inside the cabinet at any time;

3. Equipped with a brand-name hermetically sealed compressor that operates smoothly, produces low noise, and has a long service life;

4. Ceramic PTC constant-temperature heater with low power consumption and a long service life;

5. The cabinet is constructed of high-quality steel plate, with a 304 stainless steel inner liner and adjustable shelves for convenient storage of various items.

6. The cooling and heating systems are optimally matched and utilize forced air circulation to ensure uniform temperature distribution throughout the cabinet with no dead zones. Cooling and heating occur rapidly, allowing the set temperature to be reached in a short period of time.
