BJPX-HTW300 (PC) | Constant Temperature and Humidity Weighing Box

Product Introduction

The constant temperature and humidity weighing box is mainly used for sample weighing in atmospheric PM2.5/PM10 monitoring, source apportionment, ultra-low emission monitoring and other projects. The entire weighing process strictly complies with the requirements of HJ 618-2011, HJ 656-2013 and HJ 836-2017 standards, and is the core equipment in the weighing process of atmospheric and pollution source sampling samples. It can also test the performance of materials in a given temperature and humidity environment, including heat resistance, cold resistance, dry resistance, moisture resistance, etc.

Technical indicators

1. The inner liner is made of stainless steel panel material; Multi layer adjustable shelves, anti slip and detachable partition design, convenient for loading; The exterior of the box is made of carbon steel sprayed with plastic;

2. The insulation layer adopts polyurethane insulation board, which has good insulation performance and reduces the influence of external environmental temperature;

3. Double layered door structure, with acrylic inner door as the sealing door and magnetic door seal design for the outer door, making it easy to observe the internal situation of the equipment;

4. ★ The side of the box is equipped with test holes, which can detect the temperature inside the studio according to actual needs;

5. It has a temperature limit alarm system function, which automatically interrupts when the temperature exceeds the limit to prevent damage to the instrument caused by excessive temperature;

6. Real time monitoring of temperature and humidity curves;

7. ★ One screen query of running history, standard USB data transfer, display screen switching between Chinese and English;

8. ★ A stable and adjustable temperature and humidity control system with a wider control range, eliminating the need for an additional constant temperature and humidity laboratory;

9. ★ The independent split support design of the refrigeration system reduces the impact of operating vibrations on the weighing balance;

10. Level 3 operation interface permissions (administrator, experimenter, operator) to prevent unrelated personnel from interrupting the experiment or causing equipment failure;

11. ★ Equipped with a standard interconnected PC interface for remote monitoring;

12. Equipped with waterproof sockets and detection ports, it can achieve power on operation of built-in devices, and connect internal and external data cables for communication;

13. ★ Has ISO9001 quality management certification and CE certification.
