How to choose the correct temperature and humidity measuring instrument
Due to the different temperature and humidity measurement principles, the temperature and humidity instruments are various, and the user's actual application environment and requirements should be considered when selecting, such as range, output and display, installation method, sampling method, gas type, material and structure, and control. Monitoring requirements, environmental hazards, etc. In addition, we must pay attention to factors such as cost performance and maintenance workload:
1. Cost-effective: When choosing a temperature and humidity meter, you can't just consider the price is low, you should choose the comprehensive price and performance. This includes price, life, maintenance, and verification costs.
2. Verification: The method of verification and whether it is easy to consider, even if you do not need high precision results. Save time on your instrument for on-site and in-situ calibration.
3. Rugged: The sensor and housing of the hygrometer should be considered for compliance with condensation, drying, extreme temperatures, dust, chemicals, or other contamination.
4. Quality reliability, average life: When the quality is not good, you can examine the quality and factory standards from the overall impression, and examine the history, reputation, market share and application of the manufacturer. The brand-name products are better than the general products. Manufacturers' products are better than one manufacturer, and consulting other users is also a good method.
5. Adaptability: When the use situation is not a single type, the adaptability of the instrument should be considered.
6. Replaceability: It is generally desirable to use a hygrometer interchangeably or with other probes to match your host.
7. Maintenance: Inspect the time requirements for periodic cleaning, renewal, and replacement of the hygrometer.
8. Spareness: Spare parts are indispensable for most users. Check if the supplier can provide the necessary spare parts on time.
9. After-sales service: Is there a guarantee, repair and service agreement?
Choosing the right temperature and humidity measuring instrument will provide you with work efficiency, reduce the workload, and bring benefits to you and your production.
