Selection of temperature and humidity meters

There are many kinds of temperature and humidity instruments, and the actual application environment and requirements of the user should be considered when selecting, such as range, output and display, installation method, sampling method, gas type, material and structure, control and monitoring requirements, environmental hazards, etc. In addition, we should also pay attention to factors such as cost performance and maintenance workload: The temperature and humidity instrument is rugged and durable: The sensor and housing of the hygrometer must be tested for a variety of temperature and humidity instruments. The actual application environment and requirements of the user should be considered when selecting. Such as range, output and display, installation method, sampling method, gas type, material and structure, control and monitoring requirements, environmental hazards, etc. In addition, we should also pay attention to factors such as cost performance and maintenance workload: The temperature and humidity instrument is rugged and durable: The sensor and housing of the hygrometer should be considered whether it can withstand condensation, dryness, extreme temperature, dust, chemical, or other pollution. Quality reliability and average life of temperature and humidity instruments: When the quality is not good, you can start from the overall impression to examine the quality appraisal and factory standards, and examine the manufacturer’s history, reputation, market share and application. Famous-brand products are better than ordinary products. The products of professional manufacturers are better than those of one side, and consulting other users is also a good way. The adaptability of temperature and humidity instrument: when the use situation is not a single type, the adaptability of the instrument should be considered. Replaceability: It is generally hoped that the hygrometer can be used interchangeably or other probes to match your host. Maintenance: Investigate the time requirements for regular cleaning, renewal, and replacement of the hygrometer. Spare parts of temperature and humidity instruments: Spare parts are indispensable for most users. Check whether the supplier can conveniently provide the required spare parts on time. Temperature and humidity instrument cost performance: When choosing a temperature and humidity instrument, you can't just consider the low price, you should choose a comprehensive price and performance. This includes price, life, maintenance, and calibration costs. Verification: The method of verification and whether it is easy to make should be considered, even if you do not need high-precision results. For instruments that are convenient for on-site and in-situ calibration, you will save your workload.
