Matters needing attention when purchasing temperature and humidity measuring instruments
Due to the different principles of temperature and humidity measurement, there are a variety of temperature and humidity instruments. Therefore, the user's actual application environment and requirements must be considered when selecting, such as: range, output and display, gas type, material and structure, installation method, sampling method, control monitoring requirements, environmental hazards, etc. It should be noted that in addition, factors such as cost performance and maintenance workload must be paid special attention to:

性价比:在选用温湿度仪表的时侯,不要只考虑价格便宜,还应该综合价格和性能来做选择。 1. Cost-effective: When choosing temperature and humidity instruments, don't just consider the cheap price, you should also choose the price and performance. This includes price, life, maintenance, and verification costs.
校验:校验的方法要和是不是容易作之间要做实际的考虑,如果你不需要高精度的结果,那么对于在现场和原地校验方便的仪器会节省很多的工作量。 2. Calibration: There is a practical consideration between the calibration method and whether it is easy to do. If you don't need high-precision results, it will save a lot of work for instruments that are convenient to calibrate on site and in situ. .

坚固耐用:湿度计的传感器和外壳必须要考虑到是不是能经受冷凝,干燥、极限温度,灰尘,化学,或者其它污染。 3. Ruggedness: The sensor and housing of the hygrometer must take into account whether it can withstand condensation, dryness, extreme temperatures, dust, chemicals, or other pollution.

质量可靠性,平均寿命:在质量不好判断的时侯,可以先从总体印象出发,考察质量鉴定和出厂标准,比如考察生产厂家的历史、信誉、市场占有和应用情况,一般情况名牌产品比一般产品要好,专业厂家的产品比一般厂家的要好,同时咨询其它用户也是一个很好的方法。 4. Quality reliability, average life: When the quality is not good, you can start with the overall impression and examine the quality appraisal and factory standards, such as the history, reputation, market share and application of the manufacturer. The product is better than the general product, the product of the professional manufacturer is better than the general manufacturer, and it is also a good method to consult other users.

适应性:使用情况不是单一情况的时候,必须要考虑仪表的适应性。 5. Adaptability: When the use situation is not a single situation, the adaptability of the instrument must be considered.

更换性:一般都希望湿度计能够互换使用或者其它的探头来配合使用的主机。 6. Replaceability: It is generally hoped that the hygrometer can be used interchangeably or other sensors to cooperate with the host.

维护:要考察湿度计的定期清洗、更新、更换的时间要求。 7. Maintenance: To check the time requirements for periodic cleaning, updating and replacement of the hygrometer.

备用性:备品备件对于大多数的用户都是不可缺少的,要考察供应商是不是可以方便准时的提供所需的备品备件。 8. Spareness: Spare parts are indispensable for most users. It is necessary to check whether the supplier can conveniently provide the required spare parts on time.

售后服务:是不是有保证书,维修和服务协议。 9. After- sales service: Is there a warranty, repair and service agreement.

When you choose the right temperature and humidity measuring instrument, it will provide your work efficiency, reduce workload, and bring benefits to you and your production.
