h2s电化学探头的保存H2S电化学探头是一种用于检测硫化氢(H2S)气体浓度的传感器,广泛应用于环境监测、工业安全和生命科学等领域。
为了确保H2S电化学探头的长期稳定性和精确性,正确的保存方法是至关重要的。
首先,H2S电化学探头应该存放在干燥通风的地方,避免长时间暴露在高湿度和高温的环境中。
湿度过高可能导致探头的电极表面受潮,进而影响传感器的响应速度和准确性。
温度过高则可能导致传感器部件的老化和损坏。
因此,建议将H2S电化学探头储存在温度适宜且气候稳定的环境中。
为了保护H2S电化学探头的传感器部分和相关电路,可以选择将其放置在密封的塑料袋或密封容器中。
这样可以防止尘土、液体和其他污染物进入探头内部造成损坏。
同时,也要避免探头之间的接触和碰撞,以免产生微小的损伤。
另外,H2S电化学探头具有一定的使用寿命,通常需要定期更换。
在不使用探头时,建议将其连接线拔下,以免长时间电流通过传感器。
这样可以延长探头的使用寿命,并避免电极表面的氧化。
对于需要在现场常备备用探头的情况,可以考虑使用特殊的探头保护盒。
这种保护盒可以提供额外的保护层,保护探头免受机械冲击和外部环境的影响。
当需要更换探头时,只需打开保护盒,方便快捷。
此外,定期校准和维护也是保持H2S电化学探头性能稳定的重要步骤。
根据厂家提供的指导,校准仪器以确保其测量结果的准确性。
同时,根据使用情况和厂家建议的频率,进行探头的清洁和维护。
清洁探头的电极和表面可以去除表面污垢和氧化物的积累,恢复探头的敏感性。
在使用过程中,如果发现H2S电化学探头的响应速度明显降低、读数不稳定或超出预期范围,应该及时联系厂家或专业人员进行维修和更换。
注意及时更换探头,并遵循厂家提供的使用和维护指南,以确保H2S电化学探头的长期稳定性和准确性。
总结起来,保存H2S电化学探头的关键是保持干燥、稳定的环境,进行适当的保护和维护,定期校准和更换。
这样可以确保探头的性能稳定和准确,提高其在实际应用中的可靠性和可用性。

In this circuit12. Notice on handling12-1. Seasonal variation of sensitivityHighly hygroscopic electrolyte is normally employed for electrochemical sensor, and then the sensitivity varies according to change of temperature and humidity, i.e. sensitivity is little lower in low humidity than in high humidity. Since it is because of amount of electrolyte, this seasonal variation of sensitivity should be taken into account in case that precise measurement is necessary.However, this variation is reversible phenomenon.12-2. Design of gas alarm or gas densitometera.Calibration of gas alarm or gas densitometer is to be carried out in clean air after the outputwas stabilized.b.Gas sensitivity reduction ratio of 2% per month is to be taken into account at designing ofgas alarm as recommendation. In case that precise detection is required, periodicalcalibration.c.In case that water drop or oil is on the pre-filter, accurate measurement may not be availablebecause of low diffusion of detected gas to sensor. If such accident may be conceived,design of prevention from such one is to be considered.d.Warranty time is 2 years in case of being used in normal circumstance.12-3. Storage of sensorIt is recommended that electrochemical sensor should be stored in normal temperature and humidity, possibly 0-20 degree C, of clean air.Recommended storage time after delivery is less than 6 months. If the storage time is extended, the warranty term is to be shortened. It is because the lifetime of electrochemical sensor is not dependent on being electrified or not like semi-conductive type or catalytic type, and then this matter is to be correctly comprehensive in order to keep quality.12-4. General notice・ Use only within specified conditions.・ Sensor characteristics must be measured in clean air.・ Electrode pins must be correctly connected. Wrong connection does not allow correct functions.・ Do not apply voltage directly to electrode pins.・ Do not bend pins.・ Do not put excess vibration or shocks.・ If sensor housing is damaged or scratched, do not use.・ Do not blow organic solvents, paints, chemical agents, oils, or high concentration gases directly onto sensors.・ Do not solder pins of sensor directly. Use exclusive sockets.・ Do not disassemble or change any parts.深圳市深国安电子科技有限公司地址:广东省深圳市龙华新区牛栏前大厦C507 蒋小姐:134 2876 2631 电话:86 755-85258900网址:www.singoan.com www.singoan.com.cn www.shenguoan.com・ In case that sensor is stored by detachment from circuit board, it is recommended that working electrode pin should be short-circuited with reference electrode pin in order toshorten the initial stabilization time.・ If sensor is used under irregular atmosphere, contact us.深圳市深国安电子科技有限公司地址:广东省深圳市龙华新区牛栏前大厦C507 蒋小姐:134 2876 2631 电话:86 755-85258900网址:www.singoan.com www.singoan.com.cn www.shenguoan.com。
