在本文中，我们评估市售的生命时间为基础的光学探头的性能，并与其他方法获得的数据进行比较。 针对不同水质，包括浅海水、污水、深海水等，一共做了11个不同的实验，包括对比目标实验室值、和现场研究。得出的结论是，这种方法，由于精度高（± 2um），长期稳定的（超过2个月）;不受污染物的影响，没有压力的滞后和交叉灵敏度限制，比其他方法更适合长期稳定监测溶解氧。 In this paper we evaluate the performance of a commercially available life-time based optode and compare it with data obtained with other methods. A set of 11 different tests including targeted laboratory evaluations and field studies were performed covering a wide range of situations from shallow coastal waters and waste water treatment plants to abyssal depths. The principal conclusion reached is that this method, due to high accuracy (±2 μM); long-term stability (more than 20 months); lower fouling sensitivity; no pressure hysteresis and limited cross sensitivity, is overall more suitable for oxygen monitoring than other methods.
