What are the differences between the YB88 oxygen content sensor and the ZO series?
Thread Content
The oxygen level in the boilers at our plant has always been inaccurate; during this year’s maintenance, the transmitter showed an oxygen level of 37% – that’s completely absurd! It uses ZO series zirconia sensors; before the heating season this year, they were replaced with YB88 zirconia sensors. I asked the supplier today and was told that the price is 7500 per unit, with a discount of 1000 per unit. But this model is more expensive – the ZO series is available on Taobao for 3800 per unit, while the YB88 costs over 7000? The price of YB88 cannot be found online.
Do you have any information on zirconia sensors of the ZO series? Could you send me one? Thank you, email: 16579@163.com
