Sensors ZMOD4410 & 4510 - absolute minimum operating pressure

Question

Hello , 
 I would like to know what is the absolute minimum operating pressure for these 2 sensors? 
 My plan is to measure the concentration of gases under vacuum (~300 mBarA). Will these sensors withstand it? 
 Many thanks 
 Jeff

Hi Jeff, 
 Please let me provide you the feedback I received after checking your issue internally: 
 We have consulted with our R&D team regarding the air pressure range for the ZMOD sensor. Unfortunately, we do not have specific data for this parameter as our tests have always been conducted under ambient pressure conditions. However, we believe the sensor should function within an extended pressure range. It is important to note that performance may degrade at low pressures, and no gas sensor can operate in a vacuum. We anticipate that performance issues could arise before reaching vacuum conditions. 
 Hope it helps. 
 Best Regards,
