[Shop-talk] Measuring ozone

[alfuller194 at gmail.com]

Jeff has a pretty good point – if you ‘assume’ the instrument is accurate at birth and the readings are consistent, you might just be OK. 

 

An additional thought: given the relatively low cost to make and the relatively high level of importance to you, you might want to make two [or more…] from the get-go. Then, you would have both a spare AND something to compare!

All the best,

It may not be as important to be accurate as it is to be repeatable.  If the machine is working and you get a reading, then as long as you get the same reading, you could assume the machine is working at the same level.

Al,

 

That’s what I planned to do but it will need calibration or at least verification. I don’t have a good handle as to how accurate the sensors are to the published specs. 

I suppose I could purchase a second sensor from a different manufacturer & compare the readings. If they come close to matching it should be close enough to being “Calibrated “.

 

Peace,

Pat

Pat, have you considered making one? A raspberry pi or Arduino base with an inexpensive sending might do the trick.

I need an inexpensive way to measure ozone concentration from time to time. 

I have an ozone generator that I’d like to use to deodorize a vacation rental after guests check out who have done rather odorous cooking, as well as attempting some level of sterilization. 

I can put together an inexpensive meter using available components but I have no way to calibrate it. None of the local environmental companies either don’t mess with ozone, they can’t be bothered or charge an arm & a leg. 

Thanks in advance. 

Peace,
Pat
