    That's a big burger! It somehow looks more managable when it it broken down into individual paddies...

    Someone saw this picture and told be that it looked like it was froma place called denny's beer barrell. She said they have burgers like that and you get to eat free and get a t-shirt and your picture on the wall or something if you eat it all. But i'm not sure. I just think the picture is funny.

    No i have not. You're right in that the prh2 is off from the what a psycrometric chart shows RH% at the given db and wb. The SRH3 seem to be pretty dead nuts. That is at least reassuring, that the more expensive tool seems to be more accurate. The DB and WB were pretty much the same (1 degree diff between WB) but they showed two different relative humidities. I think these units read RH and DB and then calculate WB which to me doesn't make any sense when looking at these readings.

    Did you check the wet bulb temps with anything else like a regular old sling psychrometer or thermometer with a wet sock?
    Something seems up with the PRH2 if you put the numbers here.

    im a big fan of fieldpiece also.....
    im wondering if the induct psychrometer needs to have air going over it to read correctly? anyway im sure someone much smarter will be along soon to clear this up!

    Hey Fieldpiece guys!

    First off I love fieldpiece and use/buy their instruments whenever possible. Instruments are tough becasue we have to trust them. We base everything that we think we know off of them and so reliablitlty and confidence is crucial. So... I have a dealer who did an enviornmentaly sensitve MRI scanner room. The equipment is very humidity sensitive and the dealer is using a 7.5 ton reheat rtu for cooling and dehumidification. There is apparently some type of issue there with the humidity. So we could speculate all day what it is...i'm confident that i will solve it when i go out with the dealer next monday. In preparing for the field visit i was testing/calibrating sme of my equipment and ran into a discrepancy...Attachment 298241Attachment 298251

    As you may or may not be able to see from the pictures the pocket psychrometer and induct psychrometer are side by side. both units have new batteries and have been given about 7-10 minutes to acclimate. both units are reading 76.8 DB however the induct unit is reading 38.9%RH while the pocket psychrometer is reading 45% RH. The second pic is the WB temps: 60.9 on the in duct and 62 on the pocket - pretty close when it comes to WB, right on when it comes to DB. So why the difference in RH%? 6-7% is fairly significant...which should i trust? It's a little disconcerting, considering how much the in-duct psychrometer cost me...

    help advice would be greatly appreciated!
