As you probably know the MetO source their thermometers from Zeal.
On Zeal's website I found this:

NEW - Ordinary and Maximum type meteorological thermometers can now be supplied in non-mercury. Contact us for details.

Now isn't that interesting?


I think if I remember what Tony E said that they handt found anything that could replicate the Mercury thermoms, he mentioned Zeal. Perhaps not up to scratch. But dont quote me on that as I cannot remember exactly what he said. I was more concerned at the instructions for swapping the battery over at the end of the month !

However, I have still sent the following to Met'O enq's and cc'ed in Tony and Mike Stewart:

Dear Met’O – I am one of your official climate Stns (DCNN 7158) and have now had all of my mercury thermom’s removed, but not replaced.

Without wishing to go into the why, I am more interested in the when – so imagine my surprise when browsing the www today I chanced upon the following on Zeal UK’s website, the link being:
http://www.zeal.co.uk/meteorological-thermometers.html

NEW - Ordinary and Maximum type meteorological thermometers can now be supplied in non-mercury. Contact us for details.

This to me begs the question, what is going on and why will the replacement Max’ thermom be the Vaisala and not the Zeal?

Look forward to your reply.

Reply back from the Met'O is:
Thank you for your email, and your continued dedication to supplying data for the nation’s Archive.

I can confirm that the thermometers currently being calibrated have originated from Zeal, and will be used to replace your wet bulb. We are awaiting arrival from calibration and will be sent into the network as soon as possible. We will be in touch again shortly.

A tendering process was also run for the dry and maximum thermometers, this involved evaluation of a number of criteria, which the Vaisala was ultimately the winner.

If you would like to discuss further please do feel free to give me a call.

My reply to Adam is:

Adam – thanks for the reply.
Whilst I'm aware that the Vaisala will perform the max and DB, from the photos that I have seen it looks as though there is very little room left for ordinary hanging thermom’s once the Vaisala has been mounted and it will be interesting to see how it works – and the reading of the WB will also prove interesting with the Vaisala in the way – see photo below.
Is there still a commitment from yourselves for WB readings?
Guess that just leaves the 30+100 earth thermoms.
However, interesting times and just looking forward to being back up and running with approved equipment.

At least they have replied.

I am guessing that behind the scenes many staff are equally frustrated as ourselves but of course must tow the party line

Of course I am more a Boris type myself and I suspect Darren is aswell so always pushing the boundaries whilst remaining just about in control.

Your right about the room, the new device is very big. It can shift to the left. I may try and loosen and re -position and see if a wetbulb will fit

Battery failure this morning meant I had no max temp at 10am

Battery replaced and fortunately recorded data saved

I don't think they like me now.

Adam never replied to the above
When I rec'd my monthly owl returns I filled in the missing blanks for the x2 Mins and rain and again asked about Wow going forward - normally Mike Stewart replies, but it obviously got passed to Tony who replied.

I still do not know what 'they' want me to do with wow - albeit my e-mail to owl did say that when they get their arse in to gear and get me some new thermos that I would get my own arse in to gear and start submitting wow data.

However, my own records trundle on unbroken.
