Rain Gauge Query

Postby Richard_Griffith » 2015 Jul 17, 07:58

Does anyone happen to know if the CoCoRaHS Rain Gauge - http://www.weatheryourway.com/cocorahs/store.html is the same gauge as the one offered by MetCheck - http://www.metcheck.co.uk/acatalog/CM1016.html. It would appear that buying one direct from the US is cheaper than from here in the UK?

I belive it is. The dimensions are the same as the US version.

I have used on for many years and found no fault with it. I still have mine alongside my 5" gauge.

Stephen Burt has done a full test and review on his web pages if you want to compare the trials he did with a CoCoRaHS gauge versus a standard 5" gauge.

I had the CM1016 for many years, its weathered but is still working fine.

I did find the funnel only sat on top of the cylinder and I had to make adjustments to keep it secure, but other than that a good cheap alternative.

Similar but not identical, Richard. And by the time you've paid carriage and import duty, it won't be cheaper purchasing from the US - and it would almost certainly come fitted with inch graduations too!

Just to add to Richard Hunt's comments about the funnel just sitting on the cylinder. I noticed that too, and I was a bit concerned that it might blow off in gusty winds. I solved it with a few bits of Blu Tak just to hold the funnel on firmly.

Well, after some searching, I managed to purchase my CoCoRaHS Rain Gauge from Prodata Weather Systems here in the UK. Excellent service, I ordered online on Monday morning and the gauge arrived very securely packaged Tuesday. Installed on a 4"x 4" post. Results so far are promising with last Fridays' rain. Standard 5^ Gauge = 20.4mm / CoCoRaHS Gauge = 20.6mm.

Regards
