Xikar Deluxe Calibratable Digital Hygrometer Thermometer

Does the job well. Cannot quote the accuracy but from reviews this is one of the best at its price.

Xikar never fails!

The look and feel is of high quality. There is an obvious difference between this and the many other cheaper hygrometers on the market. That said, the price difference is like chalk and cheeseIt's akin to the difference between a genuine TAG watch and a fake. Once in the hand the real one is a lot heavier and the materials are distinctly high grade. Even the LCD seems higher contract and has a modern font.It has a max/mix memory function I like, and the back comes with a magnetic strip and counterpart which sticks to the surface of your choice.Overall a lovely bit of kit. Only drawback is that it needs to be calibrated. Some may see this as a good feature, and it would be if it was not so hit and miss. It comes with good instructions but regarding the calibration it is not very explicit. Says to calibrate you need a soda cap. I have used several 'soda caps' and they all give different results, none which I am happy or confidant about.In conclusion; high caliber bit of kit, but not confidant that the reading is spot-on accurate.

POOR PRODUCT MISADVERTISED - This item is advertised as Calibratable, but it isn’t ... that would imply you can adjust the sensor to adjust for any error in reading following use of a 75% humidity bag. Mine was 9% out and you can’t adjust it RUBBISH Furthermore in noted I see that they say it’s self calibrating.. that’s not possible as it wouldn’t know the error margin without a controlled humidity bag
