Elitech RC-51H USB Temperature Humidity Data Logger Recorder Tester, 32000 Recordings, PDF Report, Multiple Alarms, Calibration Certified

I've been using these for several months now and I have not had to change the battery once so simple to analyse the temperatures. I just plugged it in my computer and within a few minutes true graphs turn up. we use it to monitor a few fridges that we have and these have not let me down that's why I've bought several of them. Very good quality and very accurate because I often monitor along with the fridges internal system and they match very well excellent battery life and very good value for money.

Brilliant small data logger for RH and T. Good graphing programme and easy to download and export the data.

We use it to track our products through the supply chain to prevent temperature/humidity abuse spots. It's excellent and gives great data. It's easy to use and well worth the money

Recording parameters cannot be changed on Mac using Elitech Log software from app store. App crashes when applying settings, so can't change how often it logs data, defaults to every 15 mins. Still generates PDF which can be viewed, at least.

Great for temperature logging over a set time period Works for fridges and rooms

Bought instrument to measure humidity on production plant. Found it easy to use and download data.

The description states data can be downloaded in excel format. The point of which would be to be able to filter data. If someone can find a way to do this please let me know as I have 6 of these which are close to useless for monitoring internal environments.

I had them for my job and they recorded figure regularly and it made my site visit goes smooth also covers my back with solid figures.

そういう商品ではありますが設定した時間の間隔通りに温度湿度を自動で記録してくれるのは非常に便利です。データの出力は簡単で良いです。設定方法はWEB取説見ても分からない人は無理な気もします。あくまでも海外メーカーですので不安な人は少し高くても日本メーカー買う方が設定が分からないなど不満を言わずに使えると思います。

Usato in speleologia, ottimo strumento, rilevazioni abbastanza precise, software migliorabile ma nel complesso soddisfatto

EXCELLENT PRODUIT Je l'utilise au quotidien pour mes relévés pro sur terrain il faut télécharger le logiel pour interprétation je le calibre à 1 min d'intervalles faut compter env 3 min de stabilisation de sonde donc j'ai entre 480 et 520 relevés jours et avec le site NOAA on peut calculer la chaleur ressentie HI (Heat index) très parlant surprenant mm je recommande a 400 % pour faire un réel terrain des ouvrier c'est top j'ai pu grâce a cet outil faire des plan canicules franchement outil conseillé à toutes entreprise btp formidable et pour le prix franchement ça ne cloue pas un budget ....

Works as advertised. Appears rugged.

Works as expected, and very good Software can be downloaded. You can monitor temperature (most important) and humidity (perhaps not so important, but anyway...) at a certain place, wherever you put the RC-51H (in my case I wanted to check the temperature in living room and bed rooms over a period of time, a couple of days. In the software you get a very clear picture of how the temperature has varied in the different rooms during the monitoring period. And the software is running on a new modern computer, 64 bit computer. (As opposed to some older loggers on the market which only runs under 32 bit computers.) And it's cheap! And good quality!
