Elitech Temperature Humidity Data Logger, Reusable Recorder with Built-in Buzzer, -40~85°C, 64000 Points, Auto PDF/CSV Reports, Win/Mac Software, Calibration Certificate for Audit Compliance RC-4HPro

I have been using this device continuously for a week now, and have to say I am extremely satisfied in its performance. I needed a data logger to monitor the temperature and humidity in my refrigerator, and given the cheap price and good reviews on their other products, I figured it was worth giving Elitech a go. The device itself is very easy to use. It has a single button, which you press to begin recording, and to cycle through the current, maximum and minimum temperature values on the LED display. It therefore lets me crudely monitor the conditions without having to upload all the data. The software is a little clunky, but lets you do all the essentials - configure the device, stop recording, upload the data from the device, and erase memory. I have found it more useful to use my own scripts to analyze the data, but the pre-packaged software does let the non-programmer visualize the temperature and humidity over time, and zoom in to get a closer look. The biggest issue I had with operating the device, was identifying which driver to install for my mac. The instructions were not immediately apparent, and it was only when attempting to install the python module that I came across the solution. I installed both the CP210x USB-UART bridge VCP driver and the CH340 Serial Driver, and it was only after installing the second that the software was able to recognize the device. I have not had any issues yet with operating it continuously at 0-10°C (and once briefly below freezing). Once I have satisfactorily monitored all the different regions of my fridge, I may be daring enough to throw the thing into the freezer and see how it fares. But I know that batteries and sub-zero temperatures are not good friends, so don't have high expectations.

This is one of the best instruments I have ever used. I have several Meters for multipurpose and this unit is the best in terms of efficiency, design, software. If you really need to monitor Temp and Hum and log the information there is no chance to go wrong with this unit.

You have to install proprietary (free) software in order to use this device. This is on contrast to some other USB-based devices that allow you to access the device as if it was a thumb drive and simply copying a data file. You also have to use the maker's software to change settings like how often the temperature/humidity sample is taken. The ability to control the device itself is limited pretty much to just staring and stopping the logging. Finally the data can only be saved as a PDF, a complex Excel spreadsheet, or an archive format that can only be read by the maker's app. If you have no issues with these requirements and limitations, the device itself is easy to use and works well. My first use case was to see how long it takes for a new air condition to cool down a bedroom to the desired temperature. For recording the temperature, either the internal sensor can be used or a plug-in sensor is supplied. Unfortunately the device will not record readings from both the internal and external temperature sensor. But then that would make this a 3 channel data recorder (internal temp, internal humidity, external temp) which I suppose is asking a bit much give the relatively low price. But it would have allowed doing things like comparing inside and outside temperatures for things like rooms and refrigerators. A tip on using the graph view on the application. There are very few timestamps displayed on the X-axis and you cannot change this (AFAICT). But if you place your mouse cursor on the curve itself, a pop-up will be displayed showing the recorded value and timestamp at that point in the curve. A better X-axis scale would still be nice to have.

Bien Completo !

Muy bueno excelente , para la temperatura y medicina de la humedad buen equipo

Really, really disappointed, only records 4-6 times and stops. Had similar problems with the Elitech GSP-6 and returned it and bought this one. Wouldn't recommend either one.

It works and I have been using it for a couple of months now. I would have given it 4 stars except for two issues concerning the software. First issue is that you have to provide personal information to download it from their website. Second issue is that there is a bug in the software in which the humidity data is not exported properly to an excel file. Instead of the date, the humidity column is filled with random dates! 11/5/2018: I ordered another one and was hoping to upgrade review, but they sent me an RC-4 in a mislabeled box instead of RC=4HC, so down to one star. 22/6/2018: Elitech was very responsive to the mislabeled item, so back to three stars.. Not to four stars yet, because, although they no longer require you to enter personal information to download the logging software, the latest version 3.30 still does not handle the humidity logging properly. In fact, in some ways, its worse: the earlier version 3.00 put garbage into the humidity column for exported excel files, but you could at least see the correct readings in the program. Version 3.30 displays incorrect humidity data everywhere.

PRACTICO EQUIPO

Excelente herramienta de trabajo. Mide con precisión

Good

El producto funciona bien y realiza lo que dice la descripción. Buen costo beneficio. Lo recomiendo.

Acabo de recibir mis instrumentos y Descargué e instalé el software versión 6.3.0; al conectar el instrumento no me aparecen todas las opciones de configuración que he visto con otros dispositivos Elitech, por ejemplo la opción de configurar la hora programada de inicio, la opción de generación el archivo PDF al conectar el instrumento ni la opción de configurar varias alarmas o inhabilitarlas; estas configuraciones las he podido realizar antes con otros instrumentos de la misma marca y modelo; la facilidad de configuración que había observado fue lo que me llevo a adquirir estos instrumentos; si hay algo extra que debo realizar o si estoy haciendo algo incorrecto, me pueden indicar, de otra forma tendré que devolver los 10 instrumentos que adquirí

I need service centre contact detail first time i took the report second time its not getting started i need guideline for this
