Elitech RC-5+ TE PDF USB-Temperaturdatenlogger mit externer Sonde -22℉~158℉

I use these to monitor HWS and CWS pipework on large commercial installations. Generally I am happy with the logger.

I would like to be able to manipulate the software side a little better to get the results I want but currently get what I need almost. I did not have any issues getting the software and others I feel maybe user error and not an issue with the software or loggers.

The excel output is locked so cannot be manipulated for bespoke chart creation.

The date and time is wrong and won't update so trying to get assistance but it takes ages.

The product design and set up capability is good and it is robust.

All in all I am very happy and have already purchased four more.

I have only had this for a few days and here are my thoughts

From the Web site descriptions
"Elitech RC-5+ TE PDF USB Temperature Data Logger w/ External Probe -40℃~85℃"
and note it says "Built-in USB port, no cable, no reader, even no software required to download data"

Well, I switched on the device and plugged it into a Windows computer USB port and nothing found on the external (D:) drive, but from the above I expected to find something to configure it with. After a lot of searching on the Web, I do have to download some software for settting it up. It is true once it's configured and recording, the reports are generated without any external software, EXCEPT they are generated by the configuration software previously downloaded.

The battery supplied with the device is a CR2032, which has a normal working temperature range of -20 to +80 deg. C, but the device is specified to work between -40 to +85 deg. C with the external probe, why couldn't it be at least be supplied with a BR2032 which has a better low temperature range of -30 to +85 deg. C. This is annoying and technical support can't tell me which battery they recommend for use at -40 deg .C as they expect only the probe to be exposed to these temperatures and the body near room temperature. Nowhere on the site is this mentioned, but assumed when they give the run times.

I only found out about the battery temperature range after I put it in my freezer (which ranges between -25 and -30 deg. C), I hope I have all my per minute reading when I take it out in a few day's time. I didn't want to just put the probe into the freezer as the door seal was compromised around the probe's cable.

Purchased to monitor a swimming pool water temperature in order to save expenditure on gas.

This device works great but it is let down by the instructions:

Stage 1: Connect it to a computer it says - I did that and literally nothing came up on the display. Eventually I worked out you need to download some software (it doesn't mention that in the instructions) from their website though my computer gave me loads of dire warnings thinking I was trying to download malware (can't Elitech get themselves a certificate?). Once I downloaded the s/w things started to happen...

The RC-5+TE would be even better if it logged the temperature at the probe and also the device temperature - at the moment it's either /or
The date in the Excel download file is not formatted as a date so it doesn't plot properly (if you want to do your own plot with sensible scaling) - you can fix this by converting text to columns in excel and using tab as a delimiter..it just takes time

Elitech are a great company to deal with and I've no hesitation in recommending them, I bought 2 RC-5 + TE temperature data loggers to monitor the performance of my central heating systems flow and return water temp in order optimize, they have worked flawlessly and the reports and data the device generates are superb.
