Additional Feature

The HH1385 is a digital 4 input thermometer and data logger that works with any K, J, E, T, R, S, N type thermocouple temperature sensors (Please refer to the specifications table below). This unit offers higher accuracy and better uniformity across various thermocouple types. This device measures/stores over 16,800 temperature readings and allows up to 4 thermocouple connections that plug into a miniature female thermocouple receptacle at the base of the unit. The user can easily set up the initial data logging parameters including thermocouple type, logging Intervals, high/low alarm settings, and desired temperature units (°C,°F or °K). The user may also download the stored data by plugging the meter straight into a PC’s USB port and running the easy-to-use Windows software.

Rated 2 out of 5 by from Flawed, a little annoying, but usable We bought this because it records B-type TCs. The power adapter does not provide power, so it's batteries only. Power it off, power it back on, the date is reset, and it is tedious to re-enter it. It can be programmed with the date automatically if connected via cable to a PC running the software, but that's a pain, especially for a portable unit. Otherwise, it does its job. It does remember what recording interval and type of TCs, just not the date and time. Data downloads fine - rename the ending .CSV and it opens in Excel.

Rated 2 out of 5 by from meter fine, software aweful Meter has been adequate but the data-logging software has been useless. This meter has driver issues connecting to computers in the first place. I have only found it to work on 2 of the 5 computers that ti have installed it on. Not sure why. My IT department has not figured it out either. Software is not stable on computers that will connect. program crashes frequently especially every time you plug in or unplug a thermocouple wire. Have been trying to log temperature overnight and cannot get software to run long enough to do so.

Rated 5 out of 5 by from User Friendly After doing lots of research and reading the specification manual, I decided that this model would be the best fit for what we need. Everything came exactly how I expected. It is very user friendly but takes a little bit of time to read the user manual and figure out what all the buttons do.

Rated 4 out of 5 by from Does the job 2nd one I have purchased, gets a lot of demand for use on thermal qualification. Does what is needed for an ad-hoc "I need to log temperature on this point" and its known downsides aren't really a problem. Data is spit out in a CSV compatible format, just ignore the filename extension (or copy/paste from notepad++). Full disclosure on downsides: -PC interface works, but it a bit dated and data download is slow (might take a minute rather than being instant) -Chews through batteries on longer tests (eg. 24hr), power adapter is recommended -Does not remember the date after power-off. I treat it as a stopwatch from power-on -Not really useful to log once every 2 seconds due to refresh rates on multiple thermocouples not exceeding this. I usually just set it to once every 10 seconds anyways since parts I test change temperature sluggishly.

To confirm, will the display show the temperature measured by the thermocouples in real time? Or do I need to be connected to a PC as well?

Asked by: EngGradSM24
Thank you for your inquiry. This is a real-time thermocouple thermometer regardless if it connected to a PC or not.

Does this come with a Power adapter and USB cable?

Asked by: Guy1
Thank you for your inquiry Guy1. Unfortunately, the power adaptor and USB cable do not come with the HH1385 unit. You need to buy them separately. Please check the Accessories tab on the HH1385 product's page for these accessories.

1. Regarding your Item# HH1385 thermometer: will the software record (to a file) the temperature readings in real time? 2: Can I address it with my own software?

Asked by: Rav4801
Hi Rav4801, The meter can record direct to PC, real time. We do not offer software driver to make it compatible with alternate software. Best regards OMEGA

I want to write my own software to communicate with this device (in python). Is there a driver or reference for the communication protocol?

Asked by: StormWarden
Hi StormWarden, Please forward this question to TEMP@OMEGA.COM. Best regards, OMEGA
