Rated 2 out of 5 by from Temperature logger needs working app for Win10 The HH303 temperature data logger is an acceptable device, but it lacks a functional computer application that works on WIN10. I had to write my own using VB. I then added communication capability for HH378. I don't know why OMEGA can't write one app to rule them all.

I am looking for a temperature indicator that gives an indication once the reading settles down (steady state). Imagine a body temperature thermometer that indicates once the temperature stops rising. Can you suggest a model

Asked by: SanjayV
The Thermometers Omega sells will sample and display at a preset rate and do so continuously. On most meters there is a max., min. and avg. function that may provide a good record of how the temperature acted over a measurement period which may be helpful.
