Review on 🌊 Waterproof Temperature Indicator - Extech TM20 Review & Specifications by Carlos Barete

I review problem HVAC systems. I have used a Cooper Industries digital thermometer for many years. Still there. This type is good because it refreshes quickly and with metered fluid it's easy to tell when it's reached equilibrium. The folding function is convenient because the device turns off when you fold the probe. Save batteries! When you insert this stocking into a flexible channel or a flexible connector into a rigid channel, the support will unfold halfway, allowing you to hang the device so you don't have to hold it the whole time. Some reviewers complained that it didn't balance quickly enough. Well, to get that response time you need to have virtually no ground in the probe, which means you're stuck at the end of the thermocouple wire. Ideal for measuring free air or water pots. However, if you need to put the probe in a flexible duct or duct fitting, or in a pipe with a Pete connector, you need a solid probe. This evens out quickly, so I find these complaints unfounded. I don't give 5 casually. This is a good product.
