EXTECH Instruments HW30 HeatWatch Humidity and Temperature Stopwatch

Gracias a Uds pude recuperar la herramienta de trabajo. Es excelente producto y facil de usar además de ser preciso

Great product to be used for outdoor sports and making sure temps are safe for athletes.

When you go out walking or running.if you have to time you're food. It fits around your neck. It's just a very good product very light. You don't have to bring your phone.

I have some other Extech instruments so I tried this one. I needed a humidity indicator. This is a stopwatch, temp, humidity, and heat index indicator. It was a bit slow in getting to the ambient temperature when I opened the package. The humidity takes a while to stabilize also. This would not be a problem if it was exposed to the environment all the time. I am keeping it in a dry box for scuba diving. It will be necessary to get it out at least 15 minutes or so before I need it. I contacted Extech and they tell me it is not water resistant. I have not examined it closely but there may be an opening to expose the humidity sensor.

Have owned this a year. Bought it to use on daily runs around a lake and occasionally on a high school track. I use the lap timer, the stop watch function, and the temp and humidity mode. I like the mode that tells your fastest lap on a track. The humidity and temperature take some time to sync to the real world, and both are affected when I wear it around my neck due to body heat and sweating when running (as expected). I have found the time lag with humidity read outs true with two other devices that I have. Humidity is important since I run in the summer in Georgia and Key West and the humidity eventually jives with weather web sites. The unit looks good, is sturdy, and is fairly intuitive. I would buy it again.

I love this thing! It works great for what I wanted it for. I was curious just HOW hot it is in my route-sales truck. Two days ago I got a reading of 139F heat index. Now I know why I am sweating so bad. :D My co-workers all wanted to know where to get one! I sent them to amazon...The unit itself seems well-made. The buttons react smoothly and the rubber non-slip grips on it are a nice feature. I'd recommend this item to anyone needing to know the heat index in their environment.

Seems extremely slow and inaccurate, I used it at work (indoor food manufacturing) temps reach high levels 120° or more. This thing maxed out and showed dashes ---°. Even when used in a known cooler area it read high, stuck it in front of an A/C vent and read 83° even though it obviously was cooler. Maybe if it hung around your neck outdoors all day and you just glance at it every so often it might be good for something.

This things fantastic, I commission heavy equipment and taking temperature readings is part of my job. Its important to have an accurate record of ambient temp. Also doing time studies is a breeze now that I dont have to keep using my phone... which can be a hassle with gloves on.
