Product Description

Just about every athlete encounters a stopwatch at some point, but knowing when the weather is becoming dangerous is more important than knowing your time in the 40-yard dash. This Heat Index Stopwatch measures not only times, but also measures the ambient temperature, humidity and heat index, with a user-settable alarm to warn when conditions are dangerous. Measures time in increments up to 1/100th of second and can time up to 10 hours. Water-resistant; includes 39in. neck strap and battery.

5.0 out of 5 stars Maybe more info than you want to know!, June 16, 2011
Amazon Verified Purchase(What's this?)
This review is from: Extech HW30 Combination Humidity, Heat Index, and Temperature Meter; Stopwatch, Time Clock, and Calendar (Tools & Home Improvement)
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.

4.0 out of 5 stars Great in general, temp/humidity sensor takes time to adjust, December 9, 2011
Amazon Verified Purchase(What's this?)
This review is from: Extech HW30 Combination Humidity, Heat Index, and Temperature Meter; Stopwatch, Time Clock, and Calendar (Tools & Home Improvement)
I bought this product for recording the weather conditions when I run. The unfortunate thing about this is that the sensors are internal and require almost 20-30 minutes to adjust from your house to new surroundings like the outside. But it is very useful and durable nontheless. I would have loved it more if it had another row of numbers like some other stopwatches. But it works pretty well for the temp/humidity readings if you let it adjust. The heat index seems very off. If it's 35 deg out with 60% humidity, is the heat index really 80-90 deg?

4.0 out of 5 stars Excellent, October 27, 2011
Amazon Verified Purchase(What's this?)
This review is from: Extech HW30 Combination Humidity, Heat Index, and Temperature Meter; Stopwatch, Time Clock, and Calendar (Tools & Home Improvement)
I bought this stop watch for work. We need something that times up to 15 minutes normally sometimes more. As well we needed something that read temp in C not F as well humidity. This does it all and it will change humidity fast and accurate. Only issue I had was a small scratch on the screen of the stop watch as well when I ordered it on a Wednesday and he didn't provide the shipping label till near the end of the day on Friday. I didn't recieve it till Thursday afternoon the next week. But other than that I'd give it a 4 out of 5. Works great so far!!
