It offers programmable memory for three countdowns, adjustable alarm volume with silent mode, and dual-color flashing LEDs for clear visual alerts. Designed for versatility, it includes magnetic backing, an easel stand, clip, and lanyard options, making it perfect for professional environments demanding reliable, precise timing. ## Description Traceable flashing LED alert big-digit alarm timer. Easy on the eyes: Massive, 1-inch-high display permits viewing from across the lab. Its microcomputer chip permits setting 3 countdown times into memory. Program the three most frequently used times and never set countdown times again. Use any countdown time from 99 minutes, 59 seconds to 1 second. When zero is reached, the timer starts counting up to show time elapsed since alarming. Unique visual indication when counting down, green light flashes every second once the countdown time reaches 10 seconds. Red light flashes when zero has been reached and the alarm is sounding. Adjustable alarm volume has three settings which allow setting the timer to a high decibel for noisy areas, low for quiet environments or off (muted) for silent only visual flashing LED operation. To assure accuracy an individually serial-numbered traceable certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (national institute of standards and technology). Magnetic back allows timer to be placed on any metal surface such as incubators or water baths. Also has a flip-open easel for standing on the lab bench, a spring fastener for clipping to a notebook/clipboard, and an opening for a lanyard. Accuracy is 0.01 percent. Supplied with two AAA Alkaline batteries. Review: Nice functional alarm - Not ideal for a louder industrial environment - This alarm is simple to use and has a nice display. We've had it a few months now and have used it consistently every day, and the batteries are still good. This alarm does not work well for our intended use, however. I didn't dock any stars for this because it has nothing to do with the performance or quality of the product. (I hate when people spend the time to write a review and they knock a rating because the item didn't fit their specific purpose). We have an industrial metal fabrication shop, so there is constant noise. We bought these to use with our powder paint ovens as they had no timer built in. We only have one time setting because the powder paint we use only has to bake for a specific time, so we have no need for the multiple time memory, but it's a good feature nonetheless. The alarm is not loud enough for our environment, unfortunately. The guys are using it in the paint room, which is a distance from the metal fab room where all the welding/grinding/pounding is happening, but the noise from there does interfere at times when it's particularly noisy. Also, if the guys are using the paint sprayer, it is a little hard to hear over the noise of that machine. The paint room is also quite large so if they are at the opposite end of where this timer is then they have a hard time hearing it. They could carry the timer around with them, but we have two ovens and they don't always get started at the same time so we like to keep the timer on the oven it's timing to avoid mixup. We also don't want them to get lost, obviously. Also, it only sounds the alarm for a minute. This might be good for many scenarios, but again, not for us. Because it's hard to hear, it would be nice if the alarm did sound for a few minutes so the guys would have a better chance of walking past it and hearing it. The main button does blink red when the alarm sounds, but it is not very bright and not very visible across a large room. When the alarm stops, it goes back to solid green so you can't visually see from a distance that it went off already unless you can see that the numbers are now counting up instead of down, which again, is difficult from across a large room. I don't think it's a bad alarm. I'm sure it's plenty loud for a household setting, or even a shop setting where there isn't a high level of noise. It just isn't loud enough for us, which is too bad. It's hard to buy something online like this because even though people say it's loud, like many of the comments on this product did, you don't have any way to really know. Review: Nice...with one mod, it would be a perfect timer. - Nice timer. One of the few that has optional silent operation. I had planned to use it to time video'd performances that can be no longer than 3 minutes. I read the specs that say the green light blinks once per second when it hits ten seconds, which would be great to warn the performer that time is close. ...Unfortunately.... it also blinks but at a slower rate during the entire timing event, making this timer useless for that application. However I did buy it for a kitchen timer also. On the loud setting, you can hear it from quite a distance. I like the magnets on the back. Because it had a tendency to slip off the counter, I put a couple of silicon microblobs on the back bottom only, so I could still use the magnets. Now it nicely stays put. The three time sets make it useful for timing lots of things including Pictionary. If the green light stayed off during countdown and you could set the time where it comes on once per second, it would be a perfect timer for events like I mentioned above (let's say you could set the light to trigger at 30, 20, or 10 seconds) to give you a warning that time is about to expire. ## Features - Flashing LED - Programmable memory - Adjustable alarm volume - Resolution is 1 second - Measures 2-1/4" width by 3-1/2" height by 5/8" depth ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 50 Reviews | ## Images ![Thomas 5013 Traceable Flash LED Alert Big-Digit Alarm Timer, 0.01 Percent Accuracy, 2-1/4" Width x 3-1/2" Height x 5/8" Depth - Image 1](https://m.media-amazon.com/images/I/51QjFf6rSCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice functional alarm - Not ideal for a louder industrial environment *by S***. on September 8, 2015* This alarm is simple to use and has a nice display.

I'm glad I have it *by 3***N on December 24, 2013* I am getting older and, with my age, I have become slightly forgetful. There have been times when I have left the water running in the kitchen sink. I have over-cooked a few meals, etc. But since I started using this timer, I have not had any senior moments in the kitchen. This timer is extremely easy to use. The numbers are large and easy to read. The alarm is fairly loud which is good for people who might have some loss of hearing. But to me, the sound is slightly irritating. When the alarm goes off, I turn it off as quickly as possible just so I don't have to hear it. Perhaps you can adjust the sound/volume. I guess I should go back and re-read the instructions! Otherwise, this is a great item to have. It has kept me from burning (and wasting) food. In that respect, this timer has more than paid for itself. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/10000175-thomas-5013-traceable-flash-led-alert-big-digit-alarm-timer](https://www.desertcart.vn/products/10000175-thomas-5013-traceable-flash-led-alert-big-digit-alarm-timer) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
