Kestrel 5400 Heat Stress WBGT Meter

The Kestrel 5400 Heat Stress WBGT Meter sets a new standard for accurately measuring heat stress conditions, offering portability, affordability, and unmatched capability. Whether you’re managing athletes, workers, or outdoor events in harsh Australian climates, the Kestrel 5400 delivers precise data to help prevent heat-related illnesses.

Key Features:

  • WBGT Measurement: The Kestrel 5400 provides real-time Wet Bulb Globe Temperature (WBGT) readings, a critical indicator of heat stress risk, used by professionals worldwide.
  • Thermal Work Limit (TWL): In addition to WBGT, it also calculates TWL, a globally recognised measure of human heat tolerance, factoring in personal clothing and environmental conditions.
  • Enhanced Screen: This device's high-contrast, sunlight-readable display and scratch-resistant window make it suitable for any environment.
  • Alert System: Flag warnings with a loud buzzer and LED beacon notify you when conditions reach critical levels, ensuring fast decision-making to protect people in high-risk situations.
  • Bluetooth LiNK: Seamless data transfer to smartphones, tablets, and computers. LiNK works with iOS and Android devices, enabling real-time data access and the ability to log, analyse, and share data remotely.

Practical Design for Tough Environments

Designed to withstand extreme conditions, the Kestrel 5400 is waterproof (IP-67 rating) and rugged, making it ideal for use in outdoor settings, industrial worksites, or sports events. The upgraded AA battery ensures long-lasting performance, with an average life of 400 hours.

Why Choose Wet Bulb Globe Temperature (WBGT) Over Heat Index?

The WBGT is the most accurate indicator for assessing heat stress risk because it considers temperature, humidity, wind speed, and radiant heat. The heat index only factors in temperature and moisture, which isn’t sufficient for assessing heat stress, especially in sunny or breezy environments like those commonly experienced in Australia.

Monitor Heat Stress Indoors & Outdoors

Whether in an outdoor sports event or an indoor industrial site, the Kestrel 5400 adapts easily. The 'indoor' WBGT mode eliminates the effect of direct sunlight, ensuring accurate measurements in factories, warehouses, and other indoor settings.

Precision with the Black Globe Sensor

The Kestrel 5400’s 25mm black globe sensor measures radiant heat from the sun and surrounding surfaces. This data, combined with air temperature and humidity, provides a detailed picture of thermal stress in the environment. Ideal for professionals in industries requiring heavy protective gear, this meter helps manage the risks of heat-related illnesses by allowing adjustments based on real-time data.

Easy to Use, Portable Weather Station

The optional rotating vane mount transforms the Kestrel 5400 into a full-featured portable weather station. Perfect for long-term monitoring or event planning, this feature allows for continuous data collection of wind and temperature conditions.

Additional Features:

  • Measures wind speed, pressure, humidity, heat stress index, and more.
  • Customisable data storage with 2,900 points for precise record-keeping.
  • Rugged and durable, meeting military standards (MIL-STD-810F).
  • Real-time data sharing via Kestrel LiNK for iOS/Android.
  • 5-year warranty for peace of mind.

Perfect for cracked heals ♥️
Color: Cheetah, Size: Regular, Color: Cheetah, Size: Regular
These are thick not cheaply made, has a nice texture inside the heal area which I love. I wear them at night after I apply Aquaphor to my heels & while sleeping they are very comfortable. I slipped these guys on & my heels are healing so much faster no more cracked heels for me. 😃 I highly recommend them.

These socks have saved my heels!
Color: Fuzzy Slate Gray, Size: Regular
I really love these socks and how they help my heels to feel. I tend to get large cracks on my heels, and wearing these while I sleep during the summer has saved me a lot of pain. One thing this has disappointed me a bit has been some unraveling of the threads around the top and bottom edges. Doesn't seem to matter how I trim them, the next morning when I wake up there is another hanging thread. Maybe it was just a glitch in the finishing of the batch of socks that I received. I would give them a second chance...this certainly isn't a deal breaker.

They work!
Color: Fuzzy Blue, Size: Regular
The ZenToes Moisturizing Fuzzy Sleep Socks have been a wonderful addition to my nightly self-care routine. Infused with Vitamin E, olive oil, and jojoba seed oil, these socks are designed to soften and hydrate dry, cracked heels, offering both comfort and skincare benefits. The regular size in blue fits perfectly and adds a soothing touch to my bedtime. One of the features I appreciate most is the intense moisturization these socks provide. The infusion of Vitamin E, olive oil, and jojoba seed oil delivers deep hydration to my feet, effectively softening and healing dry, cracked heels. After just a few nights of wearing these socks, I noticed a significant improvement in the texture and smoothness of my skin. My feet feel much softer and more comfortable, which is a relief after long days on my feet. The fuzzy, cozy design of the socks is another standout feature. They are incredibly soft and comfortable, providing a warm and snug fit that’s perfect for sleep. The plush material feels luxurious against the skin, making it a pleasure to wear them overnight. This added comfort enhances the overall experience, making it easier to stick to a nightly moisturizing routine. The design is practical and thoughtful. The socks fit snugly without being too tight, ensuring they stay in place throughout the night. The regular size is perfect for my feet, and they accommodate a range of foot sizes comfortably. The blue color adds a touch of style and fun, making the socks both functional and visually appealing. The socks are easy to care for, which is a significant advantage. They can be hand-washed or machine-washed on a gentle cycle, and they retain their softness and moisturizing properties even after multiple washes. This durability ensures that the socks continue to provide effective hydration and comfort over time, making them a worthwhile investment for foot care. The moisturizing effect lasts long after I take the socks off in the morning. My feet remain hydrated and smooth throughout the day, reducing the need for additional foot creams or lotions. This lasting effect is a testament to the quality and effectiveness of the ingredients used in the socks. Overall, the ZenToes Moisturizing Fuzzy Sleep Socks have exceeded my expectations. Their combination of deep moisturization, cozy design, practical fit, and easy care makes them an essential addition to any skincare routine. The socks have significantly improved the condition of my feet, providing effective relief for dry, cracked heels and ensuring lasting softness and hydration. I highly recommend these moisturizing socks to anyone looking for a comfortable and effective solution for foot care. They have become an indispensable part of my nightly routine, ensuring that I wake up with softer, healthier feet every day.

THESE THINGS SHED BAD!!!!!!!!!
Color: Pink Strawberries, Size: Regular
These things shed like you wouldn't believe. They're all over my furniture, my floor, my clothes. I'm finding little pink pieces of sock fluff everywhere and it's annoying. I don't think they did that until after I washed them. So if they don't shed on you right away, just wait, it'll most definitely happen. I returned because I won't where them again.

Keeping the crusty heels at bay!
Color: Cotton Gray, Size: Regular
I deal with chronic dry heels that crack if left unmanaged. I bought these in hopes that when I do soak and scrub my heels that I can keep the cracking at bay. These have been a godsend. I wear them every night and my heels are nice and soft. I plan on purchasing more. A couple of things I have noticed, if I wear these during the day, the bottom of my feet do seem to sweat and there is some slipping. I have only washed these are directed (hand washing) and you will want to after a couple washes because it could give a sweaty feet smell. Overall, I highly recommend.
