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.

Good replacement parts and affordable
I acquired this filter set to replace the OEM filters in my wife's Honda Accord. The filters fit perfect and were easy to install. Normally when I replace filters I have to purchase both the air filter and the cabin filter separately. In this case, it was very nice to have them sold as a combo set. While I don't know what materials are used to manufacture these filters, I will say that the air filter looks just like the OEM part in terms of it's production. The cabin filter does have carbon built in to help control orders, which is something the OEM part did  not have, so it looks different in terms of filter color. I normally replace filters every 10K to 15K miles, and this fits in line with that this manufacturer suggests (every 12K miles).  In all, a decent combo set of filters helps keep costs down and both filters can be replaced at the same time.

Perfect!!!
This is exactly what I needed. Fits perfectly for my 2018 Honda Accord as well as being very easy to install. This is coming from someone who has no idea about doing anything on my car. Provides the best function, just as it would coming from a dealer or other auto shop. The quality is great as well, and this is exceptional value for the money. If you are looking to save money and not get bombarded with the filter replacement question when getting an oil change then this is the one for you.

Fit is good.
Filters fit and look essentially the same as the filters I’ve purchased and the official types from the dealer. I live in an area where wildfires occur almost every year,  so it’s good to have an extra set of filters to change them out after a run of smoky days.
