LSI Heat Shield

Heat Shield is a compact unit that includes a single body the sensors of radiant temperature, wet bulb temperature, temperature and Relative Humidity of air for the calculation and display on integrated display of the WBGT indoor & outdoor indices.


Kestrel 5400

The Kestrel 5400 is revolutionary in size, cost and capability for those in need of measuring Heat Stress. Available with or without LiNK (Bluetooth) and / or a compass.

Along with having a Wet Bulb Global Temperature reading, the Kestrel 5400 displays thermal work limit (“TWL”), another recognized composite heat stress prediction tool. For both WBGT and TWL, the Kestrel 5400 provides on-screen alarms when conditions enter the caution and danger zones, providing clear and immediate guidance that heat illness prevention steps must be taken. Clothing levels can also be customized, making the Kestrel 5400 particularly useful in activities requiring heavy protective gear which worsens heat stress. The Kestrel 5400 also displays natural wet bulb temperature, and black globe temperature.


Scarlet TWL 15

Scarlet TWL-1S is designed to measure WBGT and thermal work limit (TWL) heat index. The TWL measures air temperature, humidity, radiant heat and wind speed to come up with instructions for work, rest and hydration plan. We integrate the algorithm of TWL and work-rest schedule based on the latest guideline. The user-friendly interface even showed different colors to ensure users in line with TWL schedule. For example, red means unsafe for work, yellow means buffer zone and green means safe for work.


Kestrel Drop

First Waterproof, Rugged, Wireless, Environmental Data Logger measuring temperature, humidity and pressure. Monitor and record the conditions of indoor and outdoor environments and easily access real-time as well as historical data on your phone or tablet through a Bluetooth Smart connection to the Kestrel LiNK app.


Delta Ohm Network

A network of instruments that record and monitor various environmental measurements such as Relative Humidity and Temperature.
