The TWL-1S is used to monitor and assess thermal risk levels indoors and outdoors. It has a smart user-friendly interface that allows users to instantly identify the thermal risk level result based on different colors. Users can also do data logging directly by connecting the device to Windows PC via the USB cable. Wireless pager for a remote alerting system is available for the TWL-1SR model. The TWL measures air temperature, humidity, radiant heat, and wind speed to come up with instructions for work, rest, and hydration plans. 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 were in line with the TWL schedule. For example, red means unsafe for work, yellow means buffer zone, and green means safe for work. FEATURES ● Smart User-Friendly Interface: Meters were supposed to sense the targets and give readings. Scarlet intends to do more. TWL theory determines the threshold for a safe, fair, and dangerous working environment. Colorful LCD backlight tells you the risk level based on the TWL value. Work-rest schedule and fluid intake are integrated into the display. A countdown timer shows the time remaining before a recommended rest. ● Automatic Warning: The working timer starts counting according to the TWL value. When it expired, the device will notify the pager carriers remotely. It reminds you to take action. 433 MHz technology is used to offer better penetration ability and 200 meter coverage in an open area is achieved. Please note that pager is available in the TWL-1SR model. ● Sensor Protection: Delicate temperature and humidity sensors are well protected by a replaceable polypropylene (PP) filter in a solid shield, exempting the sensors from dust damage and external strike. A silicone pad protects the mechanism of the anemometer from dust. WHERE DOES SCARLET TWL-1S APPLY? ● Construction Sites● Tower Cranes● Outdoor Events● Port Terminals● Chemical Pl
