1. Įvadas
The Extech Instruments HW30 HeatWatch is a multi-function stopwatch designed to provide essential environmental data alongside precise timing capabilities. This device displays digital up/down timer functions, current temperature, humidity, and calculates the heat index, which indicates how hot it feels when humidity is combined with the actual temperature. It is an ideal tool for monitoring conditions in various environments, particularly those with hot weather. Additional features include a 12/24-hour clock, a standard stopwatch, 30 lap/split memory, and a programmable alarm.
