Weather can have a dramatic impact on contractors and its adverse effects can result in heavy costs. Monitoring forecasts can help limit the issues, but forecasts can come from locations at a fair distance from the construction site. Richard Paul Russell Ltd, the official UK distributor for Kestrel Weather & Environmental Meters, offers the 4300 Construction Weather Tracker, developed just for the concrete industry. It delivers a full list of weather parameters including evaporation rate to help manage and minimise plastic shrinkage cracking.
The Kestrel 4300 is a hand held unit weighing no more than a mobile phone, incredibly robust and waterproof it can be located on a tripod and will log data for records. The unit measures wind speed, temperature and relative humidity amongst other parameters and uses the temperature of the concrete (which you input) to calculate an evaporation rate. Understanding this prior to concrete laying or coatings applications ensures informed decisions can be taken concerning the suitability of environmental conditions.
