Extech's new 42280A Series Temperature and Humidity Data Logger features a number of notable improvements over the company's successful previous model, to ensure even higher levels of performance and capacity in indoor environmental monitoring applications. This latest-generation data logger, very accurate and reliable, will be a valuable asset for any company seeking, for example, to monitor the air quality of its production area.
A direct replacement for the popular 42280 series, the new 42280A features the same large LCD display that simultaneously displays temperature, humidity and date/time. With continuous improvement in Extech's DNA, the company's new model features a number of value-added features, including the ability to generate PDF reports or Excel spreadsheets by connecting the device (via the built-in USB interface) to a Windows PC after data is logged.
Another important improvement is that the internal memory is increased to 48,000 points/reads, three times more than the previous model, in order to meet requests for prolonged monitoring or high frequency rates. The Extech 42280A also sees the introduction of a Max/Min mode and the presence of an on-screen up/low indication. Here, the programmable/selectable data sampling rate ensures a visual and audible alarm indication in combination with the high/low limits.
Adaptable to almost any situation, the new Extech 42280A has other features, including a "marking" function to read the contents of the memory from a specific moment without reprogramming the register. Note that the data remains secure in the logger at all times and can be protected by a password if necessary.
Extech is also launching its new version 42280A-Nist. This model features traceability to NIST standards for indoor environments where it is necessary to demonstrate measurement accuracy and reliability, with calibration reports downloadable to a PC.
Essential components of any indoor environmental monitoring system, the 42280A and 42280A-Nist data loggers both offer a temperature range of -20 to +70°C and a humidity range of 0 to 100%. The devices measure only 120.7 x 88.9 x 38.1 mm and weigh only 163 g. Users can choose a wall mount, desk mount or tripod according to their needs. Salt bottles for relative humidity calibration are available as a kit (33% and 75%) as optional accessories.
Extech provides the 42280A and 42280A-Nist with Windows-compatible software, USB cable, universal power adapter, four AA batteries, user guide and two-year warranty for complete peace of mind. The devices are delivered fully tested and calibrated and, when used correctly, will ensure years of reliable service.
