Temperature and Humidity Logger for Explosive Environments
fourtec's popular MicroLog, which logs temperature and humidity, has now been approved Intrinsically Safe for use in explosive environments including surface and underground gas and dust, methane and coal dust, propane to hydrogen. This means it is perfect for monitoring the working conditions in underground mines and other hazardous locations. You can now be sure that workers are not being subjected to excessive environmental stress.
Weighing 55g and 72mm in diameter, the MicroLog is water and dustproof to IP65. It is therefore an ideal monitor for an individual or groups of workers. The battery lasts for 2 years when sampling at 15-minute intervals and the memory capacity is 16,000 samples.
The MicroLog continuously measures and displays environmental temperature and humidity with min/max function while logging trends. You can program each MicroLog with its own identifier and the logged data is downloaded to your PC with one click of the mouse! It is the smart way to care for the health and safety of your workers.
