Gujarat-based Infra Control Systems (ICS) manufactures advanced portable data logging systems designed for maximum productivity. One software package operates all loggers in the range regardless of sensor type, range or calibration. A PC running windows with a spare serial port is all that is needed with this tiny logger system. Each logger is a self-contained intelligent computer eliminating the need to have separate programs for each logger type. Once set up via a PC, loggers can be disconnected and located remotely. Loggers operate independently until connected again for downloading of data. The user replaceable battery has a typical life of 1 to 2 years and non-volatile memory ensures data is secure even when the battery is removed. All readings are individually time and date stamped. For security each logger has a unique embedded serial number, which cannot be changed.
