As demand for multi-channel temperature recording for environmental protection, energy conservation and HACCP activities increase steadily, portability to enable measurement everywhere and at all times, and communications support for connecting to IT (information technology) networks are becoming indispensable capabilities for measurement instruments. Furthermore, at measurement sites, accurate measurements are required in severe conditions such as the presence of different electrical potentials, hum noise from commercial power lines, and switching noise from inverters. In response to these requirements, we have developed the new models with enhanced noise immunity from that of the former models.

Universal isolated temperature, voltage and pulse inputs, Universal measurement inputs, voltage, temperature (thermocouple and Pt inputs*1) and humidity*1,2 can be selected for each channel. In addition, four input channels are provided for measuring pulse inputs (totalization/rotation count) simultaneously with voltage, temperature and humidity. In addition to channel-to-channel input isolation, the PC connection interface is completely isolated from the measurement terminals. Shock hazard is minimized even when ther mocouples and voltage inputs are measured at the same time.
