Portable reference thermometer provides intrinsic safety

27 August 2003 Test & Measurement

Spescom MeasureGraph offers the new model 5577 intrinsically safe handheld reference thermometer from Hart Scientific. The 5577 is a portable reference thermometer capable of operating in specified hazardous environments.

This intrinsically-safe thermometer is a critical instrument for petrochemical refineries that have mainly relied on inaccurate readout devices or expensive and delicate liquid-in-glass thermometers for temperature measurements. It is also a valuable device for natural gas firms, which, in custody transfer applications, must take precise temperature measurements to ensure volume accuracy.

The 5577 provides basic accuracy of ±0,05°C over its full range of -100 to 135°C. In addition, each 5577 system (meter and probe) is calibrated over its full range before delivery, providing a NIST-traceable NVLAP-accredited system calibration.

The 5577 has two inputs and can display either simultaneous side-by-side readings from both inputs or the differences between the two inputs for easy comparisons.
