5577 - 

The 5577 provides basic accuracy of ±0.05 oC over its full range of -100 oC to 135 oC. In addition, each 5577 system (meter and probe) comes calibrated over its full range by Hart Scientific, 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.

The 5577 is rated for intrinsic safety by CENELEC in Europe and has the following rating: EX II 2G EEx ib IIB T4. This intrinsically safe thermometer is a critical instrument for petrochemical refineries that have mainly relied on delicate liquid-in-glass thermometers for temperature measurements. It's also a valuable device for natural gas firms, which, in custody transfer applications, must take precise temperature measurements to ensure volume accuracy.
