Portable reference thermometer

Sunday, 26 October, 2003 | Supplied by: Fluke Australia Pty Ltd


Capable of operating in specified hazardous environments, the Model 5577 intrinsically safe handheld reference thermometer has been launched. The Dostmann manufactured 5577 meets the demand for ATEX certified electrical equipment in potentially explosive atmospheres.

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) comes calibrated over its full range. This provides for NIST traceable and 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. With a permissible maximum surface temperature of 135°C, the product is suitable for all areas except for mining environments.

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 is also a suitable device for natural gas firms, which, in transfer applications, must take precise temperature measurements to ensure volume accuracy.
