COMTEST, local representative of Fluke is offering the Fluke 1551A Ex and 1552A EX “Stik” Thermometers, engineered to give temperature calibration specialists the durable, intrinsically-safe digital instrument they need for precision temperature calibration. The Fluke 1551A and 1552A “Stik” thermometers provide a highly precise and durable digital replacement for mercury-in-glass thermometers.
They are intrinsically safe (ATEX and IECEx compliant), so they can be used safely where potentially explosive gases may be present. More durable than mercury-in-glass instruments, they can be used reliably outdoors or on the production floor.
The 1551A “Stik” Thermometer covers a temperature range of –50 °C to 160 °C. The model 1552A Ex covers a range of –80 °C to 300 °C. Both models are accurate to ± 0.05 °C over their full temperature range. Process manufacturers of chemical, pharmaceutical, food or petroleum products require accurate temperature measurements.
Since temperature sensors are subject to drift with time, regular calibration or verification against a reliable reference thermometer is required. Finding a reference thermometer that is accurate, repeatable and robust was a challenge to the manufacturer.
