1551A Ex and 1552A Ex Stik thermometers

The 1551A Ex and 1552A Ex Stik thermometers provide a precise and durable digital replacement for mercury-in-glass thermometers.

They are intrinsically safe, being ATEX and IECEx compliant, so they can be used safely where potentially explosive gases may be present. More durable than mercury-in-glass thermometers, they can be used reliably outdoors or on the production floor.

The 1551A Ex Stik thermometer covers a temperature range of -50 to 160°C. The model 1552A Ex covers a range of -80 to 300°C. Both models are accurate to ±0.05°C over their full temperature range.

The stainless steel probe and digital readout of the both thermometers are fixed together and calibrated as a system. The accuracy specification is easy to understand since it includes all uncertainty components, including drift, for up to one year. The large backlit LCD rotates 90°, making it easy to read from any angle.

A user-configurable stability/trend indicator lets the technician know when the temperature is stable enough to record an accurate measurement. A user-settable auto-off function extends typical battery life to 300 h. A low-battery indicator and stop-measure function prevent erroneous measurements from being made due to low battery life. A simple three-point calibration function lets users easily and accurately calibrate the thermometer. Data logging to internal memory of up to 10,000 time-stamped measurements is optionally available.
