The Fluke 1551A-9 "Stik" Thermometer provides all of the features of the 1552A but with a narrower temperature range—50 °C to 160 °C (-58 °F to 320 °F). The Fluke 1552A delivers repeatable temperature measurements accurate to ±0.05°C over its full range. It is rated intrinsically safe for working in indoor or outdoor environments where potentially explosive gases may be present. It's a great choice for environments that aren't potential explosive as well such as the floor of a processing plant. The battery operated, portable reference thermometer is a great choice for daily checks of working thermometers, custody transfer temperature determination, PET calibration, LIG calibration, and temperature transmitter calibration and verification.
