The Fluke 1551A and 1552A
“Stick” Thermometer Readouts
are an intrinsically safe digital
substitute for your mercury-in-
glass thermometers. Accurate and
repeatable to ± 0.05 °C over their
full range, the 1551A and 1552A
are the “gold standard” of indus-
trial temperature calibration.
Whether working outdoors in
environments where potentially
explosive gases may be present or
on the floor of a processing plant,
the intrinsically-safe, battery
operated, portable reference ther-
mometer is designed to go where
you work.
Summary specifications:
• Accuracy of ± 0.05 °C (± 0.09 °F) over full range
• Intrinsically safe (ATEX and IECEx compliant)
• Two models to choose from (-50 °C to 160 °C or
-80 °C to 300 °C)
The 725Ex is an intrinsically
safe multifunction process cali-
brator for usage in areas where
explosive gases are known to
be present. This calibration tool
sources and measures almost all
process parameters. Measure and
source temperature (RTDs and
thermocouples), volts, mA, fre-
quency, ohms, and pressure, using
optional pressure modules.
Summary specifications:
• ATEX II 1 G Ex ia IIB 171°C KEMA 04ATEX 1303X
• CSA Class I, Division 1 Groups B-D,
171 °C compliance
• Source and measure 12 different
thermocouple types
• Source and measure 7 different RTD types
• Source and measure mV and resistance
for testing custom temperature sensors
