Description

Intrinsically Safe Temperature Data Logger, Fixed RTD, -50 To 160°C, 1/4×20 with Data Logging

The best substitute for precision mercury- or spirit-filled glass thermometers. The RTD probe and thermometer readout are combined into one unit and calibrated as a system. Intrinsically safe and accurate to ±0.05 °C over full range. The 1551A features a robust thin-film RTD sensor, ranges from -50 °C to 160 °C and primarily targets the petroleum industry. Of course many other industries have applications that require an easy-to-use, stable and portable reference thermometer and the “Stik” Thermometer is the perfect solution.

Features:

-50 to 160 °C
Accurate to ± 0.05 °C (±0.09 °F) over full range
Intrinsically safe (ATEX and IECEx compliant)
Display temperature in °C or °F
User-configurable temperature Trend/Stability indicator
Optional data logging to internal memory available
300-hour battery life
Percent battery-life and low-battery indicator
NVLAP-accredited, NIST-traceable calibration includedIntrinsically Safe Temperature Data Logger, Fixed RTD, -50 To 160°C, 1/4×20 with Data Logging
