Palmer Wahl Instrumentation Group’s Wahl DST500-FM temperature indicator with fixed probes is a high-accuracy, wide-range thermometer designed for hazardous locations where accurate and reliable temperature monitoring is critical. Fixed-stem probes are available in straight or 90° back-, left-, or right-angle connection from either 304 or 316 stainless steel. The four-wire RTD has a total system accuracy of ±0.3°F for temperatures less than 300°F and ±0.25% of reading for temperatures greater than 300°F over a one-year period. Temperature range is -328°F to +1472°F. The 1-in, four-digit LCD display is readable from 30 ft, with resolution of 0.1°F (1°F above 999.9°F).
