Traceable Instruments

When a measurement has to hold up to an audit, Traceable instruments from Cole-Parmer earn their name: each device ships with calibration documentation traceable to standards maintained by N.I.S.T. That paper trail is the reason labs, pharmacies, clean rooms, and quality departments reach for this line — it's not just about reading a number, it's about being able to prove that number is right.

This collection covers the environmental monitoring and timing tools that keep controlled spaces compliant. The Traceable Digital Thermometer/Hygrometer (4040) tracks both temperature and relative humidity on a triple display, reading 32°F to 122°F with ±1°C and ±4% RH accuracy. Its internal sensor and flip-out stand or wall-mount design suit fume hoods, storerooms, incubators, drying chambers, and environmental cabinets — anywhere humidity and temperature drift can spoil samples or void a batch. For workflows that hinge on timing rather than climate, the Traceable Electronic Alarm Timer (5028) manages up to three separate holding periods across a 100-minute range, so staoff can stage multiple procedures without a second device.
