Does Transcat Support Temperature Recorder Functions?

Temperature recorders, also known as temperature chart recorders, have built-in digital hygrometer capabilities with the potential to record large amounts of data, and can capture and store pressure, humidity, and temperature details. Their applications include plant maintenance, heat treatments, and the chemical industry.

  • Transcat calibrates temperature chart recorders and hygrometers in humidity calibration labs strategically located in the U.S., Canada, and Puerto Rico
  • For chart recorder calibrations, we offer reference-level capabilities in a number of labs, with humidity standards up to 95% RH using a Thunder Scientific chamber
  • Our highly skilled technicians can perform in-process or onsite calibration services at your location
  • We recalibrate temperature recorders and thermo-hygrometers designed for calibration labs and scientific settings

High Accuracy Hygrometer Calibrations

Do you have elevated standards when it comes to calibration services? Transcat can meet those standards as we calibrate hygrometers according to stringent quality processes. Every humidity calibration service we perform in our ISO 17025-accredited calibration labs is ISO-9001 compliant, with true traceability to SI Units through NIST, equivalent sources, or physical constants. You can trust our world-class North American network of calibration laboratories to successfully service your environmental instruments!
