The Tc-LCD is a high resolution (16 bit), handheld thermocouple datalogger with a liquid crystal display. The logger connects to a single external thermocouple probe and also has an internal thermister sensor. The logger accepts Type J,K,N,R and T thermocouple probes. The display shows ambient temperature, thermocouple temperature, battery voltage, logger and alarm status. This logger is designed for indoor use (IP 40) but can be supplied with a TruTrack Seahorse Logger Enclosure for outdoor use. The logger uses the standard NIST (National Institute of Standards and Technology) equations to calculate, display and log temperatures from the various thermocouple probe types |
