Sper Scientific* 4 Channel Datalogging Thermometers

This thermometer has the ability to automatically record and store up to 16,000 data points on each of the 4 channels in the field which can later be downloaded to your computer. Real Time Data can also be logged while connected to your computer. These unique portable thermometers display data from 4 thermocouple probes simultaneously on a large back-lit LCD. Communicates with a computer via the bi-directional RS232 port and optional cable, and graphic software. Auto ranging with auto power off, min./max., hold and relative functions. High full scale accuracy of +/-0.5% rdg. + 1°C / 2°F. Easily calibrates to ice point, or any other standard. These meters come ready to use in a protective foam lined case, with 2 beaded wire probes (Ambient Type K probe, Cat. No. 350-98779), RS232 computer cable (Cat. No. 330-52228), software (Cat. No. 350-98830), and a 9V battery. Cat. No. 350-98851 includes a NIST traceable certificate of compliance.
