176 T4 4-Channel Temperature Data Logger with DisplayThe testo 176 T4 temperature measuremt logger with bright, baciklit display makes it ideal for the monitoring of temperatures. The 176 T4 temperature data logger has external thermocouple parallel connections, which allows for simultaneous temperature measurements at four sites using a wide variety of probes. Creation of Excel Spreadsheets, PDFs, and data analysis are all easily achieved with the free, downloadable ComSoft software.This measuring instrument needs a probe for being commissioned.Includes176 T4 temperature data logger with external parallel connectionsBatteriesCertificate of conformitFeaturesExternal thermocouple parallel connections provide reliable temperature monitoring at up to four sitesLarge, easy to read, bright, and backlit display makes it easy to see the current temperatureLarge data memory capable of storing 2,000,000 temperature readingsRugged and waterproof according to IP54The testo 176 T4 temperature measurement logger is an ideal data logger for the monitoring of temperatures.External thermocouple parallel connections compatible with a variety of different probesData transfer possible using the USB port, or SD card (Optional)Easy to read large display that shows current readingIP54 protection classCapable of CFR 21 Part 11 CompliancyFree data logger software available for downloadData is secured within the logger, and can be password protected using ComSoftChecking the flow and return temperature of heating systemsThe heating period starts in autumn and with it the time for tenants to complain that the apartment cannot be heated to the extent they want as well. Using flexible external pipe wrap probes, you can for instance check the flow and return temperature of individual heaters in a targeted way, so as to identify causes and remedy them.Checking the temperature in super freezers or under cryogenic conditionsSpecific products must be stored under extremely cold conditions so as to ensure their quality. Therefore, in many laboratories and research facilities you can for instance find super freezers which can be cooled down to -80 °C using liquid nitrogen or dry ice. In many cases storage under cryogenic conditions is even required. So, particular biological or blood products are for example stored and transported at -196 °C. Special measuring instruments, which are also fit for purpose at such low temperatures, are needed to check these extreme conditions.Monitoring process temperaturesFor production quality assurance, the temperature must frequently be checked at various points in production processes. Whether it is the air temperature, the temperature of production items themselves or the surface temperature of machines or motors. Using thermocouple probes, data loggers can also record data in the kinds of extreme temperature ranges that are often to be found in production processes. The probe's fast speed of response contributes here to a good measurement result being achieved even in processes where temperatures change quickly.
