HI 141 - Temperature Dataloggers with Internal and External Sensors

The HI 141 series is a family of temperature data loggers with either one or two channels, internal or external temperature sensors, and an optional LCD. External temperature sensor models feature one or two stainless steel sensors on a 1 meter (3.3') cable for direct insertion. HI 141 can store up to 16,000 temperature samples in a protected, non-volatile EEPROM memory. The logging interval can be set from once per second, up to every 24 hours, and logging delay start can be set anywhere up to 199 hours. The MIN orMAX temperature between logging intervals can also be stored. All of your collected data is tamper-proof and stored into serial numbered lots. The user interacts with the logger, setting data acquisition parameters or downloading logged data, through an RS232 serial port on a Windows® PC. The HI 141000 Windows® compatible software supports communication between the logger and the PC through the HI 141001 infrared transmitter. The housing is waterproof and can include a convenient hanging loop (simply add an "H" to the end of the code). A long-life AA lithium battery provides power. For a typical 1 minute logging interval, your battery will last about 4 years.

HI 142 • HI 504903 - A Complete System for Temperature Monitoring from PC, Cellular Phone and Modem

In food industry applications, such as catering and supermarkets, temperature monitoring, recording and control are becoming more and more critical. Several regulations require hard copies of temperature data from production all the way through to the consumer. For this reason many instruments have been produced for continuous temperature monitoring, but they usually have to be removed from their location for data downloading. Now, thanks to the advanced technology of our HI 142 and HI 504903, this is no longer a problem. HI 142, available in 8 models with different temperature ranges, allows data downloading directly to the PC. You can interact the loggers directly from your PC, perform set-up, check the status of the instruments and download the data when the logging is complete.

You can choose between two connection types: direct connection between PC and HI 142/HI 504903 system, or modem connection which allows logger supervision from a distance of several kilometers. It is possible to build a control network with up to 31 loggers. If an error occurs in one or more loggers, e.g. measured temperature is outside the set limit or in case of power failure, HI 504903 will advise the user by sending an SMS to the programmed phone number(s). The message will contain the logger ID and the error. If the HI 504903 does not receive any confirmation of received SMS, it will continue to send messages and call the user. The operator can also check system status by calling the HI 504903 GSM supervisor, that will answer with an SMS for each logger. The message will include the operating status (stand-by, logging), any recorded error and the current temperature.
