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 1m (3.3ft) 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 can be set anywhere up to 199 hours. The MIN or MAX 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. A long-life AA lithium battery provides power. For a typical 1 minute logging interval, your battery will last about 4 years.

Note: Models with a longer cable for external sensors are available upon request.
