Temperature Datalogger


The HI141 dataloggers represent the most economical and secure way of monitoring temperature continuously over long periods of time. These models are housed in a rugged, waterproof ABS casing that seals against the ingress of dust and water. The HI141 series offers the choice of one or two channels, internal or external temperature sensors, and an optional LCD.

•  Fully programmable
•  One or two channels
•  Store up to 16,000 readings

Features at-a-glance :

°C/°F Ranges
•  Through the PC application software, all HI141 models can be programmed to read in Celsius or Fahrenheit.

  Battery Error Prevention System (BEPS)
•  The Battery Error Prevention System will shut the meter off when the battery power is too low for an accurate measurement.

  Data Logging
•  The HI141 can store up to 16,000 measurements at selectable intervals from 1 second to 24 hours.
•  Users can also program a delayed logging start time up to 199 hours.

  Enhanced Battery Life
•  The HI141 series uses AA batteries to achieve a long battery life of about 4 years at 25°C.

  Internal/External Sensors
•  HI141 models that allow for an external temperature sensor feature one or two stainless steel probes on a 1 m (3.3’) cable for direct insertion.

LCD Display
•  The optional LCD is divided into 3 areas: the top displays the status of the datalogger; the middle displays the temperature reading, units, and active channel; the bottom displays
useful information regarding alarms, battery, sample number, and indicating icons.

Magnetic Start Key
•  Once all the settings are programmed using the PC software (for 32-bit systems), a convenient and portable magnetic start key can be used to initiate when data logging begins.
•  This helps users to quickly begin logging, preventing the need to access and start via the computer software.

One or Two Channels
•  HI141 dataloggers offer the option of one or two measurement channels.
•  Users can opt for one internal channel, one external channel, one internal and one external channel, or two external channels.

PC Connectivity
•  Logged data can be transferred to a PC by simply placing the instrument on the HI141001 infrared cradle (not included).
•  The infrared cradle eliminates the need to put a connector on the meter – an undesirable dirt-trap in the food market and source of problems due to wear and tear over time.
•  Using the cradle and software, users need just one PC interface to handle all HI141 dataloggers, each identi–fied by a unique ID code.
•  A security password is also able to be set to ensure collected data is tamper-proof.

  Programmable Alarms
•  High and low alarm thresholds can be programmed to alert users if the temperature readings go outside of the acceptable range.
•  The PC software (for 32-bit systems) can also indicate the length of time that temperatures remained unacceptable.

  Status Indicator Lights
•  The LED light located on the cradle blinks to indicate that communication with the PC is active during data transfer.

•  The case of the HI141 dataloggers is waterproof rated IP67. A convenient hanging hook is also located at the top of the housing on all models that end in “H”.
