Thermco USB Ultra-Low Temperature Data Logger with LCD Display

The Thermco USB Ultra-Low Temperature Data Logger with LCD Display is an excellent device used for monitoring and recording ultra-low temperatures in freezers for blood plasma, vaccines, pharmaceuticals, and more.

Features:

• Comprehensive customisation options, including alarm settings, sample interval, and trip duration
• A real-time clock provides date/ time stamps for each temperature reading
• Inspections can be recorded at the push of a button
• It has a built-in audible alarm
• Easy-to-read LCD with 30-day summary in calendar format
• Auto-pause function - Unplugging the external probe automatically suspends alarm and statistics processing
• Interchangeable external probe with a high-quality gold-plated connector
• Made with a robust and durable polycarbonate case
• User-replaceable coin cell battery
• Includes NIST Traceable Certificate
• Comes with a 3m probe, LTI-HID interface cradle, and wall mount bracket

Technical Specifications:

• Temperature Measurement Range: -90°C to 40°C
• Operating Temperature Range: -30°C to 60°C 
• Storage Temperature Range: -10°C to 40°C
• Rated Temperature Reading Accuracy: Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration
  • Better than ±0.5°C for -20°C to 10°C
  • Better than ±0.7°C for -50°C to -20°C and 10°C to 30°C
  • Better than ±1°C for -80°C to -50°C and 30°C to 40°C
• Rated Temperature Reading Resolution: LogTag Analyzer currently displays to one decimal place of °C. The native resolution is what is stored in the LogTag®
  • 0.1°C for measurements -80°C to 0°C
  • 0.2°C for measurements 0°C to 18°C
  • 0.3°C for measurements 18°C to 30°C
  • 0.5°C for measurements 30°C to 40°C
• Memory: 15,905 temperature readings. 66 days at 6-minute logging
• Sampling Interval: Configurable from 30 seconds to hourly
• Logging Start Options: Push button start or specific date and time. Optional start delay of up to 18 hours
• Download Time: Typically less than 10 seconds for full memory, depending on the computer or readout device used
• Power Source: 3V CR2032 (LiMnO2) coin cell battery, user-replaceable
• Battery Life: 1 year storage, followed by 1 year of operation with normal use (6-minute logging, statistics reviewed on the display no more than once daily for no longer than 30 seconds each time, download data monthly)
  NOTE: Continual activation of the audible alarm will reduce the working life of the battery. When an alarm is triggered, the alarm should be cleared and reset as soon as possible
