Microstar™ USB Temperature Data Logger

• Single-use and easy to activate
• No additional software/hardware required*
• Temperature Range: -30°C to +70°C (-22°F to +158°F)
• Full data report provided including graph and data points

Microstar™ USB Temperature Data Loggers provide an inclusive solution for monitoring temperature sensitive products. These single use devices are quick to activate and protected in waterproof packaging to ensure unit integrity during use. 10 minutes after activation the logging begins and will continue recording up to 90 days.

To access logger data, simply remove from the sealed package and insert into the USB slot of your computer. No additional software or hardware is required. A fully detailed PDF report is generated automatically and includes specific logger information, temperature graph and data points. All loggers use Universal Coordinated Time (UTC) as the reference for date and time data.

Each logger is tested and validated by an accredited laboratory and traceable to NIST.

WarmMark™ Short-Run Temperature Indicators

• Single use and easy to activate
• Shows temperature exposure above the indicator set point
• Brief, moderate, prolonged exposure times

The WarmMark family of temperature indicators are single-use devices that provide accurate, irreversible evidence of any above temperature deviation allowing you to make smarter decisions across the cold chain. The WarmMark ascending time-temperature indicator alerts users of exposure to unacceptably high temperature conditions and the cumulative amount of time of the exposure.

WarmMark Product Features

1. Field-armable with pull tab
2. Temperature sensitivity
3. Black stripes show product armed
4. Brief, moderate, prolonged exposure times

ColdMark™ Time Temperature Indicators

Some temperature sensitive products must never be exposed to temperatures below freezing. The ColdMark™ Freeze Indicator is a single-use, self-activating tool that tells you if your product has been exposed to freezing conditions. When the temperature dips below a freezing point, the clear, colorless indicator bulb changes to a violet color. This color change cannot be reversed, even if the temperature rises back up above freezing.
