Dry ice data logger MSR85 for ultra-low temperatures
MSR85: Reusable PDF Ultra-Low Dry Ice Temperature Data Logger down to -85 °C for Temperature Monitoring of Cold Chains and Shipments
The robust MSR85 data logger ensures reliable temperature monitoring for products transported or stored with dry ice.
The perfect solution for monitoring the transport of sensitive goods such as pharmaceuticals, vaccines, biological samples, tissues, and enzymes requiring a secure cold chain down to –85 °C.
Reusable. Reliable. Tamper-proof reports.
Thanks to its replaceable battery and long operating life, the MSR85 is reusable – a cost-effective and sustainable solution for cold chain monitoring. Set-up is remarkably simple: Before use, configure all required parameters such as alarm limits, measurement interval or time zone using the Configuration Tool. Recording is then started conveniently with the push of a button.
After transport, recipients can immediately see via the LED whether threshold values have been exceeded. Once recording is stopped by pressing the button, and the logger is connected to a PC via USB, the MSR85 automatically generates tamper-proof PDF and CSV reports with all relevant data.
