  • Multi Use Low Temperature Data Logger
  • Interchangeable External Probe with high quality gold plated connector
  • Records temperature from +40°C to as low as -80°C
  • 'OK' & 'ALERT' Indicator with high and low alarm (user set)
  • 8000 reading memory capacity

The LogTag® low temperature external probe recorder measures and stores up to 8000 temperature readings over a measurement range of -80°C to +40°C (-112°F to +104°F) using interchangeable LogTag® ST10 External Temperature Probes. The LogTag® TREL-8 requires the ST10 External Temperature Probe and the cradle to function correctly.

Intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments.

Using the LogTag® Interface Cradle and the freely available companion software LogTag® Analyzer, the LogTag® TREL-8 is easily set-up for recording conditions including delayed start, sampling interval, number of readings, continuous or fixed number of readings and configuration of conditions to activate the 'ALERT' indicator.

LogTag® Analyzer also provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as MS Excel once the data has been downloaded.

Dear friends and representatives of the METERK brand

I have the Digital Clamp Meter equipment, Brand METERK, Model MK.06, but I lost the user manual in the Spanish language, (for my use and that of my technical representatives) I need the user manual, because I want to learn its best use and get to handle it very well, I consider this is a very good team ..
Please detail the capacitance measurement and the AC Voltage without connection.
