Temperature USB Data Logger with LCD

Product Code: HDT-220

Measure and store up to 16,378 temperature readings over a -35°C to +80°C (-31°F to +176°F) range.

The high contrast 2½ digit LCD can show a variety of temperature and humidity information at the touch of a button: cycle between the current, maximum and minimum stored temperatures.

The HDT-220 data logger is supplied with a long-life replaceable lithium battery which can typically allow logging for 1 year (depending on logging rate, ambient temperature and use of alarm LEDs). Status is indicated by flashing red, green and orange LEDs.

Easily configure the data logger by plugging it into a PC's USB port and running the free EasyLog USB software, available for download using the link below. Configuration options include: logger name, measurement unit (°C or °F), logging rate, high/low alarm levels and start date/time. Logged data can be downloaded via the software and then graphed, printed or exported to other applications.

The unit is protected against moisture to IP67 standard when the supplied protective cap is fitted.
