Compact and efficient alternatives to chart recorders and bulky data acquisition systems, the loggers are fully compatible with readily-available thermocouple probes in J, K, T, and S configurations.
Capable of monitoring temperatures up to 2,550° F. (1,400° C.), the units automatically scale the collected thermocouple data directly into your choice of degrees Fahrenheit or Celsius, eliminating the need for complex calculations or reference tables.

The loggers feature an on-board precision-calibrated thermistor sensor that provides cold-junction temperature compensation over the entire operating range, allowing you to use them accurately in harsh and demanding environments. Plus, each Spectrum Logger input channel is precision-calibrated during manufacture, eliminating any need for adjustment in the field.

Simple to set up and use, the data loggers require no programming or complicated equations.
To operate, simply select the type of thermocouple probe you are using, make your connections to the terminal block, and begin logging. The units are completely self-contained and self-powered, so you don’t need bulky transmitters, signal conditioners or external power sources, making them a convenient choice for remote in-field applications.

Available in single, dual and four-channel versions, Spectrum Loggers are ideal for high temperature process monitoring.
They are also well-suited for remote monitoring applications where reliable long-life battery operation is essential.

Introducing the Spectrum 2000 Temperature and Humidity data logger, a powerful and easy-to-use recorder that incorporates the latest advances in data logging and RH-sensing technologies.

Featuring an industrially-proven CMOS IC thin-film polymer RH sensor, the Spectrum 2000 delivers unsurpassed accuracy and convenience - all in a compact and dependable package. Designed for worry-free recording, it overcomes the drift, temperature error, hysteresis, and slow response times characteristic of other units, while offering outstanding resistance to airborne contaminants and condensation. So you can count on long-term maintenance-free monitoring - without recalibration. What's more, it's based on the advanced twelve-bit Spectrum™ logger platform so you'll be able to record even the most minute changes in temperature and humidity.

The Spectrum 2000 is perfect for verifying environmental conditions in offices, labs, computer and equipment rooms, museums, clean rooms. and storage facilities. It's also ideal for ensuring adherence to industry regulations and quality standards and for troubleshooting comfort, indoor air quality, and energy management problems.

Each Spectrum 2000 package includes everything you need to log, analyse and present your data. With its Windows-based software, detailed graphs, charts and printouts are just a few easy keystrokes away.
You can display your temperature graphs in °C or °F, and your humidity graphs in % RH.
You'll also be able to display ambient moisture in terms of dewpoint. enthalpy (btu/lb), humidity ratio (parts per million) and more, for the ultimate in analysis ease and flexibility.
