Detailed Temperature Profile

The HI148 Series Waterproof Thermologgers automatically log your results with programmable logging intervals from 1 second to 24 hours for 1-channel models, and from 2 seconds to 24 hours for 2-channel model. The thermologgers feature extensive memory capacity: 16,000 samples for 1-channel models and 8,000 samples/channel for 2-channel models. Storing temperature at logging interval, or min or max temperature between logging intervals


Versatile Data Logging

Using the HI92148 PC software the HI148 can be programmed to store temperature readings at a specific logging interval, set upper and lower alarm limits, and delay logging from 1 second to 199 hours. There is also a log start button to ensure you only measure what you need.
