The EnviroLog is a single-use, cost effective & reliable temperature recorder with an integral USB connector. It measures and stores real time temperature readings over a measurement range of -30 °C to +70 °C.

The EnviroLog automatically generates a PDF report which requires no special software and combines all the features of an advanced temperature recorder with an 16,000 log memory and a 6-month operating life.

Temperature Sensor Measurement range -30 °C to +70 °C (-22 °F to +158 °F)
Recorder operating temperature range -30 °C to +70 °C (-22 °F to +158 °F)
Storage Temperature Range 0 °C to +40 °C (32 °F to +104 °F)
Rated Temperature reading accuracy Better than ±0.5°C (±0.9°F) for -5°C to +30°C (23°F to +86°F). Better than ±0.8°C or better for measurements in other areas of rated range. Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration
Rated Temperature Reading Resolution Better than 0.1°C or 0.1°F. The native resolution is what is stored in the EnviroLog ®
