The TOMST Soil Moisture and Temperature dataloggers offer a reliable way to measure soil moisture, as well as air and soil temperature, using three temperature sensors and one soil moisture sensor. Their high-capacity lithium battery provides an approximate lifespan of 10 years. Combined with large internal memory capable of storing up to 524 288 records, each TMS logger operates autonomously and requires minimal maintenance. Their low cost and robust construction make them suitable for long-term monitoring over large areas, including harsh conditions.

A potentiometer-based point dendrometer for precise automatic measurement of stem diameter changes with sub-μm resolution. It also measures air temperature through an integrated thermometer. Its robust construction, large internal memory, and high-capacity lithium battery make it suitable for long-term deployment in harsh outdoor conditions with minimal maintenance.

A durable, autonomous thermologger based on the TMS datalogger design, built for air temperature monitoring across a wide range of conditions. It uses a single temperature sensor and is compact enough to be hung on trees, fixed to structures, buried in soil, or placed almost anywhere outdoors for long-term data collection. Data is stored internally and can be quickly downloaded when needed.
