Soil Temprature Sensor Details

Item Name

IST01

Soil Temperature Sensor

Quick Overview

Soil temperature, moisture and sun play a key role in the germination of seeds and growth of plants. Heat works as catalyst for many biological process. For optimum growth continuous monitoring of soil temperature is important.

IST01 sensor is designed to measure soil temperature in extreme conditions. It can be directly inserted into soil. Because of its rugged and weatherproof design IST01 can be used in continuous outdoor applications.


Product Description

IST01 is precision integrated circuit temperature sensor and its output is directly proportional to the temperature. Stainless steel enclosure makes it rugged and protects the sensor from corrosion.

IST01 is precision integrated circuit temperature sensor and its output is directly proportional to the temperature. Stainless steel enclosure makes it rugged and protects the sensor from corrosion.

IST01 is easy to install and directly compatible with our IWS-A data loggers. It has analog output and hence it is compatible with other third party data loggers also.

Calibrated directly in centigrade with a liner scale factor it ensures a good accuracy of 0.5°C for full -55°C to 150°C scale.
