The new SM150T is an affordable soil moisture and temperature sensor that is ideal for system integrators
SM150 Sensor � a versatile sensor for growers and system integrators
The SM150T is the perfect sensor for a wide range of applications in horticulture and agriculture. It can be used in both soils and substrates and is buriable. In addition, the SM150T offers excellent salinity and temperature stability.
The SM150T is a reliable and cost-effective solution for system integrators, who appreciate its ease of installation and simple interface (0 � 1 V DC output).
SM150 Kit � for instant readings
The SM150 Kit combines the SM150T Sensor with a handy readout meter, providing growers with a low cost, portable, and easy to use tool for obtaining instant accurate moisture measurements. Find out more about the SM150 Kit
NB: When used in portable mode the SM150T Sensor does not provide temperature indication. To record temperature the sensor must be fully buried and connected to a suitable data logger.
The SM150T뭩 sharp pins minimise soil disturbance, preserving the original soil structure around the measurement rods, and making the probe easy to insert and install. For burial at depth the cylindrical shape facilitates installation in augered holes. Optional extension tubes assist with placement and removal (50 cm and 100 cm lengths, connectable).
The SM150T Sensor is available (see SM150 Kit
) with substrate calibrations for perlite, coir, peat, and mineral wool, as well as soils � providing a simple, effective, rugged solution to checking the uniformity of growing conditions for many types of growing media.
Irrigation � Accuracy and ease of use make SM150T Soil Moisture Sensors well suited to irrigation applications. The SM150T뭩 compact size (143mm total length � rods 51mm long) allows it to be easily installed in plant pots or grow bags. Readings can be used to optimise irrigation scheduling, or the SM150T can be installed as part of an automatic irrigation system.
System integration � The SM150Ts accurate and stable measurement (� 3% for 0-70% VWC** range), simple 0-1 V output (moisture), and low power (18mA for 1 second) makes it the ideal sensor for system integrators.
Patented sensor electronics produce research-grade accuracy performance alongside exceptional salinity and temperature stability � an essential combination for critical control and irrigation decisions.
Industrial rated, UV resistant cable fitted with a waterproof IP68 connector allows the sensor to be buried indefinitely, whilst still permitting easy cable exchange or extension if necessary.
The SM150T is compatible with all Delta-T Devices Data Loggers and its 0 to 1 V DC output can be handled by most other types of data logger. Temperature measurement (10 K thermistor) requires burial of the probe.
The new SM150T replaces both the SM300 and SM150 Sensors, combining their strengths and offering great value.
