Respiration Monitor Belt logger sensor NUL-236

This sensor comes with a belt and measures the air pressure in it. The pressure changes according to the breathing of the subject. From the measured values, the respiration rate can be calculated.

Infrared Thermometer logger sensor NUL-235

This logger sensor measures temperature remotely using an infra-red high accurate sensor. It is very useful when access to the sample is either difficult or dangerous.

Wide Range Temperature logger sensor NUL-234

This sensor is based on a thermocouple sensor that enables measuring very high temperature levels, even the temperature of a flame, as well as very low temperature levels.

This sensor has two modes of operation: Celsius and Fahrenheit.

Surface Temperature logger sensor NUL-233

The sensor measures surface temperature. It can be put on any surface. It has two modes of operation: Celsius and Fahrenheit.

UVA logger sensor NUL-232

There are different wavelengths of ultra violet light. The UVA wavelength range is 315-400 nm, which is 98% of the total UV radiation. The UVA radiation affects photoaging and also photochemical smog. The intensity of this light is measured in mW/m² (milliwatt per square meter).

Turbidity logger sensor NUL-231

This sensor measures the reflected light that enters into a tube containing a solution. As solution turbidity is higher, more light is reflected and measured by the light sensor, located perpendicular to the light source.

The turbidity measurement units are Nephelometric Turbidity Unit (NTU).

UVB logger sensor NUL-230

There are different wavelengths of ultra violet light. The UVB wavelength range is 280-320 nm, which is 2% of the total UV radiation. The UVB radiation affects the vitamin generation in the human body, the immune suppression, skin cancer and cataract. The intensity of this light is measured in mW/m² (milliwatt per square meter).

Soil Moisture logger sensor NUL-229

This logger sensor is based on measuring the partial vacuum pressure in a tensiometer. A tensiometer is a closed tube with a special ceramic part in its end. The tensiometer is filled with water and put in the soil. If the soil is dry, water goes out by diffusion through the ceramic holes and partial vacuum pressure is created in the tensiometer. When we wet the soil, the partial vacuum in the tensiometer pulls water into the tensiometer and the vacuum decreases. This is why soil moisture is measured in pressure level.

Salinity logger sensor NUL-228

This sensor enables measurements of the salt content in a solution in three ranges: %, ppm and mg/L.

The sensor is pre-set factory calibrated and immediately ready to use.

Acceleration logger sensor NUL-227

This is a 3D (three dimensions) acceleration sensor which displays each dimension one at a time. It allows measuring the acceleration of moving bodies such as a body oscillating in a spring or in a moving vehicle.
