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.

Rotary motion logger sensor NUL-226

This sensor measures angles, rotations, rotation speeds or rotation acceleration. The sensor has a pulley connected to its shaft and the pulley rotation is measured. This sensor has four modes of operation: degrees, rev/s, rad/s, rad/s².

Force Plate logger sensor NUL-225

This module is in fact a weight scale designed for a multi range of purposes. Simply lay a heavy weight on its surface, or activate a forceful pressure against it (like a bouncing ball), and the logger sensor will measure it. But that’s not all, once a special set of handles are attached, it can also measure pull pressure rather than just weights and presses.

Flow logger sensor NUL-224

This sensor allows for a stream of water to flow through its inlet and outlet pipes, thus revolving a rotation wheel within it. The wheel is not connected mechanically to anything else, but rather floats on a bearing for minimum friction and the enhancement of its minute accuracy. The measuring is done by monitoring changes in the sensor’s surrounding magnetic field.

Drop Counter logger sensor NUL-223

This sensor enables to count automatically drops and bubbles. It is perfect for titrations. Combined with the pH sensor it gives a very nice titration curve.

The sensor comes with a pre calibrated value for the drops volume. The user can make his own calibration.

Blood pressure logger sensor NUL-222

The sensor measures the pressure in the cuff wrapped on the tested person’s arm.

Heartbeats affect the blood pressure. That is the reason for the difference between the systolic and diastolic pressure of the tested person.

The sensor has three ranges:

• The average pressure in the air pillow in mm Hg.
• The pressure beats in arbitrary units.
• The sum of the two above signals. This increases sensibility for the required calculations.

The NeuLog software extracts the following from the blood pressure graph:

• The systolic blood pressure
• The diastolic blood pressure
• The Mean Arterial Pressure (MAP) blood pressure
• The heart beat rate
