This sensor measures electrostatic charges. It can be seen as a highly sensitive electroscope indicating whether a charge is positive or negative. Other uses are: to explore the nature of static charge, to measure both charge and voltage, to measure charge by induction, quantify the charge on a capacitor or discover the charge distribution on a conducting sphere.

Specifications:

Experiment Duration: 1 second to 31 days.

The NeuLog calcium sensor enables measurements of ionic calcium (Ca^₂+) concentration in aqueous samples. This measurement is very important when evaluating water quality. It can also be used to determine calcium – magnesium by EDTA titration.

Specifications:

Experiment Duration: 1 second to 31 days.

Logger sensor Guide

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:

1. The average pressure in the air pillow in mm Hg. 2. The pressure beats in arbitrary units. 3. 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:

a) The systolic blood pressure
b) The diastolic blood pressure
c) The Mean Arterial Pressure (MAP) blood pressure
d) The heart beat rate

Specifications:

Experiment Duration: 1 second to 31 days.

Logger sensor Guide

This logger sensor measures atmospheric barometric pressure and can display data in four common units.

• kPa – kilopascal
• atm – atmospheres
• in Hg – inches of mercury
• mm Hg – millimeters of mercury

The sensor also offers an option to display the measured pressure values in terms of altitude (in meters).

Barometric pressure can be measured at sea level (1 atm) and also on mountains (lower than 1 atm).

Specifications:

Experiment Duration:1 second to 31 days.

Ammonium measurements can also be very relevant to study the nitrogen cycle in general and to relate this cycle to plants and algae.

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.

Specifications:

Experiment Duration: 50 milliseconds to 31 days.
