Nitrate logger sensor NUL-241

The NeuLog nitrate sensor can be used to measure the concentration of nitrate ions (NO₃^–) in aqueous samples. Nitrates are used in fertilizers and can contaminate water. Also, untreated human sewage can be a source of nitrate contamination. Nitrate measurements can also be very relevant to study the nitrogen cycle in general and to relate this cycle to plants and algae.

Ammonium logger sensor NUL-240

The NeuLog ammonium sensor can be used to measure the concentration of ammonium ions (NH₄⁺) in aqueous samples. It can be used to evaluate the degree of contamination of water due to the use of fertilizers.

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

Chloride logger sensor NUL-239

The NeuLog chloride sensor can be used to measure the concentration of chloride ions (Cl^–) in aqueous samples. This measurement can be an indication of the salinity of water samples. The sensor can be used to study samples of drinking water with different degrees of chlorination.

Calcium logger sensor NUL-238

The NeuLog calcium sensor enables measurements of ionic calcium (Ca²⁺) 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.

Hand Dynamometer logger sensor NUL-237

This sensor comes with a hand held unit with a built in strain gauge. The sensor measures the pressing force on the hand held unit.

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).
