Motion sensor

Our motion sensor contains an ultrasonic transducer and works by measuring the time it takes a regular signal to travel between the sensor and a reflector. The measurement data can immediately be displayed as a graph by the MGA. There are two measuring ranges available for recording measurements: from 15 cm to 160 cm or from 0.4 m to 10 m with resolutions 0.5 mm or 2.5 mm

The sensor can be laid on a table or set up in a variety of ways on a stand rod. The sensor head can also be adjusted to various positions.

(The sensor is supplied with the MECHANICS 5 experiment set.)

Force sensor 

The force sensor can measure tensile and compressive forces and has measuring ranges of  ±10 N and  ±50 N with resolutions of 0.01 N or 0.05 N. It can easily be fitted to a stand and is especially well suited for displaying force in harmonic oscillations.

(The sensor is supplied with the MECHANICS 5 experiment set.)

Temperature sensor

The temperature sensor can measure temperatures ranging from -10 to +110 °C in steps of 0.1 °C with an accuracy of 1%. The 110 mm long stainless steel probe is resistant to acids, alkalis, salt solutions and organic liquids. The attached lead is 120 mm long.

(The sensor is supplied with the HEAT 3, the CHEMISTRY 7 and the BIOLOGY 7: PHYSIOLOGY experiment sets.)

Voltage sensor 

The voltage sensor has two measuring ranges ± 1 V and ± 6 V with resolutions of 0.002 V and 0.005 V and accuracy 1 %. It is suitable for both AC and DC voltage. To connect it to the MGA, a sensor connector cable is needed, while connection to the component for which the voltage is to be measured is via two standard experiment leads with 4-mm plugs.

(The sensor is supplied with the ELECTRICITY 5 and the CHEMISTRY 7 experiment set.)

Current sensor 

The current sensor has measuring ranges ± 0.3 A and ± 1.0 A with resolutions of 0.001 A and 0.003 A and accuracy 1 %. It is suitable for both AC and DC use. Like the voltage sensor, it is connected via a sensor connector cable and two experiment leads with 4-mm plugs.

(The sensor is supplied with the ELECTRICITY 5 and the CHEMISTRY 7 experiment set.)

Sound sensor 

This highly developed sensor can be used in conjunction with the MEKRUPHY ADDESTATION software to analyse various sound colours, to determine the lowest audible frequency, to measure speed of sound, to display beats and for the Doppler effect, among other things.

(The sensor is supplied with the ACOUSTICS 2 experiment set.)

pH sensor 

The pH sensor can measure pH values from 0 to 14 in steps of 0.1 pH with an accuracy of 1% following careful calibration. The sensor is pre-calibrated prior to shipping, but should nevertheless be re-calibrated from time to time using standard buffer solutions. The electrode is supplied in a bottle containing a special storage solution. It must not be kept in distilled or de-mineralised water.

(The sensor is supplied with the CHEMISTRY 7 experiment set and the BIOLOGY 7: PHYSIOLOGY experiment set)

Conductivity sensor

The conductivity sensor has three measuring ranges: from 0 to 200 mS/cm, from 0 to 2000 mS/cm and from 0 to 20 0000 mS/cm with an accuracy of 1% and resolutions of 0.1 mS/cm, 1 mS/cm and 10 mS/cm respectively. It can be used to measure the electrical conductivity of liquids, e.g. salt solutions of different concentrations.

Colorimeter 

This colorimeter is a powerful photometer, in which concentrations of solution can be determined. Three different wavelengths can be chosen. The solutions have to be filled in cuvettes. To ensure that the cuvettes were not covered by ambient light, they have to be put into the colorimeter.

(The sensor is supplied with the CHEMISTRY 7 experiment set.)

Dropper sensor 

This practical sensor counts on optical way the exact number of drops during a titration. The measure may be calibrated in volume values by means of the software. The sensor is easy to fix on a stand rod, moreover the pH sensor, the conductivity sensor and the temperature sensor can be added. Thus, the different measure ranges can be shown.

(The sensor is supplied with the CHEMISTRY 7 experiment set.)

Gas pressure sensor 

The gas pressure sensor can measure pressures ranging from 0 to 250 kPa in steps of 0.2 kPa with an accuracy of 2%. It is factory-calibrated and does not need to be re-calibrated thereafter.

(The sensor is supplied with the BIOLOGY 7: PHYSIOLOGY experiment set)

Carbon dioxide sensor 

This sensor was developed for measuring and recording the carbon dioxide content of gases. It can be used to investigate the carbon dioxide level of the air during breathing, photosynthesis or in the environment. The sensor can only be used in conjunction with the MGA and is supplied with a storage bottle and a sample flask. It is able to measure concentrations ranging from 0 to 50,000 ppm with an accuracy of 20%.

(The sensor is supplied with the BIOLOGY 6: PLANTS 2 experiment set)

Oxygen gas sensor

The oxygen sensor measures the oxygen content of gases from 0% to 27% O2 with a resolution of 0.01% O2 and an accuracy of 1%. It is not suitable for use in liquids. The sensor is factory-calibrated and does not need to be re-calibrated thereafter. Its housing is tailored to fit the neck of the gas sample bottle supplied with the PLANTS 2 experiment set.

Oxygen sensors have a limited life span due to the chemical processes involved. It can be significantly extended by being stored in a refrigerator, however. The MEKRUPHY ADDESTATION oxygen sensor has a two-piece design which means that only the chemically relevant part has to be replaced when it reaches the end of its useful life and not the entire sensor.

(The sensor is supplied with the BIOLOGY 6: PLANTS 2 experiment set)

ECG sensor

The electrocardiogram (ECG) sensor records an ECG for a person at three specific locations and transmits the signals using the MGA to the display for evaluation. Recording is done using one-way electrodes. The sensor comes with a special three-part cable.

(The sensor is supplied with the BIOLOGY 7: PHYSIOLOGY experiment set)

Stethoscope

The stethoscope allows heart sounds to be visualized and heart rates to be measured.
