| Country of Origin | Made in India |
| Resolution | 10 Micro A |
| Current | 0-20mA |
Measurement of Magnetoresistance of Semiconductors
It is noticed that the resistance of the sample changes when the magnetic field is turned on. The phenomenon, called magnetoresistance, is due to the fact that the drift velocity of all carriers is not same. With the magnetic field on; the Hall voltage V=E t=|vx y H| compensates exactly the Lorentz force for carriers with the average velocity; slower carriers will be over compensated and faster one under compensated, resulting in trajectories that are not along the applied field. This results in an effective decrease of the mean free path and hence an increase in resistivity. Here the above referred symbols are defines as: v = drift velocity; E = applied electric field; t = thickness of the crystal; H = Magnetic field.
Experimentental Set-up for Magnetoresistance
The set-up consists of the following:
1. Four probe arrangement
2. Sample: (Ge: p-type)
3. Magnetoresistance set-up, DMR-01
4. Electromagnet, EMU-50V
5. Constant Current Power Supply, DPS-50
6. Digital Gaussmeter, DGM-102
(1) Four Probe arrangement°
It consists of 4 collinear, equally spaced (2mm) and individually spring loaded probes mounted on a PCB strip. Two outer probes forsupplying the constant current to the sample and two inner probesfor measuring the voltage developed across these probes This eliminates the error due to contact resistance which is particularlyserious in semiconductors. A platform is also provided for placing thesample and mounting the Four Probes on It.
(2) Sample
Ge Crystal (n-type) dimensions: 10 x 10 x 0.5mm.
(3) Magnetoresistance Set-up, Model VT-01
This unit consists of a digital millivoltmeter and constant current power supply The voltage and probe current can be read on the same digital panel meter through a selector switch.
(a) Digital Millivoltmeter
lntersil 3½ digit single chip ICL 7107 have been used. Since the use of internal reference causes the degradation in performance due to internal heating an external reference have been used. Digital voltmeter is much more convenient to use, because the input voltage of either polarity can be measured.
Specifications:
- Range : 0-200mV (100μV minimum)
- Accuracy : ±0.1% of reading ± 1 digit
(b) Constant Current Power Supply
This power supply, specially designed for Hall Probe, provides 100% protection against crystal burn-out due to excessive current. The supply is a highly regulated and practically ripple free dc source.
Specifications
- Current : 0-20mA
- Resolution : 10μA
- Accuracy : ±0.2% of the reading ±1 digit
- Load regulated : 0.03% for 0 to full load
- Line regulation : 0.05% for 10% variation
The details of other sub-units can be had from their respective data-sheets.

| Model Name/Number | VT 407 |
| Range | 40 to 400 mg/l as COD |
Because of dicromate ions specific oxidant properties, CrO ²-) unique chemical properties it gets reduced to the chromic ion (Cr³+) in COD test.
COD is a defined test, the extent of sample oxidation can be affected by digestion time, reagent stregnth & sample COD concentration.
COD is often used on a measurement of pollutants in waste water & natural water.
To determine COD two methods are useful, the open reflux method is suitable for a wide range of waste water & large sample size is prefferred. Another is the closed reflux method is suitable for smaller quantities. It requires homogenisation of sample. Accurate measurement of sample values as well as reagent volumes and concentration are critical.
