Scientific equipment and services and techno instruments are both iso 9001: 2000 certified company engaged in manufacturing of complete laboratory experiments measuring instruments for bs and ms laboratories of physics, electronics and electrical engineering.
The company manufactures a number of laboratory instruments.
Digital nanoammeter, dnm-121, is a rugged and low cost instrument, is a product of extensive research and development using high input impedance integrated circuits. It has 4-decade ranges with 100% over-ranging. The unit is suitable for current measurement in the range of 100pa to 200µa. For the ease, readings are directly obtained on a 3½ digit dpm. The instrument is capable of accepting either polarity of the input current.
The very low leakage current of the input stage combined with the high linearity fast response due to high negative feedback enables accurate and easily reproducible measurements. The instrument uses a fet input operational amplifier that offers the very low input bias current, low offset voltage, low drift and noise. These characteristics have been fully utilized in the present nanoammeter. This operational amplifier is used in low level current to voltage configuration.
It is used to measure current from photomultiplier tubes, photometer etc.
It is also used for measuring leakage currents in solid-state devices.
