Datalogger Manufacturer,Supplier and Exporter in India

Product Code : EL-TWL-9190
Jlab Export is a leading Datalogger Manufacturer,and suppliers in India

This datalogger records readings from lab experiments, either on its own or connected to a PC. It has built-in sensors for voltage, current, temperature, luminosity, magnetic field and absolute gas pressure, and four more analog inputs take external sensors. Readings show on a graphic display, runs are set with a five-key joystick, and data is stored in 2 MB of memory.

Experiments Logged with the Datalogger

A cooling curve is a common first run. Students log the temperature of hot water as it cools in the Apparatus for Newton’s Cooling Law. The graph builds on screen, with no thermometer to read by hand. With the voltage and current sensors in a lamp or resistor circuit, a Rheostat 30 Ohm varies the current while the logger plots voltage against current.

The luminosity sensor, moved in steps along a Meter Scale 100 cm from a small lamp, shows how light falls off with distance. The magnetic field sensor traces the field along the axis of one of the Solenoids with Cores, with and without its core. The analog outputs and signal generator can drive a capacitor and resistor circuit, and fast sampling captures the charging and discharging curves.

Frequently Asked Questions

Can the datalogger be used without a computer?
Yes. In stand-alone mode the quantities appear on the 128 x 64 pixel graphic display and the joystick sets each run. Readings are held in the 2 MB internal memory, and the unit can later be connected to a PC over USB to process them.

What sampling rate should I choose?
Match it to how fast the quantity changes. The maximum of 1 MHz per channel suits electrical signals such as capacitor charging. A cooling curve needs only one reading every few seconds, and a faster rate just fills the memory with almost identical values.

What does 12-bit resolution mean?
The converter splits each input range into 4,096 steps. The smallest change the logger can show is the range divided by that number, so a sensor with a narrower range gives finer steps.

How is the datalogger powered?
It takes power over USB when it is connected to a PC. For work away from a computer it can run from an external USB power supply.

Can more sensors be added?
Yes. Besides the built-in sensors there are four analog inputs for external sensors and three digital inputs. Digital inputs suit on and off signals, for example from timing gates.
