Two Channel Recorder
Two Channel Recorder (Product Code: SLE/EA/04) is a two-pen chart recorder used to draw a permanent paper trace of electrical signals during laboratory experiments, and it is listed to work with the Flight Demonstration Wind Tunnel. Engineering lab staff use it for its 200 mm chart, a 1 mV to 50 V input range, 16 chart speeds and long-life fibre-tip pens that stand up to student use. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Two Channel Recorder Used For?
A chart recorder moves paper at a set speed while a pen follows the input voltage, so a changing quantity is drawn as a line against time. With two pens, students can plot two signals on one chart and see directly how one responds to the other, which is ideal for transient experiments such as the motion demonstrations on a wind tunnel model. The paper record can be annotated, measured with a ruler and stapled into the lab report.
Pick a fast mm/sec speed to spread out quick events and a slow mm/min speed for long runs. Set each channel's range so the trace uses most of the 200 mm width without hitting the edge. The electric pen-lift on each channel lets you raise a pen between runs to avoid stray marks, and capping the pens after the session keeps the fibre tips from drying out.
What to Specify When Ordering
- 1-channel or 2-channel version.
- The signals you will record, so they can be checked against the 1 mV – 50 V range.
- Whether it will be used with the Flight Demonstration Wind Tunnel or with other apparatus.
- Spare pens and chart paper for the term; ask us what can be quoted.
Supplier
Jain Scientific Equipments Private Limited, under its ScienceLab brand, supplies the Two Channel Recorder to aeronautical and mechanical engineering departments, polytechnics, dealers and importers in India and international markets. The recorder can be quoted together with the wind tunnel and other aerodynamics equipment in one order.

Related Aerodynamics Lab Equipment
These items are used with the recorder or as alternative ways to capture signals:
- Flight Demonstration Wind Tunnel — the apparatus this recorder is listed to work with.
- Subsonic Wind Tunnel — lift, drag and pressure experiments in a larger tunnel.
- Oscilloscope Dual Trace — for viewing fast two-channel signals on screen instead of paper.
- Advanced Digital Multimeter — checks signal levels before setting the recorder range.

Frequently Asked Questions
What is the input range of the Two Channel Recorder?
The Two Channel Recorder covers an input range of 1 mV to 50 V, which lets it trace both small sensor signals and larger voltages. Choose the range on each channel so the trace fills the 200 mm chart without running off the edge.
How many chart speeds does the Two Channel Recorder have?
The Two Channel Recorder offers 16 different chart speeds from 0.1 to 20, selectable in mm/sec or mm/min. Fast speeds spread out quick transients, while slow speeds suit long, gradual runs.
Is the Two Channel Recorder available in a single-channel version?
Yes. The Two Channel Recorder is listed in 1-channel and 2-channel versions. Each channel has its own electric pen-lift, so on the two-channel model either pen can be raised independently between runs.
Which apparatus does the Two Channel Recorder work with?
The Two Channel Recorder is listed to work with the Flight Demonstration Wind Tunnel. It can also record other voltage signals within its 1 mV to 50 V range; confirm your signal source with us through the contact page.
Who supplies the Two Channel Recorder?
The Two Channel Recorder is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to engineering institutions, dealers and importers in India and international markets, and can be ordered together with the wind tunnel it serves.
Is a calibration certificate available for the Two Channel Recorder?
A calibration certificate for the Two Channel Recorder is not listed as standard. If your laboratory requires one, please discuss it with us through the contact page before you place the order.
