Product Code : SCL-MDE-12445
Indian Lab Suppliers offers the Pulse Rate Meter Trainer (Product ID: 12445) as part of its Medical Diagnostic Equipment range under Hospital Lab Equipment. This is a plethysmograph-based educational trainer that detects the arterial pulse and pulse-pressure waveform using an infrared LED/phototransistor sensor pair, letting students study pulse-wave characteristics and their relationship to blood pressure and flow.
Quick Answer
This trainer detects the arterial pulse pressure waveform – the vessel-wall displacement produced each time the heart contracts and ejects blood – using a photoplethysmographic (IR LED/phototransistor) sensor typically placed at the fingertip or another peripheral point. It provides an amplified pulse output with on-board variable gain control, separate test points after each functional block, an LCD display, and roughly 4% accuracy, letting students record the pulse waveform, estimate pulse-wave velocity (which the source material notes as travelling at roughly 5 to 15 metres/second depending on arterial wall size and rigidity), and compare it against an ECG signal.

Frequently Asked Questions
What does this trainer measure?
It detects the arterial pulse pressure waveform – the vessel-wall displacement caused by each heartbeat – using an infrared LED/phototransistor sensor pair, typically placed at the fingertip.
What sensor is used and how is it connected?
A 3mm IR LED (940nm wavelength, blue lens) paired with a 3mm silicon IR phototransistor (black lens), connected via a 2-core shielded cable (approx. 1.1 metres) with a 3.5mm stereo plug.
Can I compare the pulse signal with an ECG?
Yes, the supplied study material describes comparing the recorded pulse waveform with a simultaneous ECG signal, and discusses pulse-wave velocity in that context.
What is the accuracy of the reading?
Approximately 4%, with selectable accuracy levels on the LCD display.
Can I observe the raw waveform at each stage?
Yes, separate test points are provided to observe the waveform after each functional block.
