Why local stock of counters and tachometers matters
When a production line, lab experiment or student project stalls because a frequency counter or tachometer is missing, downtime is costly. Communica keeps a practical range of handheld and panel tachometers, electronic counters, and RPM sensors on the shelf so technicians, makers and lecturers in South Africa can move from problem to solution without long lead times. Benefit from fast branch pickup, VAT invoices for procurement, and component-level support from staff who understand applied measurement needs.
What you’ll find in our inventory
- Handheld optical and contact tachometers for quick RPM checks.
- Panel-mounted digital counters (up/down, preset, batch) for small automation tasks.
- Frequency counters and timebase modules for lab and educational use.
- Accessory kits: pickup sensors, mounting clamps, and calibrated test targets.
We stock brands and modules that are widely compatible with microcontroller workflows and industrial retrofit applications. If you want to scout product ranges before visiting, see our Shop by Category page here and browse All Products here to compare form factors and mounting options.
Specification callouts to check before you buy
Choosing the right counter or tachometer is about matching measurement range and interface to the job. Key specs to verify:
- Measurement range (RPM, Hz) and minimum detectable pulse.
- Input type: optical, contact, magnetic, or logic-level pulse.
- Display update rate and resolution (e.g., 0.1 RPM vs 1 RPM).
- Supply voltage and power consumption for panel or embedded use.
- Mounting dimensions and bezel cutouts for panel meters.
