How we scored them
Each meter is scored out of 10 on performance, build, value, safety and warranty, using only what the listing publishes. The weights are on our How We Pick page. None of these listings states a warranty term, so all score zero on warranty.
| Product | Woodlot Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| HFWHOK Hour Meter Tach | 9.7 | 32 | 21 | 22 | n/a | 0 |
| HTPREC Digital Tach | 9.6 | 30 | 20 | 21 | n/a | 0 |
| DDayuanwei RPM Meter | 9.6 | 29 | 20 | 21 | n/a | 0 |
| AUGREX Inductive Tach | 9.5 | 29 | 19 | 20 | n/a | 0 |
| Stihl EDT 9 Tachometer | 9.5 | 26 | 20 | 18 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
How to choose the best chainsaw tachometer
RPM range and accuracy
Three of these meters state 100 to 30000 RPM at 1 percent accuracy; the HFWHOK states 0 to 18,000 RPM at plus or minus 10 RPM; the Stihl states no range at all. Match the stated range to the engines you tune, and read the accuracy figure as the maker’s claim, not a measured fact. Note the gap in the field: only two of the five listings state any accuracy figure at all, and the Stihl states neither range nor accuracy.
Hour tracking and alarms
If the meter lives on the saw, hour tracking pays off. The HFWHOK keeps TOT, JOB and service-countdown hours plus a MAX RPM readout and a programmable RPM alarm that turns the backlight red past the set value. The HTPREC and DDayuanwei offer minute timers to 99999 minutes instead. If you service by the calendar rather than by hours, the minute timer still tells you how long the engine has actually run since the last reset.
Sensing method
All five read inductively from the spark plug wire: wireless at 3 to 5 cm on three of them, a clip on the wire on several, and a 60 cm clamping cable on the Stihl. The HTPREC adds a copper pickup wire for a second wired option. None needs an external power connection per the listings. Wireless sensing at 3 to 5 cm is the least fiddly for a quick check; a clipped wire stays put for a longer tuning session. Keep the sensor clear of hot exhaust parts while it reads.
Wear eye protection and gloves for cutting, splitting and handling, follow every tool's manual, install stoves to code, and have the chimney inspected and cleaned every year. See EPA Burn Wise and NFPA heating safety. Read our Safety Disclaimer.
Around the Woodpile
- Clip or hold the sensor on the plug wire only with the engine at a steady idle for mode checks, per the HTPREC listing’s method.
- The HTPREC listing warns that mode numbers are not stroke counts: try the modes at idle and keep the one whose reading matches the engine.
- Replace the HFWHOK battery when its low-battery indicator shows; the listing says recorded data survives the swap.
- A tachometer tunes the saw; it does not replace chaps, a helmet with face screen and hearing protection, gloves and boots.
- Write the reading down: an idle RPM logged each season shows drift long before the saw tells you by ear.
Frequently Asked Questions
What does a chainsaw tachometer measure?
Engine speed in RPM, read inductively from the spark plug wire. These meters state ranges from 0 to 18,000 up to 100 to 30000 RPM, for 2-stroke and 4-stroke gasoline engines. The number on the screen is the engine’s actual speed, not a setting, which is what makes it useful for checking idle and max RPM against the saw maker’s figures.
How do you attach a tachometer to a chainsaw?
These five attach without wiring into the engine: clip the pickup to the spark plug wire, wrap the harness around the plug wire sleeve, or hold the meter 3 to 5 cm from the wire. The Stihl uses a 60 cm clamping cable on the ignition cable or plug boot.
Do I need an hour meter on my saw?
It helps schedule maintenance by actual run time. The HFWHOK keeps TOT, JOB and service-countdown hours with a programmable RPM alarm; the HTPREC and DDayuanwei keep minute timers to 99999 minutes instead.
What is the RPM alarm for?
The HFWHOK’s programmable RPM alarm turns the backlight red when the engine passes the set RPM, so you see over-revving at a glance. None of the other four listings states an alarm.
Can a tachometer work on other small engines?
The listings name chainsaws, lawn mowers, generators, motorcycles, ATVs, snowmobiles and boats among the uses. All five read 2-stroke and 4-stroke gasoline engines; the HTPREC and DDayuanwei state 1 to 8 cylinders.
Will a tachometer work on a 4-stroke engine?
These five all state 2-stroke and 4-stroke compatibility. The HTPREC and DDayuanwei name 1 to 8 cylinders, the AUGREX names two-stroke single-cylinder and four-stroke twin-cylinder engines, and the HTPREC listing warns to pick the firing mode by the idle reading, not by the stroke count.
