DTI Tiny Tach TT2B digital tachometer and hour meter — compact sealed housing, ignition-pulse RPM and cumulative run-time

The DTI Tiny Tach TT2B is a compact digital tachometer and hour meter designed to track engine RPM and cumulative run time on small gas spark engines.

The Tiny Tach TT2B combines a precise tachometer with an integrated hour counter in a weather-resistant housing, giving you clear RPM readings and a reliable record of total operating hours. It is engineered for compact engines commonly found in lawn equipment, generators, pressure washers, and other light machinery. Before ordering, confirm compatibility with your engine by checking model, serial, type codes, and year; our product team can assist if you provide those details.

How does the TT2B measure engine speed and runtime?

The TT2B detects ignition pulses to calculate RPM and uses that same input to accumulate total operating hours automatically. Its digital readout shows current engine revolutions per minute instantly while the internal counter logs total run time even across power cycles. Installation requires a connection to the engine ignition or a suitable pickup point following the provided wiring schematic.

• Tachometer: senses ignition pulses to display RPM in real time
• Hour meter: stores cumulative run time across shutdowns
• Digital display: clear numeric readout for RPM and hours
• Wiring: connects to ignition/pulse source per instructions

What are the physical and durability features of the unit?

The Tiny Tach TT2B is built for rugged, outdoor service with a compact footprint that fits tight engine bays. Its sealed case helps resist moisture and debris, while mounting options allow secure placement on frames or control panels. The display remains legible in varied lighting and the electronics are designed for typical vibration levels encountered on small engines.

• Compact, low-profile housing saves space
• Sealed construction offers resistance to dust and light moisture
• Mounting points for secure attachment to engine or frame
• Readable digital display suitable for service environments

How easy is installation and operation for non-professionals?

Installation is straightforward for anyone comfortable with basic wiring and engine terminals: locate the ignition pulse lead, follow polarity instructions, and attach ground. The unit powers from the engine circuit and requires minimal adjustment after mounting. Operation is largely automatic—RPM updates continuously and the hour meter logs running time without manual resetting.

• Simple wiring to ignition/pulse and ground
• No regular calibration needed after initial setup
• Automatic hour accumulation—no user input required
• Clear readout minimizes need for troubleshooting

What should I check for compatibility before buying?

Confirm that your engine uses a compatible ignition pulse source and that you can access the pickup point for wiring. Check engine make, model, type codes, and year against the product specifications to ensure fitment. If you're unsure, supply those details to our support team and we'll verify whether the Tiny Tach TT2B matches your equipment.

• Verify ignition/pulse availability on your engine
• Compare model and type numbers with product specs
• Provide horsepower, serial, and year information if available
• Contact product specialists for fitment confirmation

Who is this for: The DTI Tiny Tach TT2B is ideal for owners and technicians of compact gas-powered equipment who need an accurate RPM readout and a dependable way to track total operating hours. It's useful for scheduled maintenance planning on lawn tractors, generators, pressure washers, portable pumps, and similar small-engine machines. If you maintain fleet tools or manage servicing intervals, this compact meter delivers essential engine data in a small, durable package.
