Easy to read. Easy to install. Somewhat easy to program. Battery life is a few weeks if you don't disable it after use. Just press the two buttons at the same time and it will shut down. Touch one again and it will turn back on instantly. A 6pk of batteries is cheap and will last years. I use it to keep and eye on engine temp too... but it is mainly used from RPMs on my little 2004 Mercury 5HP 2-stroke outboard engine. I was able to adjust proper idle rpms for a good running engine @ idle/under load. I was also able to realize that my max RPMs were too high with the stock prop... so, I got a new prop, and can now go faster. One shot needed/no guessing required. This made this a very valuable modification. Not having to pull out my phone to check the time when on the water, may save me a phone too. Review: Perfect - Got it for my phatmoto motirized bicycle with a 80cc engine. Its works perfectly. Rpms and temp read very accurately. Not sure why one of the reviews say it doesnt have a tachometer when that is the main function. One small issue is it would turn off on its own so i just have to manually shut it off which is easy.just press both buttons simultaneously for 2 seconds. ## Features - HOURS ---- Monitor the total run time(TOT) and single working hours(JOB) of gas engine, with ability to program previous hours(INT) for an replacement;Accomplish maintenance at recommend intervals to determine the due time(SVC);TOT & JOB hours range:0-999,99 hours;SVC timer range:5-1000 hours - RPM ----- Display the real-time RPM readout by vairous engine firing patterns setting to adjust engine idle speed; Alert channel for revolution exceed reminder;Viewable highest revolution since the engine started; RPM measurement range: 0-25000RPM, Alert range: 100-25000RPM - TEMP ---- Keep eyes on engine current and maximum temperature at all the times by probe senor(The induction probe cannot be bent to avoid breakage); Remind the temperature exceed for engine maintenance; Easy to switch between Celsius and Fahrenheit;Temp measurement & alert range: -20°C~+300°C(-4°F~+572°F) - BACKLIGHTS ---- Default green backlight will help to use it at night or dim place, you can set the backlight mode by always-on, OFF and automatical mode(OFF default, button to wake up) as request;Red backlight will remind the engine RPM or TEMP exceed - OTHERS ---- Easy to mount it on proper position by stick-on, screw-on and extra bracket(not include), one-wire connection with spark plug to pick up working signal (At least 5-8 circles tight winding; Total Length 68.8inches, workable if shorten or extend) to work right away;Favorable water and shock resistence; Battery capacity will be kept in good condition with insulation sheet during transport, it is repalceable;LCD shutdown also can extend the lifetime in vacant time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B092CDSQ33 | | Best Sellers Rank | #35,801 in Automotive ( See Top 100 in Automotive ) #13 in Automotive Tachometers | | Brand Name | Runleader | | Customer Reviews | 4.0 4.0 out of 5 stars (1,180) | | Item Dimensions | 1.46 inches | | Item Weight | 60 Grams | | Manufacturer | Ningbo Jiangbei Run Leader Electronics Co., Ltd | | Material Type | Plastic | | UPC | 723093900728 | ## Product Details - **Brand:** Runleader - **Item Weight:** 60 Grams - **Item dimensions L x W x H:** 1.46 inches - **Material:** Plastic - **Thread Type:** Spark Plug Wire Wrap (One-wire) ## Images ![RL-HM035A-TS002 Digital LCD Hours Tachometer,Engine Temperature Gauge - Image 1](https://m.media-amazon.com/images/I/61DDCc33beL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How do you connect it to read engine temperature?** A: Remove the spark plug.

It was enticing because it was less expensive than a trailtech one and also had the tachometer feature. I disliked the sparkplug head temp sensor since it was not bent 90degrees. I had to bend it myself because it would not fit with the aircool fins on my bike. The display just went out on me where it was missing specific lines so the letters and numbers were very hard to read. It refused to auto off so it wasted battery unless you manually turned it off. I tapped on the display gently to try and get the letters/numbers back and it just immediately cracked, very fragile. I will not buy again and will now pay even more to get a trailtech ## Frequently Bought Together - Runleader Digital Tach Hour Meter,Engine Temperature Gauge,Alert RPM & Temp,Backlights Display for Lawn Tractor Compressor Generator Snowmobile Marine Jet Ski Pit Bike - HIAORS 50 inch Throttle Cable for CT200U Mini Baja MB165 196cc 5.5hp MB200 200cc 6.5hp Pit Bike Heat Warrior MOTOVOX MBX10 MBX11 Parts - YAMAKATO 16pcs Carburetor Jet Kit Main Jets for Mikuni VM22 VM24 VM26 125cc 150cc 200cc 250cc for Mini Bike Dirt Bike Pit Bike ATV 88 90 95 98 100 105 110 115 120 125 130 135 140 145 150 155 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/318290599-rl-hm035a-ts002-digital-lcd-hours-tachometer-engine-temperature-gauge](https://www.desertcart.pl/products/318290599-rl-hm035a-ts002-digital-lcd-hours-tachometer-engine-temperature-gauge) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-11*
