Description
The Snap-on TESI30L Torqometer on this page is the plain signal model, listed by Lost in HCM with no certificate in its name. For the documented version, go to the TESI30LC with Calibration Certificate. Both share one 3/8 inch dial with a light that flashes at the target.
Signal model, plain code
In Snap-on’s CAT1500i, the TESI30L sits in the signal column of the Newton Meter Reading/Standard 2% Accuracy table. That table’s note says chart wrenches exclude a certificate of calibration. To get one, you add C to the stock number. So the TESI30L and TESI30LC differ by one document only.
Why development labs often skip the certificate
Engineering and test labs in electronics and automotive plants often own a torque analyzer. Their staff check each new tool against it, so they create their own record on day one. Also, prototype benches seldom fall under a customer audit. For these teams, the TESI30L gives the same dial and light without the extra document.
When the TESI30LC still makes sense
A pilot line that ships parts to a customer may need a record before first use. Likewise, a lab without its own analyzer would have to book an outside check. In those cases, the certified code saves a step.
What the Snap-on TESI30L Torqometer row shows
- Square drive size: 3/8 in.
- Range: 30 N·m, read in 1 N·m steps.
- Body: 9-29/32 in long, 2-11/16 in wide, 1-1/4 in head depth.
- Case: PB9.
Snap-on’s UK brochure rates its Standard 2% Torqometer wrenches within ±2% of reading from 20% of full scale. So readings from 6 N·m to 30 N·m sit inside that band.
Signal light work with the Snap-on TESI30L Torqometer
Pull slowly and evenly toward your target. When the bolt reaches the targeted torque, the built-in light on the TESI30L flashes. At that point, stop and read the needle for your log. This helps when the dial faces away, or when an operator must watch the part rather than the scale. Snap-on also warns never to exceed rated torque or break fasteners loose with the wrench.
Sourcing a TESI30L for your lab
Lost in HCM supplies the Snap-on TESI30L Torqometer and prepares every quote. Specify the plain code, so you receive the version without a certificate. Then request a quote from Lost in HCM, browse our torque wrenches, or contact SMK Vietnam with questions. Snap-on’s own site, snapon.com, also shows the wider range.
Lab bench questions on the TESI30L
Does the TESI30L flash a light rather than click?
Yes. As a signal model, it flashes a light at the targeted torque, while the needle still shows the value.
What sits below the TESI30L in the same table?
The TESI20L reads to 20 N·m in 0.5 N·m steps on the same 3/8 inch drive.
