Description
The Snap-on TESI20L Torqometer sold here is the plain light signal code, with no certificate in its listing name. For the certified twin, go to the TESI20LC with calibration certificate. Snap-on builds both from one stock number, and the C adds the document.

One wrench, two order codes
In CAT1500i, the Newton Meter table lists the TESI20L as a signal model. First, its note says the wrenches shown ship without a certificate of calibration. It also says a C at the end of the stock number orders one. So the Snap-on TESI20L Torqometer costs less, while the TESI20LC saves a first lab visit.
How the light helps on a busy floor
Snap-on gives its signal models a built-in light that flashes when you reach the targeted torque. So that cue suits switchgear and telecom cabinet work, where noise and poor light make a dial hard to watch. For example, a TESI20L operator can set the target, pull, and stop at the flash. Meanwhile, the needle still shows the torque achieved.
Picking between the TESI20L and the TESI20LC
- Go plain with the TESI20L when your tool room verifies each new wrench on its own bench.
- The plain code also suits a spare tool that you cross-check against a master wrench.
- Choose the TESI20LC when a customer audit needs a record from the day of delivery.
- In addition, take that code if incoming inspection rejects gauges with no documents.
Snap-on TESI20L Torqometer at a glance
| Item | CAT1500i value |
|---|---|
| Drive | 3/8 in square |
| Scale | 20 N·m, 0.5 N·m steps |
| Length / width | 9-29/32 in / 2-11/16 in |
| Head depth (no drive) | 1-1/4 in |
| Case | PB9 |
| Grade | Newton Meter Reading, Standard 2% Accuracy |
In addition, Snap-on’s UK brochure states the 2% band from 20% of full scale to full scale, both ways. On the TESI20L, that band starts at 4 N·m.
Looking after the TESI20L
Store it in the PB9 case, because a drop can upset any dial mechanism. Also keep within its rated torque, and never break screws loose with it. Then book periodic recalibration, as Snap-on advises for every Torqometer.

Questions about the TESI20L
Is there a version without the light?
Yes. Beside the TESI20L, the same row lists the TESI20 Basic and the TESI20FU Follow-up models.
Does the TESI20L read in ft-lb?
No. This table covers newton meter reading only, so the dial shows N·m.
Can our lab issue the record instead?
Yes. Your lab or an outside lab can test the TESI20L and write its own report.
