Made by TESA, the leader in Swiss precision measuring instruments. IP67 dust and liquid resistant coolant proof calipers with or without SPC (RS-232) output. This means they're totally protected from dust penetration and they still function correctly after having been subjected to low pressure water jets from all directions for three minutes. TESA Twin-Cal is identical to Brown & Sharpe Twin-Cal. The Brown & Sharpe name is used for marketing purposes in the USA while TESA covers the rest of the globe. - All digital models feature thumb wheel for easy sliding control
- Depth rod is availabe in round or square versions for the 6-inch model
- Wireless data output on Twin-Cal models (optional cables and software required)
- IP67 protected from dust and liquids (waterproof).
- Resolution is .0005" (0,01 mm) and accuracy is as follows
- 20 µm (approximately .0008") for the first 4 inches
- 30 µm (approximately .0012") from 4 to 12 inches
- Repeatability: 10 µm (approximately .0004")
- Large digital display for easy viewing.
- Switches easily between inch and metric.
- Calipers revert to idle mode after 10 minutes and full automatic shut-off after 2 hours.
- Battery (type CR 2032) life 1-1/2 years.
- The jaws are of high quality hardened steel giving them a long useful life.
- Instrument comes with an ID number, suitable for ISO requirements.
- Case and inspection report included
- Storage case
Appetite spoiler: The new Twin-Cal calipers do not have a country of manufacture stamped on them. This can mean only one thing: the majority of components and assembly are Chinese. Are you suddently turned off as we would be? The one consolation can only be that ALL currently manufactured digital and dial calipers are made in China to one degree or another. No manufacturer has come forward to claim otherwise. We'd love to be proven wrong on this. Some details on the TESA calipers
You can take depth measurements with the .060" diameter round rod which protrudes from the rear end of the calipers. You would easily be able to measure the depth of small holes, for example. Or, you can order the same model with the standard flat depth rod. What's really cool is that you can turn this into a wireless SPC caliper. An optional transmitter very simply replaces the large battery cover. Or, if you still have a fetish for electrical wires, you can run a cable from the battery cover to your PC's USB port. Okay, these add-ons cost money. For one thing, you will also have to buy TESA software (Stat Express or Data Direct) in order for all this to work. Suddenly your basic, simple digital caliper is an investment. But it's nice to have options. Like those digital cameras with a thousand and one settings. It's nice to know they're there but let me just point and shoot. (For the record: both Mahr and Mitutoyo make wireless calipers that do not require software if all you want to do is input raw numbers onto a spreadsheet.) Are you new to IP67? It's a somewhat cryptic way to tell you that this caliper, and other IP67 gages, will be able to withstand a considerable amount of moisture in the form of water spray, mist and dust without going haywire. You should look for this if you work in such an environment. It does not mean that you will be able to take it scuba diving, though. |
