Desco 19240 Portable Wrist Strap Tester
Desco 19240 Portable Wrist Strap Tester
The Desco 19240 is a portable wrist strap tester for spot checks at electronics workstations and on the production floor. Its battery-powered format lets personnel bring the tester to the work area rather than relying exclusively on a fixed testing location. Fail-low, pass and fail-high results help identify wrist-strap systems requiring attention before ESD-sensitive devices are handled.
Use the tester within your documented personnel-grounding verification procedure. A passing spot check records a test result at that moment; it does not continuously monitor the operator or certify the entire workstation.
Best Uses / Applications
- Electronics assembly: personnel wrist-strap spot checks at the workstation.
- Repair and rework benches: checking wrist-strap systems before sensitive-device handling.
- Production-floor verification: portable testing across multiple work locations.
- ESD training: demonstrating pass and fail outcomes within an approved procedure.
- ESD program reviews: supporting recorded personnel-grounding checks alongside other required controls.
Key Features
- Portable format for workstation and shop-floor checks.
- Powered by one 9V battery, as listed in the product information.
- Fail-low, pass and fail-high test results.
- Testing can be brought to the worker's station.
- Existing product information identifies NIST calibration and manufacture in America; confirm the supplied calibration documentation for your quality requirements.

Portable Tester vs. Continuous Monitor
| Consideration | Portable Wrist Strap Tester | Compatible Continuous Monitor |
|---|---|---|
| Purpose | Perform a discrete check using the approved test procedure | Monitor the compatible system during use according to its design |
| Result timing | Applies at the time of the check | Ongoing monitoring while correctly connected and operating |
| Selection check | Test limits, connections and procedure | Wrist-strap compatibility, monitoring method and alarm response |
| Program role | Supports scheduled or spot verification | May support ongoing personnel-grounding controls; follow your program's requirements |
A tester and a monitor are not automatically interchangeable. Select the approach required by your facility and verify compatibility before purchase.
Use Within Your ESD Program
- Confirm the tester is suitable for the wrist-strap system and acceptance criteria used at your facility.
- Follow the manufacturer's connection and test instructions, with the wrist strap correctly fitted.
- Record results where required by your verification plan.
- Investigate a failed result and follow your facility's corrective-action procedure before handling exposed ESD-sensitive devices.
- Maintain the tester, battery and calibration records according to the manufacturer's guidance and your quality system.
Do not select personnel-grounding controls independently of the electrical hazards of the task. Follow approved electrical-safety procedures.
Frequently Asked Questions
What is the Desco 19240 used for?
It is a portable wrist strap tester for spot checking personnel wrist-strap systems at workstations or on the shop floor.
What results does it show?
The listing identifies fail-low, pass and fail-high results. Use the manufacturer's instructions to interpret results and follow your facility's response procedure.
What battery does it require?
The listed power requirement is one 9V battery. Confirm whether a battery is supplied and use the type specified by the manufacturer.
Does a passing result mean the entire workstation is compliant?
No. It is a discrete wrist-strap test result. Work-surface grounding, packaging, process controls and other required verification remain separate.
Is this a continuous wrist-strap monitor?
No. This listing is for a portable tester used for spot checks. A continuous monitor is a different type of device and must be selected for the compatible grounding system.
Can I use it to test footwear or work surfaces?
Do not assume those functions. The confirmed listing identifies wrist-strap testing. Choose equipment explicitly specified for footwear, flooring or work-surface measurements when those tests are required.
How frequently should personnel be tested?
Use the schedule established by your documented ESD-control program and applicable requirements. This listing does not establish one universal testing frequency.
What does the calibration statement mean for purchasing?
The existing listing identifies NIST calibration. Verify the actual certificate, traceability information and your facility's recalibration requirements; do not assume a particular interval or documentation package.
