The engineers who certify your protection now stand behind it — every second.
Anyone can sell you a sensor and a dashboard. Wattson & Ohms gives you what a monitoring vendor can’t: accredited engineers who certify your earthing, lightning, surge and cathodic protection to SANS 10313 and IEC 62305, watch it continuously with our own instrument, GeoGuard, and remediate it when it drifts. The dashboard is how you see it working — the accountability behind it is what you’re actually buying.
Your protection is tested and certified periodically. In between, you’re trusting that nothing has changed. But things change — electrodes corrode, soil dries out, a grader clips a down conductor, a surge device silently exhausts its life, and copper runs get stolen. A certificate can’t warn you. Continuous monitoring can.
Four protection layers, one dashboard.
Earth resistance and impedance, continuity of down conductors and earth mats, and immediate theft-and-breakage alerts the moment continuity is lost. Measured by GeoGuard, our own instrument, applying the fall-of-potential and clamp-on methods of the international reference standard (IEEE 81) — continuously, not once a year.
Live device status, MOV degradation and end-of-life signalling — so a spent surge device is flagged the day it needs replacing, not discovered after it's failed to protect your equipment.
Strike counting, air-termination and down-conductor integrity, integrated with lightning-warning data so strikes near your site are logged automatically against your protection performance.
Pipe-to-soil potential, rectifier output current and voltage, anode consumption and reference-electrode readings — continuous condition monitoring for pipelines, tanks and buried structures.
Measure. Connect. See. Act. Certify.
GeoGuard, our own instrument, is fitted to your earthing, surge, lightning and cathodic protection, taking real measurements by the international reference methods (IEEE 81) — continuously, and re-anchored to a full fall-of-potential test on schedule.
A rugged on-site gateway securely streams that data to the cloud over LTE or your network — no reliance on someone remembering to take a reading.
Everything lands on your secure dashboard: live values, historical trends and site-by-site status, accessible from any device.
Configurable alerts reach your team by SMS, email or app the instant a value drifts out of spec or a conductor is lost — so we fix problems while they're still small.
On a schedule the data lets us stretch, our own engineers attend site for the physical inspection no sensor can do — checking corrosion, bonding and connections — and issue the signed certificate. The monitoring makes the visit shorter and better targeted; it doesn't pretend to replace it.
Anyone can stream the numbers. We can sign for them.
A general-purpose IoT provider can stream numbers off your site. What they can’t do is tell you whether those numbers mean your protection is compliant, sign the certificate that says so, or send a crew to put it right. That gap is the whole point.
Raw earth-resistance data means nothing without knowing what “good” looks like under SANS 10313 and IEC 62305. Our engineers do — it’s been our core business for years.
As an accredited protection-engineering firm, our monitoring feeds a compliance record you can put in front of an auditor, an inspector or an insurer. A dashboard vendor can’t sign for that.
Professional engineering accountability sits behind every reading. When something drifts out of spec, that’s our problem to solve — not just a red light on your screen.
Detecting a fault is half the job. Our own teams remediate — repair the earth run, replace the spent SPD, restore the stolen conductor — so the alert ends in a fixed system, not another work order for you to chase, and not handed to a subcontractor whose work we’d have to check.
Six ways monitoring pays for itself.
The moment an earthing conductor loses continuity, you get an alert — not a nasty surprise at the next audit or the next storm.
Catch degradation early and schedule remediation on your terms, instead of reacting to a fault that's already stopped production.
Instead of a certificate that's eleven months old, you hold continuous, timestamped data behind it — so when an auditor asks how you know the system is sound today, you show them, not tell them. The signed certificate is still issued by our engineers, as the standards require; monitoring strengthens the evidence, it doesn't replace the inspection.
Continuous, timestamped protection data strengthens your due-diligence record where lightning and earthing safety carry real liability.
Verified, continuous protection is a stronger position at renewal than a certificate that's eleven months old.
Trend analysis shows you what's drifting and when it'll need attention — before it fails.
Three ways to work with us.
Once our gateway is on site, we can bring generators, power meters, water and cold-storage onto the same dashboard through our monitoring partners. The earthing assurance stays ours end to end; wider site monitoring is a capability we add on top.
