Comprehensive Tester: One Unit, Multiple Measurements
A comprehensive tester doesn’t have to come with a steep learning curve. At Kingmach, we’ve spent years simplifying multi-parameter monitoring for field engineers. The idea is straightforward: put strain, pressure, displacement, and other readings into a single portable unit, so you’re not lugging around a collection of single-function devices. We developed our testers after listening to clients who needed faster setup and fewer compatibility issues on job sites. They wanted something that could talk to different sensor types without adapters or workarounds. The result is a line of instruments built to cut down on manual switching and data syncing. Whether you’re checking bridge health or tracking ground movement, this approach keeps things practical — real-time readings, easy logging, and less guesswork.
Technical Detail
When you deal with geotechnical or structural monitoring, the fewer boxes you need to carry, the better. Kingmach’s comprehensive testers are designed to centralize measurements typically spread across multiple instruments. They handle inputs from vibrating wire sensors, potentiometers, thermistors, and other common geotechnical sensors, pulling data into one display. You can view readings in engineering units on-site, without back-and-forth conversions. The internal logging stores session data, and a USB or wireless link lets you transfer files to a PC for further analysis. We build these testers with field conditions in mind: the housing is IP65-rated against dust and light rain, and the screen remains readable in direct sun. Power comes from rechargeable batteries that last a full workday under normal use. Because every project has its quirks, we offer customization on sensor channel count, measurement range, and output formats. Our technical team works with you during commissioning to match the unit to your specific sensor fleet. After deployment, our support network — spanning distributors in over 30 countries — provides calibration services and troubleshooting so downtime stays minimal.

It works with most common geotechnical sensors: vibrating wire, 4-20 mA, potentiometer, thermistor, and strain gauge types. If you use something less typical, we can usually add a custom input channel — just send us the sensor specs.
You have two options. Connect via USB to a laptop and pull CSV files directly, or use the built-in wireless module to sync with a cloud platform if that’s part of your setup. No proprietary software is needed for basic file transfer.
Yes. The standard configuration covers 8 channels, but we can go higher on request. Let us know your monitoring layout and sensor count, and we’ll quote a configuration that fits.
We offer remote diagnostics first — often a screen share resolves setup issues. For hardware problems, we handle repairs at our service center or through a local partner. Annual calibration is recommended to keep accuracy within spec.
The battery is internal but accessible through a panel on the back. You can swap it yourself with a standard replacement pack we sell, no special tools needed.
