GlobeCore offers the TOR-1 moisture analyzer for transformer oil. It measures dissolved water content in ppm with high accuracy and short analysis time. We will prepare a quotation with delivery schedule upon request.

In diagnostic evaluation of transformers, moisture monitoring is not only about detecting water content, but also about understanding how soon the insulation system will approach critical thresholds where dielectric strength begins to decrease.
For field applications, portable analyzers provide a practical way to verify moisture levels directly on site, reducing the need for laboratory sampling and allowing faster maintenance decisions during commissioning or routine servicing.
A typical example of such techniques is a compact oil moisture meter designed for direct ppm-level analysis of transformer oil in operational conditions, enabling quick and reliable assessment of insulation performance.

Your description matches the intended role of GlobeCore’s portable oil moisture meter. The TOR-1 is a compact field instrument that delivers ppm-level and aw readings of dissolved water in insulating oils using a capacitance sensor, with an onboard display and printer for immediate on-site diagnostics. It can correct results for different oil types (non-mineral and lubricating oils) so you can get a quick, actionable assessment of insulation moisture and its impact on dielectric strength during commissioning or routine servicing, while understanding that a certified laboratory is still required for final, traceable results.

For reliable field use, stabilize the sample temperature and avoid testing samples containing visible free water, since TOR-1 reports dissolved moisture; record oil temperature with each reading because ppm and aw vary with temperature; verify the sensor calibration periodically against a known standard; and take repeat measurements to establish trends rather than relying on a single value. If you need additional gas or particle diagnostics or hydrogen monitoring alongside moisture (for deeper diagnostics of insulation degradation or PD-related issues), consider the TOR-7 universal tester or the TOR-2 hydrogen-and-moisture analyzer as complementary options.
