The coolants in electric vehicles and fuel cell systems often contain special inhibitors and additives that prevent corrosion and ensure optimal dielectric properties. An increase in the coolant's electrical conductivity is a direct indication that:
Depletion of Inhibitors: The protective agents have been depleted, which increases the risk of corrosion of metal components (aluminum, copper).
Contamination: Foreign substances (e.g., water, oil, or other electrolytes) have entered the system.
Impaired Heat Transfer: Fluid with inadequate conductivity reduces heat transfer efficiency, which can lead to overheating in batteries or the fuel cell, drastically reducing their service life and performance.
Regular conductivity testing with this instrument enables proactive maintenance, preventing expensive and time-consuming repairs.
This instrument is the ideal choice:
Brand Service Centers: For maintenance according to factory specifications.
Independent Workshops: For EV and FCEV repairs requiring special expertise.
Battery and Fuel Cell Manufacturers: For quality control processes.
Fleet Managers: For maintenance of a large number of electric vehicles.
For comprehensive servicing, accessory tools found in the following categories are also available:
Cooling System Testers: Pressure testing kits and vacuum filling equipment.
E-Mobility Diagnostics: Leak testing tools for HV components and thermal management filling/testing equipment.
General Workshop Tools: Digital pressure gauges, hydraulic test kits (analog and digital), as well as general electrical test lamps and multimeters.
Coolant Tester Refractometers: For checking the quality of battery acid, coolant, windscreen washer fluid, and AdBlue.
This conductivity meter is an essential tool for any technician who wants to guarantee the reliability and efficiency of the cooling systems in electric and fuel cell vehicles. Precise measurement ensures the long-term, optimal operation of the vehicles.
