Overview
Kleinwächter GmbH is a German company based in Lörrach that manufactures high-precision measuring instruments for electrostatic discharge (ESD) measurement. According to its official website, the firm describes itself as a manufacturer of highly precise and globally leading measuring devices in the field of ESD measurement. Its product range includes electrostatic field meters, resistance and charge measurement systems, and related accessories used to verify compliance with ESD standards such as DIN EN 61340-4-1 and DIN EN 61340-4-5. The company's product line includes the EFM series of electrostatic field meters, with the EFM 025 being a recent development succeeding the EFM 022 and EFM 023. It also produces the TOM series of test instruments, including the TOM 600 and TOM 610, the latter featuring a touch screen. Kleinwächter has announced a successor model, the TOM 605, positioned as a cost-effective replacement for the TOM 600. The company also offers a Floor Analyzer for ESD testing, covering leakage resistance, system resistance, and personnel charging measurements. Kleinwächter serves customers who need to calibrate, repair, or verify ESD measurement equipment. The company emphasizes direct customer service, recommending that owners of its instruments send them directly to Kleinwächter for calibration or repair. It also provides ESD training through partners. The company operates in the worldwide market, with its products used in industries where electrostatic control is critical, such as electronics manufacturing, semiconductors, and cleanroom environments. As a privately held German company, Kleinwächter maintains a focused portfolio centered on ESD measurement technology. Its website highlights ongoing product development, including the EFM 025 and the forthcoming TOM 605, indicating continued investment in its core niche.
History
Kleinwächter GmbH is a German company located in Lörrach, Germany, as indicated by its Wikidata entry. The company has established itself as a manufacturer of high-precision measuring instruments for electrostatic discharge (ESD) measurement. Its official website states that it is a manufacturer of highly precise and globally leading measuring devices in the field of ESD measurement. The company's product history includes the development of the EFM series of electrostatic field meters. The EFM 022 and EFM 023 were earlier models, and the EFM 025 represents a further development, designed for the detection and measurement of electrostatic fields. The TOM series includes the TOM 600 and the more advanced TOM 610, which features a touch screen and applications unique to that device. Kleinwächter has also announced the forthcoming TOM 605 as a cost-effective successor to the TOM 600. Kleinwächter has faced distribution changes: its website includes a correction stating that, contrary to the representation on the website of a vendor that no longer distributes its devices, both the TOM 600 and TOM 610 can still be supplied without problems and comply with valid ESD standards. The company recommends that customers of that vendor send their devices directly to Kleinwächter for calibration or repair. The company also offers a Floor Analyzer for ESD testing, which facilitates leakage resistance, system resistance, and personnel charging measurements according to DIN EN 61340-4-1 and DIN EN 61340-4-5. Additionally, it provides ESD training through a partner. Kleinwächter continues to develop and market its products worldwide, maintaining a focus on ESD measurement technology.
