Description
Noise damper accessory for N 920 G and N 938.50 KT.18 is a dedicated outlet fitting that reduces acoustic emission on the pressure side of laboratory diaphragm pumps. It features an external G1/8 thread for direct screwing into the pump head, allowing straightforward installation on the exhaust path. Once fitted, the damper attenuates noise generated at the pump outlet, supporting quieter continuous operation in laboratory environments. The accessory is intended specifically for the N 920 G and N 938.50 KT.18 pump models and integrates into existing setups without changing core pump function. Supplied as a single piece from manufacturer KNF, it forms part of the accessories and spare-parts range for laboratory equipment. Laboratories that run these pumps for extended periods can use the damper to lower sound levels at the outlet while retaining full compatibility with the designated heads. The standardised G1/8 external thread ensures a secure mechanical connection and simple replacement when service is required. This compact noise-reduction component helps maintain a more comfortable working atmosphere around vacuum and transfer systems based on the listed KNF models.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Silencer Accessories for N 920 G and N, 938.50 KT.18
What is this article?
Silencer Accessories for N 920 G and N, 938.50 KT.18 is the article on this page. Luminix Health distributes KNF for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
