About This Brand

Keysight + at Z & F Corporation Ltd

Keysight +

Unlike our legacy Agilent stock, this is current-catalogue Keysight Technologies equipment — the RF and microwave test business that split from Agilent in 2014 — spanning CXA spectrum analysers, N51xx-series RF signal generators, and E50xx-series vector network analysers up to 3 GHz.

We are not Keysight Technologies, and not an authorised Keysight Technologies distributor — we source and supply genuine Keysight Technologies stock through the open market and established distribution channels, with datasheets and certificates of conformity available on request. For legacy pre-2014 Agilent-branded equipment, see our Agilent brand page; for spectrum analysis specifically, see our Spectrum Analyser category.

Frequently Asked Questions

Is this the same company as Agilent?
Related by history, not by current ownership — Keysight Technologies was spun off from Agilent's test-and-measurement business in 2014 and now operates as its own company. This page covers Keysight-branded equipment specifically.

Electrical

7 products

Z & F Corporation Ltd supplies industrial electrical products worldwide — circuit protection, switching, contactors and enclosures for panel builders, MEP contractors and plant maintenance teams across the UK, the Gulf and South Asia. Every part we ship is genuine, sourced through established manufacturer and distributor channels, with datasheets and certificates of conformity available on request. Whether you're specifying a new distribution board, replacing an obsolete breaker on a shutdown deadline, or sourcing a full parts list for a panel build, our stock and supplier network covers the range below. Electrical Product Families Category Typical Use Browse Miniature Circuit Breakers (MCBs) Final circuit overcurrent protection, DIN rail mounted MCBs Molded Case Circuit Breakers (MCCBs) Higher-current distribution and main protection MCCBs Contactors Motor and load switching in control circuits Contactors Contactor Relays & Thermal Overload Relays Motor protection and auxiliary switching Contactor Relays / Thermal Overloads Isolator Switches & Switch Disconnectors Safe isolation points for maintenance Isolators / Switch Disconnectors RCCBs & RCBOs Earth leakage / residual current protection RCCBs / RCBOs Enclosures & Cabinets Panel housings, IP-rated for indoor/outdoor use Enclosures Busbars & Transformers Power distribution within panels and between phases Busbars / Transformers Where This Gets Used These parts move through panel-building and switchgear assembly, food and beverage plants, water treatment works, commercial and industrial building services, and manufacturing lines where a tripped breaker or failed contactor means downtime. We also handle obsolete and discontinued part numbers for sites still running older distribution boards that a manufacturer no longer lists. Sourcing Electrical Products Worldwide We hold and source genuine electrical protection and switching gear for panel builders, electrical contractors and industrial maintenance teams across the UK, the Gulf and South Asia, with same-week options on common MCB, contactor and isolator part numbers and sourced lead times on higher-current MCCBs, custom enclosures and legacy/obsolete parts. Brands we regularly supply from this range include ABB (drives, switchgear, motors) and Siemens (SIMATIC control gear and protection devices) — see those pages for brand-specific ranges. These are our most active regions, but we quote and ship worldwide — get in touch and we'll confirm lead time and pricing for your location. Need control panel or automation components instead of protection/switching gear? See our Electrical Controls range. Request a Quote Send us your part number, BOM or panel drawing and we'll come back with pricing, lead time and documentation. Request a quote or contact our team directly. Frequently Asked Questions Do you supply genuine, traceable electrical components? Yes — all electrical products we supply are genuine and sourced through manufacturer or authorised distributor channels, with certificates of conformity available on request. Can you match an obsolete or discontinued part number? Often, yes. We regularly source legacy MCBs, contactors and switchgear for older distribution boards where the original manufacturer has stopped listing the part — send us the part number or nameplate details and we'll check. What's the difference between this page and Electrical Controls? This page covers circuit protection, switching and distribution hardware (breakers, contactors, isolators, enclosures). Our Electrical Controls page covers control-panel and automation components. Do you deliver outside the UK? Yes, we ship worldwide, with the UK, Gulf and South Asia among our most active regions. How fast can you quote? Send your part number or BOM through our quote request form and we'll typically respond the same working day.

Instrumentation

4 products

Instrumentation is how a plant actually knows what's happening inside it — pressure, temperature, flow and level are invisible until an instrument turns them into a number or a signal someone (or something) can act on. Z & F Corporation Ltd supplies genuine measurement instrumentation for process, utility and manufacturing plants, sourced through manufacturer and authorised distributor channels with full documentation on request. Pressure Bourdon gauges, diaphragm seals and 4–20mA transmitters for local indication or loop-powered monitoring. Temperature Thermocouples, RTDs and temperature transmitters, with sheath materials and connection heads matched to the process. Flow Vortex, magnetic and differential-pressure flow meters for liquids, gases and steam across a wide range of line sizes. Level Float, ultrasonic and radar level instruments for tanks, vessels and sumps, including point-level switches. Most instrumentation questions come down to two things: what the process actually needs measured (range, accuracy, and how fast it changes), and how that reading needs to reach the rest of the plant — a local dial is enough for a walk-by check, but a control loop or SCADA system needs an electronic output, usually 4–20mA or a digital protocol such as HART or Modbus. Get the output type right and the rest of the specification usually follows from the process conditions. Pro tip — If an instrument is replacing an existing one, check the output signal type (analogue vs digital) before the range or accuracy — a perfectly good transmitter is still the wrong part if the control system can't read its output. These are the instrument families we quote most often, and our sourcing network covers projects worldwide, including the Gulf and South Asia. Send us a tag number, datasheet or existing instrument model and request a quote — we'll confirm fit, lead time and documentation.
