Clamp Meter Manufacturer for HVAC and Refrigeration Service
As a Instruments&Tools-Clamp Meter Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Ningguo Kingcool Import and Export Co., Ltd supplies Clamp Meter instruments as part of our one-stop appliance parts range. We are a China clamp meter supplier serving HVAC contractors, refrigeration workshops and electrical maintenance teams. Our clamp meters are selected for non-contact current measurement, voltage, resistance and continuity testing on air conditioning, refrigeration and general electrical systems.
Our core manufacturing is metalized polypropylene film capacitors, with an annual capacity of 10 million pieces. That electrical component background informs how we specify and source test instruments for capacitor, compressor and motor circuits. We combine industry and trade to support fragmented, personalized orders across more than a dozen export markets.
Our Clamp Meter Range
We currently offer two digital clamp meter models for HVAC and refrigeration diagnostics. Both are compact, hand-held instruments intended for field service and workshop benches.
| Model | Type | Key Features | Typical Application |
|---|---|---|---|
| Digital Clamp Meter MT87 | AC clamp meter | Black and yellow housing; non-contact AC current measurement; voltage, resistance and continuity functions | Compressor and motor current checks; HVAC field service |
| MT87C Digital Multimeter with Back-Light | Clamp meter with back-light | Back-lit display; DC voltage, AC voltage, resistance and continuity test functions | Low-light panels; control board and capacitor circuit diagnostics |
For related test and service instruments, see our PRODUCT overview, which includes multimeters, infrared thermometers and refrigeration tools.
Application Fit in HVAC and Refrigeration
Clamp meters are used wherever current must be measured without opening the circuit. In air conditioning and refrigeration work, that means checking compressor running current, fan motor load, and capacitor charge/discharge behavior. Our instruments are selected to match these tasks.
- Compressor current: Clamp around the supply conductor to compare measured current against nameplate RLA or FLA.
- Fan and blower motors: Verify motor current on indoor and outdoor units, including shaded-pole and axial fan motors.
- Capacitor circuits: Use voltage and resistance functions to confirm discharge and identify open or shorted run capacitors.
- Control panels: Trace relay, contactor and transformer circuits where access is limited.
- Refrigeration racks: Monitor current on condensing units and refrigerant recovery equipment.
These instruments also support general electrical maintenance for washing machine motors, drain pumps and home appliance control boards. Our wider Air-Conditioner Parts and Refrigerator Parts ranges cover the components being tested.
Critical Specifications We Confirm
When preparing a clamp meter proposal, we confirm the measurement range, jaw opening, display resolution and safety rating required for your service environment. The table below lists the specification areas we review with each order.
| Specification Area | What We Confirm | Why It Matters |
|---|---|---|
| AC current range | Maximum measurable current and resolution | Must cover compressor inrush and running current |
| Jaw opening | Clamp diameter and conductor fit | Determines whether the meter fits around thick cables and busbars |
| Voltage and resistance functions | DC/AC voltage range, resistance range, continuity | Supports capacitor and control circuit diagnostics |
| Display | Back-light availability, digit height, count | Readability in plant rooms and outdoor units |
| Power source | Battery type and expected service life | Field replacement convenience |
| Housing and safety | Insulation, CAT rating, drop resistance | Operator protection on live circuits |
Configuration and Ordering Options
We configure clamp meter orders around the service environment and the way your technicians work. Options include display type, jaw size, included test leads, carrying case and packaging format.
- Display: Standard LCD or back-lit LCD for low-light work.
- Jaw size: Compact jaw for control panels or larger jaw for compressor cables.
- Accessories: Test leads, batteries, carrying pouch or hard case.
- Packaging: Individual retail box, bulk carton or private-label carton.
- Documentation: English user manual; other languages available on request.
Because we also supply capacitors, contactors, transformers, relays and motors, we can consolidate clamp meters with the components your team tests. This reduces separate shipping and documentation for mixed appliance parts orders.
Quality Control and Acceptance
Our capacitor production uses high-precision slitting and winding equipment and testing equipment with real-time monitoring. We apply the same attention to incoming inspection for clamp meters: function checks, display verification and accessory completeness before packing.
For project orders, we can agree on acceptance criteria in advance. Typical checks include:
- Current measurement against a known reference load.
- Voltage and resistance function verification.
- Continuity buzzer and back-light operation.
- Jaw alignment and smooth opening/closing.
- Battery compartment and lead connection integrity.
- Carton quantity, labeling and shipping marks.
We document the inspection results and include them with the shipping documents. Where third-party inspection is required, we coordinate the schedule with the nominated agency.
Installation, Maintenance and Spare Parts
Clamp meters are hand-held instruments; installation is limited to battery insertion and lead connection. We supply the correct battery type and a user manual with each unit. For maintenance, we recommend periodic function checks and replacement of test leads if insulation is damaged.
Spare parts we can supply with clamp meter orders include test leads, batteries and carrying cases. For larger service fleets, we can include a small stock of these consumables so your team avoids downtime.
Information We Use to Configure Your Solution
To prepare a clamp meter configuration and quotation, we need the following project inputs. The more detail you provide, the more precisely we can match the instrument to your work.
- Application: HVAC service, refrigeration, appliance repair or general electrical maintenance.
- Measurement targets: Maximum AC current, voltage range, resistance and continuity needs.
- Environment: Indoor/outdoor use, ambient light level, temperature range.
- Quantity: Single units, service kits or bulk order for a distributor.
- Packaging and branding: Neutral carton, retail box or private label.
- Documentation: Language of user manual and any certificate requirements.
- Delivery: Destination port, preferred Incoterm and target shipment window.
We respond to inquiries within 12 hours on working days. Send your project details through the contact form or by phone/WhatsApp at +86-18110862602.
Frequently Asked Questions
What clamp meter models does Kingcool supply?
We supply the Digital Clamp Meter MT87 and the MT87C Digital Multimeter with Back-Light. Both are hand-held instruments for AC current, voltage, resistance and continuity testing. We can also source related multimeters and refrigeration tools as part of a combined order.
Can I order clamp meters together with HVAC and refrigerator parts?
Yes. We operate as a one-stop supplier for air conditioner, refrigerator, washing machine and refrigeration parts. You can combine clamp meters with capacitors, contactors, relays, motors, thermostats and other components in a single shipment.
Do you offer private-label or custom packaging for clamp meters?
We can discuss private-label cartons and custom packaging for volume orders. Provide your artwork, carton dimensions and labeling requirements, and we will confirm feasibility and lead time with the quotation.
What information do you need to quote a clamp meter order?
We need the application, required measurement ranges, quantity, packaging preference, manual language, destination port and target delivery date. With those details we can propose a suitable model and configuration.
How are clamp meters inspected before shipment?
Each unit is checked for current, voltage and resistance function, display operation, jaw action and accessory completeness. We document the inspection and can coordinate third-party inspection if required.
Which markets do you export clamp meters to?
Our products are exported to more than a dozen countries in the Middle East, Africa, South America and Southeast Asia. We support global B2B buyers with export documentation and consolidated appliance parts shipments.
