Built to withstand the demands of workshop and site use, this heavy-duty instrument features a clear 6-digit LCD display with 12mm digits for easy reading in various lighting conditions. Housed in a protective high-impact rubber boot, the MM20 combines durability with practical functionality. The rugged case includes an integral stand for hands-free operation, whilst the data-hold function allows you to freeze readings for convenient recording. This multimeter is ideal for electricians, maintenance engineers and automotive technicians who require reliable measurements of voltage, current, resistance and temperature. The unit measures both AC and DC voltage up to 600V, DC current up to 10A, and resistance up to 2MO with accuracy ratings ranging from ±0.5% to ±2% depending on the range selected. The included temperature probe extends measurement capability from -40°C to 1000°C, making this instrument particularly versatile for HVAC work, appliance testing and engine diagnostics. Additional functions include audible continuity testing for quick circuit verification, plus diode and transistor testing modes for component-level diagnostics. Supplied complete with a full set of test leads and probes, the MM20 arrives ready for immediate use. The low battery indicator ensures you're always aware of power status, and the meter conforms to IEC 1010 safety standards. At just 260g and measuring 140 x 70 x 35mm, this compact multimeter is easily portable between jobs. Features and Benefits: • Eight measurement functions cover voltage, current, resistance, temperature, continuity and component testing • High-impact rubber boot protects against workshop knocks and drops • Data-hold function freezes readings for convenient recording • Temperature probe included for measurements from -40°C to 1000°C • Integral stand enables hands-free operation • Clear 6-digit LCD display with 12mm digits for excellent readability • Complete with test leads and probes for immediate use Specifications: Brand: Sealey Nett Weight: 260g AC Voltage (Accuracy): 200V, 600V (±2%) DC Voltage (Accuracy): 200mV (±0.5%), 2V (±0.8%), 20V (±0.8%), 200V (±0.8%), 600V (±0.8%) AC Current (Accuracy): No DC Current (Accuracy): 2mA (±1%), 20mA (±1%), 200mA (±1.2%), 10A (±2%) Resistance (Accuracy): 200O, 2kO, 20kO, 200kO (±0.8%), 2MO (±1.2%) Capacitance (Accuracy): No Temperature (Accuracy): Range; -40°C-1000°C, (±1% up to 400°C), (±2% over 400°C) Frequency (Accuracy): No Duty Cycle: No Continuity Audible: Yes Diode Test: Yes Transistor Test: Yes High-Impact Rubber Case: Yes Digits x Height: 6 x 12mm Low Battery Indicator: Yes Battery (Supplied): 1 x 9V Information: Integral Stand Size (L x W x D): 140 x 70 x 35mm Weight: 260g Conformity: IEC 1010

Sellers offer a range of delivery options, so you can choose the one that’s most convenient for you. Many sellers offer free delivery. You can always find the postage cost and estimated delivery date in a seller’s listing. You'll then be able to see a full list of delivery options during checkout. These can include: Express delivery, Standard delivery, Economy delivery, Click & Collect, Free local collection from seller.
Your options for returning an item vary depending on what you want to return, why you want to return it, and the seller's return policy. If the item is damaged or doesn't match the listing description, you can return it even if the seller's returns policy says they don't accept returns. If you've changed your mind and no longer want an item, you can still request a return, but the seller doesn't have to accept it. If the buyer changes their mind about a purchase and wants to return an item, they may need to pay return postage costs, depending on the seller's return policy. Sellers can provide a return postage address and additional return postage information for the buyer. Sellers pay for return postage if there's a problem with the item. For example, if the item doesn't match the listing description, is damaged or defective or is counterfeit. By law, customers in the European Union also have the right to cancel the purchase of an item within 14 days beginning from the day you receive, or a third party indicated by you (other than the carrier) receives, the last good ordered by you (if delivered separately). This applies to all products except for digital items (e.g. Digital Music) that are provided immediately to you with your acknowledgement, and other items such as video, DVD, audio, video games, Sex and Sensuality products and software products where the item has been unsealed.
Sellers have to offer a refund for certain items only if they are faulty, such as: Personalised items and custom-made items, Perishable items, Newspapers and magazines, Unwrapped CDs DVDs and computer software. If you used your PayPal balance or bank account to fund the original payment, the refunded money will go back to your PayPal account balance. If you used a credit or debit card to fund the original payment, the refunded money will go back to your card. The seller will effect the refund within three working days but it may take up to 30 days for Paypal to process the transfer. For payments funded partially by a card and partially by your balance/bank, the money taken from your card will go back to your card and the remainder will return to your PayPal balance.
