The Tonghui has arrived. It is ideal for measuring small RF components. It has a resolution of 100 microohms, 1 nanohenry and 0.001 picofarad. There is no need to buy Kelvin clips. It comes with a complete set, including SMD and ordinary multimeter clips. TH2822 series are equipped with the following contents: • TH2822/TH2822A/TH2822C handheld LCR meter • Instruction manual (in Chinese) • Mini USB Interface Cable • Short-circuit plate • *9V Alkaline battery or 8.4 rechargeable battery • *AC adapter (240V, 4mm) • *TH26027A Kelvin clip test leads • *TH26009C SMD test tweezers • Red / Black Banana plugs—Crocodile clip Test Leads It also has a USB interface for data transfer. This requires a special driver available from www.tonghui.com.cn. The only problem is the charger is 240V to 12V with a 4mm connector. This is a problem for North America customers, but the needed chargers appear to be available at Amazon. For example, see https://www.amazon.ca/SHNITPWR-Universal-Switching-Adjustable-Transformer/dp/B08N46GMM8/ The manual is available all over the place, for example at http://file.yzimgs.com/327099/2011101217170714.pdf

It looks identical to my Agilent U1732B, thjough I think the Agilent's spec is poorer. It was replaced by a U1732C which may be closer thjough both are going back a way now. Presumably Agilent badged it and it has continued to improve. I don't know whether there's a corresponding Keysight version.
