There are few true wireless multimeters on the market. Fluke is right up there with the best of them, including its 233 model which has a removable head. There are several data logging meters on the market that transmit their data to smartphones and computers via Bluetooth. The diminutive Mooshimeter, meanwhile, uses a smartphone as its display.
Fluke 3000 FC
Neither a data logger nor a full range meter, the 3000 is nevertheless classed as a wireless digital multimeter. It is designed to work with extra modules – including amperage, voltage and temperature (sold separately) – which gives it more functionality, but which drives up the cost.
It is best employed in electrical maintenance, to monitor systems from afar via Bluetooth connectivity. It does this through something called Fluke Connect, which allows it to talk to smartphones and computers. Data capture is limited on this meter, however, and the software is also a bit stifling, though you have live graphing and can video call the data with ShareLive.
The meter itself is True RMS and is as strong as any other Fluke, though it lacks amperage and micro-amps ranges. There is a milliamp range, along with AC and DC voltage (to 1000V), resistance, continuity, capacitance and frequency ranges. The display can show all module data and the present reading simultaneously, plus it is backlit.
Although it doesn’t data log, the 233 is more functional in itself than the 3000FC. This is a full multimeter – albeit minus a micro-amps range – that is ideal for working in hazardous environments as it has a detachable head.
You can leave the meter connected to a system within a control panel or motor, for instance, while you monitor the display in safety. It is True RMS responsive, too, meaning accurate measurements of AC drives. The 233 can measure 10A continuously, 20A in bursts, and also has voltage, capacitance, frequency and temperature ranges.
This is a pretty rugged wireless digital multimeter, too, and is rated to CAT-IV 600V. This makes it okay to work on three phase power systems at installation source as it has the electronic input protection to handle high energy surges.
Mooshimeter Wireless Multimeter
The Mooshimeter is an unusual multi-channel DMM / data logger that couples with a smartphone via Bluetooth, using it for its display. It works with both iOS and Android devices and can measures current, voltage, resistance and temperature. It can also measure frequency and perform diode checks. Two of these values can be measured simultaneously as opposed to a traditional meter, which typically does just the one.
Specs include voltage to 600V DC, 420V AC, 10A continuous, and resistance to 20MΩ. Of its data logging capability, it can data log data at various intervals, including one second, 10s and one minute up to a period of six months. Data can be stored to an SD card. Range to smartphones is up to 50m (line of sight).
Basic DC voltage accuracy is in the 0.5% range. The Category rating is CAT-III 600V and three 4mm test leads, batteries (x2 AA), alligator clips and a case are included.
Others: Any ‘Fluke Connect’ meter is also wireless and there are various devices out there with smartphone connectivity, such as the Tekpower TP9605BT. A True RMS data-logging meter, it is full range and can also do micro-amps, though lacks on surge protection. The Agilent U1253B and Extech 540 have similar abilities.
As far as wireless digital meters go, the Fluke 3000 FC is a useful tool that can data log voltage, amperage and temperature through extra modules. While of use for remote maintenance work, it’s a shame they never made the 287/9 wireless-capable as you’d have a full range meter/data logger.
The Fluke 233 is more of a no mess, wireless meter that is perfect for working in dangerous environments. With its removable head, it allows users to monitor systems with all the ability of a full range, single unit multimeter. The Mooshimeter is a great, little concept meter that twins with a smartphone to display results. Go with the Tekpower TP9605BT if you want to save.
