Multimeters for the Industrial/Commercial Electrician
An ideal general-purpose multi-meter for the rigours of the industrial / commercial electrician the APPA 70 series meters are all well configured for the rigours of the job. Being a tougher environment electrically, this series is very sensibly rated Cat 4, an excellent investment. Given the time the meters are used on the job, APPA has also spent a lot of time making them ergonomic to use with just one hand, plus being very nice indeed to hold. A rubber outer sleeve adds extra robustness but also includes useful features like a tilt stand, facility to hang the meter off a nail or hook at the switchboard, and convenient test lead storage.
Without doubt this meter is the most popular choice for the industrial professional! It is really built for the job, combining APPA’s famous ergonomic operation with a robust shock proof Cat 4 meter that is packed with relevant features. Naturally, accuracy of reading is correctly-specified at an impressive 0.08% basic DC V accuracy. Low impedance voltage detection is also combined with non-contact voltage detection for clear and unambiguous warnings of voltage actually being present in industrial situations. When it comes to industrial voltage and current readings in plant where non-symmetrical waveform distortion so often exists, normal True RMS meters have major errors but the APPA 99II has the “AC+DC True RMS” facility to allow accurate reading regardless! Its backlit 6000 count LCD offers excellent resolution and has a high resolution bar graph analogue display as well to aid assessment of rapidly-changing values. Naturally extra features like temperature, smart data hold, and fast peak hold all are included to make the APPA 99II a first rate choice.
There are those in the industrial and commercial sector that really have need of more features than even the APPA 99II. Fear not...the APPA 505 assembles in one meter all that might possibly be dreamed of! Building on the acclaimed APPA ergonomic Cat 4 shockproof platform, the APPA 505 adds an all-weather housing and automatic backlighting feature to allow easy use in even the harshest environments. Resolution is amazing, combining a 100,000 and 10,000 count digital displays (as well as analogue one), whilst reading precision is as you would expect at an incredible 0.015% basic DCV accuracy. So far as features go the APPA 505 really ‘has them all’, its simple navigation key drive and on-screen menu makes sure all are accessed as simply as possible. Amongst the highlights of the meter, one can list and auto AC+DC True RMS mode, on-board data logging and storage with supplied software, ultrafast peak hold capture, duty factor for pulse chain assessment, dBm & dB measurement, and simultaneous frequency indication with voltages and current readings. The rest of the features of this “must have” meter are what you would expect!
